+<p>The 9.54.0 release is a maintenance release, and also adds new functionality.
+<br>
 <p> Highlights in this release include:
 <ul>
 <li>
-<p>The 9.53.3 release is primarily maintenance.
+<p>Overprint simulation is now available to all output devices, allowing
+quality previewing/proofing of PostScript and PDF jobs that rely on overprint.
+See the <code>-dOverprint</code> option documentation in:
+<a href="Use.htm#Overprint">Overprint</a>
 </li>
 <li>
-<p>Issues arose with 9.53.0/1/2 that prompted the release of a <code>.3</code> patch:
-<ul>
-<li>A crash (or silent, erroneous exit) on 64 bit Windows and other LLP64 type environments.</li>
-<li>What appears to be a compiler optimiser bug in 64 bit Windows builds with Visual Studio 2019</li>
-<li>A crash related to management of ICC profile objects</li>
-<li>A crash on SPARC hardware due to an alignment mismatch in the bitmap cache</li>
-<li>A parameter type mismatch that would cause Ghostcript to error out during initialisation,
-which affected 64 big, big endian architectures.</li>
-<li>An expected side effect of another change that prevented multithreaded rendering and background
-rendering from working correctly.</li>
-</ul>
-<p>Details of those can be found in the changelog.
+<p>The &quot;docxwrite&quot; device adds the ability to output to Microsoft Word
+&quot;docx&quot; (it currently only handles text).
+See: <a href="VectorDevices.htm#DOCX">docxwrite</a>
 </li>
 <li>
-<p>The most obvious change is the (re-)introduction of the patch level to the version number,
-this helps facilitate a revised policy on handling security related issues.
-<p>To clarify: in the event we decide to release a patch revision, it will <em>replace</em> the release
-with the previous patch number. Release notes, highlights and warnings will remain the same, except for the
-addition of whatever fix(es) prompted the patch.
+<p>The pdfwrite device is now capable of using the Tesseract OCR engine when it is
+built into Ghostscript to improve searchability and copy and paste functionality when
+the input lacks the metadata for that purpose. See: <a href="VectorDevices.htm#UseOCR">UseOCR</a>
 </li>
 <li>
-<p>Our efforts in code hygiene and maintainability continue.
+<p>Ghostscript/GhostPDL now includes a &quot;map text to black&quot;
+function, where text drawn by an input job (except when drawn using a
+Type 3 font) can be forced to draw in solid black. See:
+<a href="Use.htm#BlackText">BlackText</a>
 </li>
 <li>
-<p>We have added the capability to build with the Tesseract OCR engine. In such
-a build, new devices are available (pdfocr8/pdfocr24/pdfocr32) which render the
-output file to an image, OCR that image, and output the image "wrapped" up as a
-PDF file, with the OCR generated text information included as "invisible" text
-(in PDF terms, text rendering mode 3).
-<p>Due to some patches to the Tesseract sources that are required (integrated
-upstream, but awaiting release), time constraints, and the experimental nature
-of the feature, we only support including Tesseract from source, not linking to
-Tesseract shared libraries. Whether we add this capability will be largely
-dependant on community demand for the feature.
-<p>See <a href="https://www.ghostscript.com/ocr.html">Enabling OCR</a> for more details.
+<p>Ghostscript/GhostPDL now supports simple N-up imposition &quot;internally&quot;. See:
+<a href="Use.htm#NupControl">NupControl</a>
 </li>
 <li>
-<p>We have added Python bindings for the <code>gsapi</code> interface, can be found
-in <code>demos/python</code>. These are experimental, and we welcome feedback from
-interested developers.
-</li>
-<li>
-<p>For those integrating Ghostscript/GhostPDL via the <code>gsapi</code> interface, we
-have added new capabilities to that, specifically in terms of setting and interrogating
-device parameters. These, along with the existing interface calls, are documented in:
-<a href="API.htm">Ghostscript Interpreter API</a>
-</li>
-<li>
-<p><b>IMPORTANT:</b> In consultation with a representative of
-(<a href="http://www.openprinting.org">OpenPrinting</a>) it is
-our intention to deprecate and, in the not distant future, remove the
-OpenPrinting Vector/Raster Printer Drivers (that is, the <code>opvp</code>
-and <code>oprp</code> devices).
-<p> If you rely on either of these devices, <b><i>please</i></b> get in touch with
-us, so we can discuss your use case, and revise our plans accordingly.
+<p>Our efforts in code hygiene and maintainability continue.
 </li>
 <li>
-<p>IMPORTANT: We have forked LittleCMS2 into LittleCMS2mt (the "mt" indicating "multi-thread").
-LCMS2 is not thread safe and cannot be made thread safe without breaking the ABI. Our fork
-will be thread safe and include performance enhancements (these changes have all be been
-offered and rejected upstream). We will maintain compatibility between Ghostscript and LCMS2
-for a time, but not in perpetuity. If there is sufficient interest, our fork will be
-available as its own package separately from Ghostscript (and MuPDF).

+<p>
+    Bug 703741: clear xstate_change flag on gsave<br>
+<br>
+    xstate_change is used (partly) to track whether ExtGState parameters have<br>
+    changed since the last &quot;q&quot; op, and thus whether we need to set them back again<br>
+    (for the benefit of the pdf14 compositor) on the &quot;Q&quot; op.<br>
+<br>
+    Previously, the flag was inherited by the &quot;new&quot; gstate created by a gsave,<br>
+    so we could end up trying to reset the ExGState params at the wrong point.<br>
+<br>
+    This is especially problematic with internally triggered gsave/grestore for,<br>
+    for example, rendering glyphs, or accumulating patterns, etc.<br>
+<br>
+    In other words, we currently can end up with a sequence like:<br>
+<br>
+    q<br>
+    &lt;change ExtGState params&gt; &lt;- set the xstate_change flag<br>
+    q &lt;- flag still set<br>
+    q &lt;- flag still set<br>
+    Q &lt;- reset the ExtGState params, flag still set<br>
+    Q &lt;- reset the ExtGState params, flag still set<br>
+    Q &lt;- reset the ExtGState params, restores to gstate without flag set<br>
+<br>
+    Whereas what we want is:<br>
+<br>
+    q<br>
+    &lt;change ExtGState params&gt; &lt;- sets the xstate_change flag<br>
+    q &lt;- flag not set (still set in a gstate lower down the stack)<br>
+    q &lt;- flag not set (still set in a gstate lower down the stack)<br>
+    Q<br>
+    Q &lt;- this returns the gstate with the flag to the top of the gstate stack<br>
+    Q &lt;- reset the ExtGState params, restores to gstate without flag set<br>
+<br>
+    So, reset the flag during the gsave.<br>

+    pdfwrite - fix FastWebView with multiple put_params() calls<br>
+<br>
+    When testing this I must have used a setup which either set the<br>
+    OutputFile before setting FastWebView, or set them simultaneously. If we<br>
+    have the two assignments in different calls, and the first call is not<br>
+    to set OutputFile, then the assignment of FastWebView will not work.<br>
+<br>
+    This is because we didn't check whether OutputFile was set before<br>
+    checking if it was seekable, obviously a NULL file is not seekable! This<br>
+    caused us to reset 'Linearize'. The subsequent call to set OutputFile<br>
+    could not re-enable Linearize, and so linearization would not be<br>
+    enabled.<br>
+<br>
+    The fix here is simply to check that pdev-&gt;flle is not NULL before<br>

+    Automate tesseract build compatibility with clang++<br>

+<br>
+    Also, on Linux (at least) clang++ requires -stdlib=libstdc++ in order to<br>

+    Fix crash in display device (seen with apitest.c).<br>
+<br>
+    When calculating the size for the display, we setup a<br>
+    fake gx_device_memory to call the calculation routine<br>
+    with. Because we hadn't initialised the graphics_type_tag<br>
+    sometimes it would incorrectly assume there was 1 more<br>
+    plane than there should be.<br>
+<br>
+    In calculating the required size, it would therefore add<br>
+    in bitmap_raster(plane[i].depth * width) more bytes for<br>
+    that plane. If plane[i].depth was negative, this would<br>
+    cause the amount of memory we allocate to shrink, and<br>
+    accordingly, we'd allocate too little memory.<br>
+<br>
+    The fix is to ensure that the fake device is always<br>
+    zero'd to start with.<br>

+    Drop DynaLab special bbox stretching of metrics<br>
+<br>
+    For historical reasons relating to glyph caching the zchar42_set_cache<br>
+    code used the minimum and maximum of the glyph bounding box and font<br>
+    bounding box when setting the metrics of a glyph.<br>
+<br>
+    This was done for DynaLab (one of the FreeType 'tricky' font types),<br>
+    because these fonts abuse the TrueType 'hinting' mechanism.<br>
+    Unfortunately this results in the wrong origin 1 being sent to<br>
+    setcachedevice2, and hence CDevProc when the font is vertically<br>
+    oriented.<br>
+<br>
+    We no longer use this function for clipping, and the remaining client<br>
+    pdfwrite doesn't use it for clipping but very much does use it for<br>
+    gathering font metrics, so it is vital that these be correct.<br>
+<br>
+    Since it's only used by pdfwrite, and testing suggests that DynaLab<br>
+    fonts are not a problem for this, the code has been removed here. If<br>
+    it should ever prove to be required then we should check the Font to<br>
+    see if it is a DynaLab font. MuPDF has a function is_dynalab() for this<br>
+    and we should use that if we prove to need it.<br>

+    Bug 703414 : Halftone artifacts<br>
+<br>
+    There are two different representations of the turn-on-sequence<br>
+    in GS.  One of them uses an array of unsigned short integers that<br>
+    indicate what bits get turned on.  The array stores an address<br>
+    offset into the bitmap tile that is created for a particular level.<br>
+    The decision to use this representation is made in gsht.c<br>
+    in the gx_ht_alloc_theshold_order method and is based upon the<br>
+    width and height of the threshold array which indicates the total<br>
+    number of addresses or offsets into the tile to reference which<br>
+    bits get turned on in the tile by the turn-on-sequence.  The tiles<br>
+    themselves however are forced to have their rows raster aligned meaning<br>
+    that if w*h &lt;= 65535 the offsets into the tile dots can be larger<br>
+    than 65535, which will not fit in the short turn-on-sequence array.<br>
+    The code uses a different representation for the TOS if the number<br>
+    of elements is less than 2000.  Then it stores a pointer to a structure<br>
+    for every element.  That is the &quot;default&quot; implementation.  Here<br>
+    a uint (32-bit) implementation is added for cases where the tile is<br>
+    larger than 65536 (e.g. bigger than 256 x 256).  The implementation is<br>
+    the same as the ushort case, but just uses four byte offsets for the TOS.<br>

+    Bug 703324 - restore fill state after fill+stroke path operation<br>
+<br>
+    The file in bug 703324 fills and strokes a rectangle ('B' operator)<br>
+    and sets the fill constant alpha to 1, and the stroke constant alpha<br>
+    to 0, so that the stroke is not drawn. Pointless but that's what it<br>
+    does.<br>
+<br>
+    It then draws some text.<br>
+<br>
+    Now the clist maintains an 'opacity' member, which is set and reset by<br>
+    (amongst other things) looking at the fill and stroke alpha values. When<br>
+    we do a fill+stroke we set the opacity to the fill alpha, and do the<br>
+    fill, then we set it to the stroke alpha and draw the stroke.<br>
+<br>
+    We then do an 'image_fill_masked' operation to draw the text bitmaps.<br>
+    This device method does not take a graphics state as a parameter and so<br>
+    is unable to set the opacity in the device based on the fill alpha. It<br>
+    simply uses whatever opacity is current at the time. Because the<br>
+    fill+stroke left this at the 'stroke' alpha, this is applied to the text<br>
+    which (because the alpha is 0) is then not drawn.<br>
+<br>
+    In addition the graphics state fill constant alpha value was left with<br>
+    the wrong value, but fixing that wasn't sufficient. However we should<br>
+    do both, and this commit resets the fill constant alpha in the graphics<br>
+    state and recalculates the 'opacity'.<br>

+    Fix seg faults in subclassing<br>
+<br>
+    Commit a754bd375a625368567947b1e1b77ce3e5c06a3f fixed a different class<br>
+    of seg faults, but unfortunately removed a crucial line of code.<br>
+<br>
+    When the child device has pushed a compositor, we still need to check<br>
+    to see if the compositor is pointing at the child device. If it is not<br>
+    then the compositor must have pushed more than a single device, so it<br>
+    is not safe to behave as if the target of the compositor is our child<br>
+    device.<br>
+<br>
+    Originally I had hoped to walk down the forwarding devices until we<br>
+    reach our device, but the actual behaviour of the pdf14 device in<br>
+    combination with the clist, when the final device is ps2write renders<br>
+    that all but impossible, as well as unnecessary.<br>
+<br>
+    In this case the compositor action starts by defining a new device,<br>
+    It then pushes a pdf14_accum device (there are 3, one per device space)<br>
+    it then pushes the pdf14clist device in front of that. Finally it turns<br>
+    the device it first created into a forwarding device, and points its<br>
+    target at the original device.<br>
+<br>
+    So we return with 3 new devices pushed, not just one. However, the<br>
+    final forwarding device is in fact forwarding to the subclassing device<br>
+    and the device reference counting magic is applied to the forwarding<br>
+    device, which means we don't need to dance around with the references<br>
+    to the subclassing device and child.<br>
+<br>
+    We could detect this condition by checking the name of the target device<br>
+    of the pdf14clist forwarding device, but that isn't really any better<br>
+    than simply assuming that the compositor takes care of inserting new<br>
+    devices correctly. The pdf14_accum devices are not forwarding devices,<br>
+    they store the pdf14 device in a member called saved_pdev14, so we can't<br>
+    readily follow that either. Finally there is no way to determine if a<br>
+    device is a forwarding device, or a gx_device_pdf14_accum type which<br>
+    limits the amount of checking we cna perform.<br>
+<br>
+    This is an interim commit to work around the problem, because we are<br>
+    about to do a release. A better fix which eliminates all (we hope)<br>
+    of the hidden assumptions and magic knowledge in the code here<br>
+    will be committed shortly, but may be too risky for the release.<br>

+    Update create_compositor device method, so that it always returns<br>

+    Bug 703589: handle overlapping ranges in TTF format 4 cmaps<br>
+<br>
+    The fonts embedded in this file contain a large number of overlapping/repeated<br>
+    ranges in the format 4 cmap table definition - which is *strictly* not permitted<br>
+    according to the spec.<br>
+<br>
+    For example:<br>
+    scode=117 ecode=117<br>
+    scode=117 ecode=117<br>
+    scode=118 ecode=118<br>

+    scode=121 ecode=121<br>
+    scode=121 ecode=121<br>
+<br>
+    Turns out, other consumers use the *first* mapping they encounter where, because<br>
+    we use a Postscript dictionary to store the cmap table, later definitions<br>
+    overwrite earlier ones.<br>
+<br>

+<p>
+    Fix buffer overrun in ASCIIHexEncode<br>
+<br>
+    This exhibited as a memory corruption error (buffer overrun) in pdfi.<br>
+<br>
+    The ASCIIHexEncode filter is required to write linfeed characters to the<br>
+    output at least every 80 (output characters). Ghostscript chooses to do<br>
+    so every 64 characters. So every 64 characters the filter emits a<br>
+    linefeed, crucially without checking whether there is room in the<br>
+    output buffer.<br>
+<br>
+    In order to determine how many linefeed characters we are going to need<br>
+    to write into any given output buffer we divide the number of characters<br>
+    in the output buffer by 65 (64 characters + linefeed), taking into<br>
+    account any character slaready emiitted (stored as 'count' in the stream<br>
+    state). We subtract that from the size of the output buffer, in order<br>
+    to ensure that there is enough spare space for the linefeeds.<br>
+<br>
+    Unfortunately, this is not sufficient. Consider an output buffer 194<br>
+    bytes in size, on the first pass. We divide that by 65, which tells us<br>
+    that 2 complete buffers will fit, so we need to reserve space in the<br>
+    output for 2 bytes. We subtract 2 from the count, giving 192, We then<br>
+    proceed to write the output data. We write 64 bytes of data, then a<br>
+    linefeed, then 64 bytes of data, then a linefeed, then 64 bytes of data.<br>
+    Total 194 bytes.<br>
+<br>
+    At this point we have exhausted the output buffer, but because we have<br>
+    written 64 bytes, we unconditionally write a linefeed. This is written<br>
+    one byte beyond the end of the buffer.<br>
+<br>
+    There are many ways to address this but I've chosen to change the<br>
+    divisor from 65 to 64. This may mean that occasionally we will write one<br>
+    input character (2 output characters) less than the maximum possible<br>
+    to the output, but it will prevent the possibility of a buffer overrun.<br>

+    Bug 703550: handle escaped percent chars in file access controls<br>
+<br>
+    The separating devices make a (fairly blunt) effort to avoid attempting to use<br>
+    proscribed characters in file names for separations (for example, '/', '\',<br>
+    etc). As part of this some characters can be replaced with escaped percent<br>
+    chars - so the single percent character survives a later call to a formatted<br>
+    string function (sprintf).<br>
+<br>
+    This ended up foxing the file access validation code which added the fully<br>
+    escaped file name string to the permit write table, but later attempted to<br>
+    validate a file name post sprintf, where the escaping had been undone.<br>
+<br>
+    So, add code to remove escape '%' characters before adding the string to the<br>
+    file access permit lists.<br>

+    Added docxwrite device; uses extract library to write docx output.<br>
+<br>
+    Summary:<br>
+        This adds a new docxwrite device which generates docx files.<br>
+<br>
+        Unlike the txtwrite device, we don't output xml for later use by<br>
+        extract-exe or store information about spans in arrays. Instead we call<br>
+        extract functions such as extract_add_char() directly.<br>
+<br>
+    Code changes:<br>
+        Have moved txtwrite and docxwrite common code into new devices/vector/doc_common.{c,h}.<br>
+<br>
+        Shared types and functions are currently:<br>
+            txt_glyph_width_t<br>
+            txt_glyph_widths_t<br>
+            txt_glyph_widths()<br>
+            txt_get_unicode()<br>
+            txt_char_widths_to_uts()<br>
+            txt_calculate_text_size()<br>
+<br>
+    Building:<br>
+        By default we do not build with Extract and there will be no docxwrite<br>
+        device in the final executables.<br>
+<br>
+        To build with Extract, specify the location of the extract checkout to<br>
+        build and link with.<br>
+<br>
+        Unix:<br>
+            ./autogen.sh --with-extract-dir=&lt;extract-dir&gt;<br>
+<br>
+        Windows:<br>
+            Set environmental variable EXTRACT_DIR=&lt;extract-dir&gt; when building,<br>
+            e.g.:<br>
+                EXTRACT_DIR=&lt;extract-dir&gt; devenv.com windows/GhostPDL.sln /Build Debug /Project ghostscript<br>
+<br>
+        On both Unix and Windows we exit with an error message if the specified<br>
+        location does not exist.<br>

+<p>
+    Bug 695925: Implement overprint simulation for all devices<br>
+<br>
+    This adds the capability to simulate overprint including that of<br>
+    spot colors for all devices including gray and RGB devices.  This<br>
+    is achieved by having the PDF interpreter look if overprint<br>
+    is present, the seting of -dOverprint (/simulate /enable /disable),<br>
+    if the page has transparency, and if the page has spot colors.  Depending upon<br>
+    the color model of the device, and if transparency is present,<br>
+    a special push of the pdf14 device may occur.  The pdf14 device<br>
+    buffer collects the data in a CMYK or CMYK+spots buffer and the<br>
+    put_image method in the pdf14 device will map the buffer to<br>
+    the target device color space.   The code was tested with<br>
+    devices that support and do not support spot colors, those that<br>
+    support and do not support alpha channels, tag based devices,<br>
+    gray, RGB, and CMYK devices.  A special test file to check<br>
+    multiple cases was added to the regression suite.  By default<br>
+    -dOverprint is set to /enable, which should result in the existing<br>
+    behavior where by RGB and Gray devices do no show overprint or spot<br>
+    colors and CMYK devices will handle CMYK overprinting and separation<br>
+    devices will show spots and overprint of all colorants.  With<br>
+    -dOverprint set to /disable no device will show overprinting.  With<br>
+    -dOverprint set to /simulate all devices will show overprint and<br>
+    spot colors.   Ray Johnston did the work in the interpreter as<br>
+    well as the device parameter default setup.  I did the pdf14 device<br>
+    changes and testing.  Changes in a variety of locations were required<br>
+    due to the fact that new combinations were encountered, for example<br>
+    we had cases where devn colors were being used with a device that<br>
+    supports tags (bitrgbtags device and pdf14 compositor setup for CMYK+spots).<br>
+<br>
+    One file:<br>
+    tests_private/xps/xpsfts-a4/fts_34xx.xps.pdf    ppmraw  72 now produces<br>
+    an error.  This file should have been throwing an error all<br>
+    along but was being quietly swallowed.  Acrobat will not open<br>
+    the created pdf file and throws and error.  I will open a bug<br>
+    for the issue as it is a problem with the XPS interpreter.<br>

+    oss-fuzz 25846: Store &quot;printable&quot; refs for errors<br>
+<br>
+    When we get an op/dict/exec stack overflow error, we take a copy of the stack<br>
+    in question, and store it in an array (or as much of it as we feasibly can).<br>
+    That allows us to clear enough stack space to allow the error handler(s) to run<br>
+    without losing the information needed to report the error.<br>
+<br>
+    With the exec stack, however, that can (and usually does) include references to<br>
+    &quot;internal&quot; objects, which are really just pointers to arbitrary C structures,<br>
+    (t_struct and t_astruct ref types). Those can contain pointers referencing<br>
+    objects of unrelated and uncertain lifespans, so persistent storage of them is<br>
+    potentially problematic.<br>
+<br>
+    So, when we create that array representation, replace every t_struct and<br>
+    t_astruct object with a printable string representation.<br>
+<br>
+    This isn't a big problem for speed because a) exec stack overflow is a rare<br>
+    error b) for exec stack overflow, we already have to traverse the objects<br>
+    checking for another condition, and c) we already do (basically) the same<br>
+    conversion considerably later, for the benefit of the error handler.<br>

+<br>
+    The test file for this has a number of Type 1 fonts whose CharStrings<br>

+    According to Postscript rules (which Type 1 fonts are supposed to follow),<br>

+    PDF interpreter - work around broken ObjStms (again)<br>
+<br>
+    Bug #703448 &quot; Ghostscript can't read files that poppler, mupdf and Firefox and others can read&quot;<br>
+<br>
+    The problem is in an OObjStm, a compressed representation of various<br>
+    PDF objects. In the example file the ObjStm returns a lone 'mark'<br>
+    object for one of the compressed objects, which is not legal.<br>
+<br>
+    This appears to be the font T1_2 on page 87.<br>
+<br>
+    The mark confuses our counting of the returned objects and that leads<br>
+    to the interpreter falling in a heap.<br>
+<br>
+    There's no trivial way to address this, so I've chosen to use the<br>
+    approach used for error handling in other places; push a specific name<br>
+    onto the stack, and then use that instead of a mark to delimit the<br>
+    portion of the stack of interest.<br>
+<br>
+    Obviously nothing is going to rescue the broken font; but since this is<br>
+    a PDF file which has been OCR'ed I don't think this is a problem as we<br>
+    will not to try to use it for rendering as the text is all 'drawn' in<br>
+    text rendering mode 3 (neither fill nor stroke).<br>
+<br>
+    Because we keep using this I've also added a couple of utility procedures<br>
+    CountToKey and ClearToKey, which work similarly to countomark and<br>
+    cleartomark. Because I wanted to be able to detect a missing key on the<br>
+    stack CountToKey returns a boolean, not just a number.<br>
+<br>
+    I've also used that approach around the verify_page_tree call so that<br>
+    we don't end up with a pile of junk on the stack if it should fall<br>
+    over similar errors in future.<br>
+<br>
+    Finally I tested with the customer supplied file which originally<br>
+    inspired the changes in resolveobjectstream to detect the last kind of<br>
+    broken ObjStm and that file continues to work.<br>

+    Secondly the txtwrite custom text enumerator was not declaring the<br>
+    'pte_fallback' text enumerator member, which meant that it could be<br>
+    relocated without updating the txtwrite text enumerator, leading to<br>
+    seg faults further through the processing.<br>
+<br>
+    This resolves the seg faults on the supplied test file for me, but there<br>

+    under Memento. I'll address these in a later commit or commits.<br>

+    Implement Nup subclass device to support nesting images on a page.<br>
+<br>
+    By using a subclassing device to intercept a few of the device procs<br>
+    (get_initial_matrix, output_page, fillpage, put_params, close_device, and<br>
+    dev_spec_op) pages can be placed on to a page that is eventually output.<br>
+<br>
+    This initial implementation scales the pages on the 'nest' as defined<br>
+    by -sNupControl parameter that is a string of the form &quot;HxV&quot; where H<br>
+    and V are integers controlling nesting across (H) and down (V) the page.<br>
+<br>
+    All pages on the nest are the same size/orientation as the first page of<br>
+    the nest, and if a different PageSize is encountered, any pages on the<br>
+    current nest will be output before starting a new nest.<br>
+<br>
+    In gx_device_set_hwsize_from_media dev_spec_op is used to prevent changing<br>
+    the device width and height (HWSize) for PageSize or .MediaSize params.<br>
+<br>
+    This requires that the graphics library should not assume that HWSize is<br>
+    derived from PageSize and HWResolution, but it allows the intial clip_path<br>
+    for the nested pages to be set from the MediaSize, Margins, and HWMargins<br>
+    in gx_default_clip_box.<br>
+<br>
+    There are a few files that have differences with the 'psdcmyk' devices when<br>
+    tested with -sNupControl=1x1:<br>

+    generally achieved by malloc blocks being 16 byte aligned, and<br>
+    structures have their offsets calculated so that their contents lie<br>
+    at appropriate positions.<br>
+<br>
+    Unfortunately, our malloc routines only align to 8 byte aligned.<br>
+<br>
+    We therefore bend the jpgtop.c code to align the jmpbuf manually.<br>
+<br>
+    Similar tricks are required in the pngtop.c code, which also uses<br>
+    setjmp/longjmp, but a slightly different approach has to be taken<br>
+    as the png routine allocates the structure with the callback in<br>
+    itself, so we don't get to align just that. Instead, we modify the<br>
+    allocation routines that we provide to pnglib so that blocks are<br>
+    correctly padded.<br>

+<br>
+    Bug #703271 &quot;Using oitsample to convert some pdf files to tif errors out with &quot;The export process timed out.&quot;&quot;<br>
+<br>
+    This is for the larger (205 pages) of the two files. The file is badly<br>
+    broken, 3 fonts point to objects which are not dictionaries but are<br>
+    simply integers. In addition at least one of the Form XObjects has a<br>
+    Group entry which also points to an object which is an integer, not a<br>
+    dictionary.<br>
+<br>
+    The Group was corrupting the operand stack leading to later errors. This<br>
+    commit checks the type of the Group (and the BBox since we're making<br>
+    changes anyway) and simply aborts the Group if the type is incorrect.<br>
+<br>
+    Obviously this is going to lead to incorrect output, but at least we<br>
+    can carry on to later pages.<br>
+<br>
+    Note that Acrobat throws errors on pages 168, 169 and 171-175 of this<br>
+    file and renders blank pages for them, so the file is clearly very badly<br>
+    broken.<br>

+    pdfwrite - fix memory leak when converting names into references<br>
+<br>
+    When writing certain kinds of metadata from pdfmarks we need to convert<br>
+    a named object into an indirect reference. The code for doing this<br>
+    assumed that the gs_param_string array was arranged so that each<br>
+    gs_param_string's data member pointed to an individually allocated<br>
+    chunk of memory, so it was safe to replace it.<br>
+<br>
+    This had 2 problems; firstly the original data buffer was not freed,<br>
+    leading to memory leaks. Secondly, and more seriously, not all<br>
+    gs_param_string_arrays are organised this way. Sometimes the array<br>
+    has a single data pointer containing all the entries sequentially,<br>
+    each member of the array is a gs_param_string where the data member<br>
+    points into a location in the string. We cannot free and reallocate<br>
+    the data members from that kind of string array.<br>
+<br>
+    SO this commit modifies the code to make a new copy of the data in the<br>
+    param_string_array in the format expected by the remaining code, and<br>
+    frees the copied data afterwards. This fixes the meory leak and avoids<br>
+    the potential crashes caused by the incorrect assumption.<br>
+<br>
+    Note that the assumption in the code is true when the input is from the<br>
+    PostScript interpreter, but is not true for the input from pdfi and<br>
+    obviously potentially any other front-end.<br>

+    Bug 694692: Handle custom left-sidebearing values.<br>
+<br>
+    Ghostscript was ending up ignoring LSB values read from Metrics dictionaries.<br>
+<br>
+    This stemmed from some confusion about Freetype's incremental interface<br>
+    API get_metrics call. We had taken the references to &quot;overriding&quot; the metrics<br>
+    to mean it allowed for custom metrics to be passed into (and back out of)<br>
+    Freetype. That is not the case: it is intended to allow integrations supporting<br>
+    &quot;incomplete&quot; (primarily TrueType) fonts, such as PCL/XL embedded TTFs, that are<br>
+    permitted to omit certain tables - specifically, in this case, the hmtx and vmtx<br>
+    tables.<br>
+<br>
+    So, this drops that approach, and applies custom LSB values in our code.<br>
+<br>
+    Coincidentally, this also makes gs somewhat immune from a pending change in<br>
+    Freetype related to that get_metrics call.<br>

+    Bug 703214 - treat some kinds of free objects as not free<br>
+<br>
+    The file in Bug 703214 has been edited incrementally a number of times.<br>
+    The bug is actually the creation of the initial file, which declares<br>
+    its xref table as having a section 7 entries long starting at object<br>
+    1.<br>
+<br>
+    In fact, as is normal, the xref table starts at object 0 with the free<br>
+    entry at the start of the linked list. Because of the incorrect<br>
+    subsection header though, a PDF consumer should read this as being<br>
+    object 1, not object 0.<br>
+<br>
+    Obviously *all* the objects are then incorrect.<br>
+<br>
+    The incremental updates then redefined very object *except* object 1.<br>
+    The result of this is that these objects are all correctly defined. The<br>
+    file then attempts to render object 1, which is free. Acrobat can deal<br>
+    with this, which must mean it is ignoring the 'free' status of the<br>
+    object and reading the 'next free object' value as if it were the offset<br>
+    of the object.<br>
+<br>
+    Because the next free object is 0, and object 1 is the first object in<br>
+    the PDF file, and the preceding line is a comment, this actually works<br>
+    though I'm pretty certain its only by sheer luck, it really should not<br>
+    work at all.<br>
+<br>
+    Unfortunately, because of the way the the PDF interpreter reads PDF<br>
+    files and stores xref entires, we cannot easily detect an attempt to<br>
+    use a 'free' object and try to treat it as non-free. We have to do this<br>
+    upfront when we read the xref table. Because this is such a fluke and I<br>
+    believe not likely to be repeatable, I've tried to keep the condition<br>
+    for ignoring the free flag as tight as possible; The generation number<br>
+    must be exactly 65535 (the canonical value for the head of the free<br>
+    list), and the object number must be not zero. In this case only we<br>
+    will store the 'next free object number' as an offset.<br>
+<br>
+    If the object is truly free then either it is unused (in which case we<br>
+    will not use the xref entry) or it should have been superseded by a<br>
+    later incremental update, in which case we still won't use this entry.<br>
+    The only way we could try to use this entry is if the PDF file attempts<br>
+    to use a free entry.<br>
+<br>
+    This might change some handling of other broken files.<br>

+    Searching for a marker in a stream, honor alignment<br>
+<br>
+    When searching for markers in a stream buffer, we were &quot;seeking&quot; to the point<br>
+    in the buffer, and casting to either a byte, ushort or a uint to make the<br>
+    value comparison. But we cannot do that on SPARC because of the strict<br>
+    alignment on that hardware.<br>
+<br>
+    So, we have to &quot;unpack&quot; the individual bytes from the stream to do the value<br>
+    comparison.<br>
+<br>
+    Note: there are slightly confusing comments in the code that mention being<br>
+    &quot;on a 16 bit boundary&quot; and &quot;on a 32 bit boundary&quot; - that's referring to the<br>
+    offset into the buffer, *not* the actual memory address alignment.<br>

+<p>
+    Squashed commit of pdfwrite_ocr branch.<br>
+<br>
+    This introduces OCR operation to the pdfwrite device.<br>
+<br>
+    The full development history can be seen on the pdfwrite_ocr branch.<br>
+<br>
+    The list of individual commits is as follows:<br>
+<br>
+    --------------------------------------------<br>
+    Interim commit for pdfwrite+OCR<br>
+<br>
+    This is the initial framework for pdfwrite to send a bitmap of a glyph<br>
+    to an OCR engine in order to generate a Unicode code point for it.<br>
+<br>
+    This code must not be used as-is, in particular it prevents the function<br>
+    gs_font_map_glyph_to_unicode from functioning properly in the absence<br>
+    of OCR software, and the conenction between pdfwrite and the OCR engine<br>
+    is not present.<br>
+<br>
+    We need to add either compile-time or run-time detection of an OCR<br>
+    engine and only use on if present, as well as some control to decide<br>
+    when to use OCR. We might always use OCR, or only when there is no<br>
+    Glyph2Unicode dictionary available, or simply when all other fallbacks<br>
+    fail.<br>
+<br>
+    --------------------------------------------<br>
+    Hook Tesseract up to pdfwrite.<br>
+<br>
+    --------------------------------------------<br>
+    More work on pdfwrite + OCR<br>
+<br>
+    Reset the stage of the state machine after processing a returned value<br>
+<br>
+    Set the unicode value used by the ToUnicode processing from the value<br>
+    returned by OCR.<br>
+<br>
+    Much more complex than previously thought; process_text_return_width()<br>
+    processes all the contents of the text in the enumerator on the first<br>
+    pass, because its trying to decide if we can use a fast case (all<br>
+    widths are default) or not.<br>
+<br>
+    This means that if we want to jump out an OCR a glyph, we need to track<br>
+    which index in the string process_text_return_width was dealing with,<br>
+    rather than the text enumerator index. Fortunately we are already<br>
+    using a copy of the enumerator to run the glyph, so we simply need<br>
+    to capture the index and set the copied enumerator index from it.<br>
+<br>
+    --------------------------------------------<br>
+    Tweak Tesseract build to include legacy engine.<br>
+<br>
+    Actually making use of the legacy engine requires a different set<br>
+    of eng.traineddata be used, and for the engine to be selected away<br>
+    from LSTM.<br>
+<br>
+    Suitable traineddata can be found here, for instance (open the link,<br>
+    and click the download button):<br>
+<br>
+      https://github.com/tesseract-ocr/tessdata/blob/master/eng.traineddata<br>
+<br>
+    --------------------------------------------<br>
+    Add OCRLanguage and OCREngine parameters to pdfwrite.<br>
+<br>
+    --------------------------------------------<br>
+    Add gs_param_list_dump() debug function.<br>
+<br>
+    --------------------------------------------<br>
+    Improve use of pdfwrite with OCR<br>
+<br>
+    Rework the pdfwrite OCR code extensively in order to create a large<br>
+    'strip' bitmap from a number of glyphs in a single call to the text<br>
+    routine. The hope is that this will provide better context for<br>
+    Tesseract and improved recognition.<br>
+<br>
+    Due to the way that text enumerators work, and the requirement to exit<br>
+    to the PostScript interpreter in order to render glyph bitmaps, I've had<br>
+    to abandon efforts to run as a fully 'on demand' system. We can't wait<br>
+    until we find a glyph with no Unicode value and then try to render all<br>
+    the glyphs up to that point (and all the following ones as well). It is<br>
+    probably possible to do this but it would mean rewriting the text<br>
+    processing code which is quite hideous enough as it is.<br>
+<br>
+    So now we render each glyph in the text string, and store them in a<br>
+    linked list. When we're done with the text we free the memory. If we<br>
+    find a glyph with no Unicode value then on the first pass we take the<br>
+    list of glyphs, create a big bitmap from them and send it to Tesseract.<br>
+    That should then return all the character codes, which we keep. On<br>
+    subsequent missing Unicode values we consult the stored list.<br>
+<br>
+    We need to deal specially with space glyphs (which make no marks) as<br>
+    Tesseract (clearly!) can't spot those.<br>
+<br>
+    Modify makefile (devs.mak) so that we have a preprocessor flag we can<br>
+    use for conditional compilation. Currently OCR_VERSION is 0 for no OCR,<br>
+    1 for Tesseract, there may be higher numbers in future.<br>
+<br>
+    Add a new function to the OCR interface to process and return multiple<br>
+    glyphs at once from a bitmap. Don't delete the code for a single bitmap<br>
+    because we may want to use that in future enhancements.<br>
+<br>
+    If we don't get the expected number of characters back from the OCR<br>
+    engine then we currently abort the processing. Future enhancements;<br>
+    fall back to using a single bitmap instead of a strip of text, if we get<br>
+    *more* characters than expected, check for ligatures (fi, ffi etc).<br>
+<br>
+    Even if we've already seen a glyph, if we have not yet assigned it a<br>
+    Unicode value then attempt to OCR it. So if we fail a character in one<br>
+    place we may be able to recognise it in another. This requires new code<br>
+    in gsfcmap.c to determine if we have a Unicode code point assigned.<br>
+<br>
+    Make all the relevant code, especially the params code, only compile<br>
+    if OCR is enabled (Tesseract and Leptonica present and built).<br>
+<br>
+    Remove some debugging print code.<br>
+<br>
+    Add documentation<br>
+<br>
+    --------------------------------------------<br>
+    Remove vestiges of earlier OCR attempt<br>
+<br>
+    Trying to identify each glyph bitmap individually didn't work as well<br>
+    and is replaced by the new 'all the characters in the text operation'<br>
+    approach. There were a few vestiges of the old approach lying around<br>
+    and one of them was causing problems when OCR was not enabled. Remove<br>
+    all of that cruft here.<br>

+<br>
+    Bug #703105 &quot;PDF file gives &quot;Unable to determine object number...&quot; and output is missing some images.&quot;<br>
+<br>
+    As per the bug thread; the PDF file has annotations which are deeply<br>

+    Form dictionary does not contain a /Resources dictionary so we are unable<br>

+    was a bug in it, it pops an object that was never pushed, resulting in<br>

+    ps2write - fix use of /.HWMargins with ps2write output<br>
+<br>
+    Bug #703017 &quot;When print a file created with pdf2ps command with a PDF driver, the image shifts to the upper right as the number of pages increases.&quot;<br>
+<br>
+    The bug report here is, unfortunately, insufficient to duplicate and<br>
+    resolve the problem. The missing information was supplied quite<br>
+    independently by the user 'vyvup' on the #ghostscript IRC channel. See<br>
+    the #ghostscript logs at around 08:45 on November 9th 2020.<br>
+<br>
+    https://ghostscript.com/irclogs/20201109.html<br>
+<br>
+    The important missing information is that the device must have the<br>
+    Ghostscript-specific page device key /.HWMargins set. When this is set<br>
+    and has non-zero values the offsets are applied cumulatively on every<br>
+    page by the code in pdfread.ps. This is because we set up the page<br>
+    'view' before we save the current setup in the ps2write dictionary<br>
+    under the 'pagesave' key. When we restore back to that at the end of the<br>
+    page it therefore does not remove the translation applied to account<br>
+    for the /.HWMargins.<br>
+<br>
+    Here we just shift the save so that it occurs before we apply the page<br>
+    size setup.<br>

+    pdfwrite - fix Type 4 Chroma-keyed images with Colour Conversion<br>
+<br>
+    Bug #702698 &quot;convert Grayscale error in output&quot;<br>
+<br>
+    Images with a /Mask where the Mask is a range of values, and hence a<br>
+    chroma-keyed image, as opposed to the Mask being an external Image<br>
+    Mask, and therefore a stencil cannot be preserved as such when we are<br>
+    colour converting.<br>
+<br>
+    There is no reliable way to be certain that the colour of the image<br>
+    samples after conversion and the converted Mask values will relate in<br>
+    the same way. Its entirely possible for multiple RGB values to map to<br>
+    the same gray value for instance, and if that happens to be a masked<br>
+    value then pixels will be masked which were not originally.<br>
+<br>
+    This commit checks the ColorConversionStrategy and if it is not<br>
+    LeaveColorUnchanged then we further examine the Mask. If the Mask is a<br>
+    range of values then we consider the colour space of the image.<br>
+<br>
+    If ColorConversionStrategy is not LeaveColorunchanged and the image has<br>
+    a range of values and it is not in the target colour space, then we<br>
+    cannot preserve it. In this case we fall back to either preserving the<br>
+    image, and creating a clip path from the chroma key and the image<br>
+    samples, or (if Version &lt; 1.3) we fall right back to writing each image<br>
+    sample as a filled rectangle.<br>
+<br>
+    This does, of course, result in larger output.<br>

+    Revise font dir global_glyph_code callback API<br>
+<br>
+    The global_glyph_code callback API relies on the name table being avaiable in<br>
+    the gs_lib_ctx and accessible via the gs_memory_t object.<br>
+<br>
+    This is not something that is true, nor can we make it true, for pdfi. Because<br>
+    pdfi is required to integrate with the Postscript interpreter, we cannot have<br>
+    the gs_lib_ctx &quot;top_of_system&quot; pointer point to the pdfi context.<br>
+<br>
+    So, change the global_glyph_code API so it takes a gs_font pointer, instead of<br>
+    a gs_memory_t pointer. The Postscript implementation will work exactly the same,<br>
+    just accessing the gs_memory_t through the gs_font pointer.<br>
+<br>
+    But it allows pdfi to grab it's own context through the gs_font &quot;client_data&quot;<br>
+    pointer.<br>

+    PDF interpreter (with pdfwrite) - another  non-square scaling stroke fix<br>
+<br>
+    Bug #702946 &quot;Ghostscript creates PDF originals with black stripes&quot;<br>
+<br>
+    This is another case of the problem in bug #702900, The commit to fix<br>
+    that problem (d5494de2cab28b91ba360d15b8afffef50a3f421) fixed four<br>
+    places in the code, but missed a fifth place because it is distant from<br>
+    the other four. The offending procedure is setstrokeforTrpreservation.<br>
+<br>
+    This commit adds the required code to that location to go along with the<br>
+    other four, at the same time:<br>
+<br>
+    1) Move the actual code to calculate the width into a procedure<br>
+    2) Have all 5 places use that procedure<br>
+    3) Improve the non-square calculation (hypotenuse/2 instead of hypotenuse)<br>
+    4) Add some 'tolerance' to the equality test.<br>
+<br>
+    The tolerance is because both the test file here and in 702900 have a<br>
+    CTM which is minutely non-square. In this case the c and y scaling<br>
+    differ by less than 0.0001. The intention of this code is actually to<br>
+    deal with non-square resolutions, rather than non-square CTM, and it<br>
+    does so by calculating the hypotenuse of a triangle where the x an y<br>
+    values are the linewidth in each direction. In fact the hypotenuse/2<br>
+    seems a closer approximation. But in any event its incorrect, better to<br>
+    simply use the linewidth if the difference between the two is not very<br>
+    large. (eventually, with pdfi, we will probably do away with this<br>
+    horrible kludge entirely)<br>
+<br>
+    This causes minor but useful progressions in the test suite files<br>
+    Bug695841.pdf, clipping_image_problem.pdf and<br>
+    sumatra/712_-_image_not_displaying.pdf. most notably the latter.<br>
+<br>
+    It also produces slightly less bold output for the test file here,<br>
+    which Acrobat shows as matching precisely with the original.<br>

+    pdfwrite - reorder code to change evaluation order of image parameters<br>
+<br>
+    Bug #702961 &quot;GS produces significantly larger PDFs with same settings as Adobe Distiller&quot;<br>
+<br>
+    This is a problem with the interaction of various image parameters. The<br>
+    relevant options are PassThroughJPEGImages, ColorConversionStrategy and<br>
+    AutoFilterColorImages.<br>
+<br>
+    Because PassThroughJPEGImages is true, we don't set up a compression<br>
+    filter (we don't want to apply compression to a DCT compressed data<br>
+    stream). But ColorConversionStrategy is /sRGB, so we then turn off the<br>
+    PassThroughJPEGImages (we cannot change the colour model and still<br>
+    pass through the original data, obviously). Ordinarily the compression<br>
+    chooser would then select a compression based on the result, but<br>
+    AutoFilterColorImages is false, so the compression chooser is disabled.<br>
+<br>
+    The result is that we write uncompressed image data to the file.<br>
+<br>
+    By reordering the code so that we check the ColorConversionStrategy<br>
+    earlier we can turn off PassThroughJPEGImages before selecting the<br>
+    initial compression which means that this p[articular sequence of<br>
+    options will then work as expected.<br>

+    Bug 702192 Map text to black<br>
+<br>
+    Map all text to black.  This is achieved by altering the<br>
+    color space to DeviceGray with a fill of black during<br>
+    gs_text_begin. When gs_text_release occurs, the color space<br>
+    is restored.  This will only occur with the option -dBlackText<br>
+    and if the text is actually to be drawn.<br>
+<br>
+    When going to a raster device, the stroke and stroke fill of<br>
+    the text is handled with a stroke or stroke fill command.<br>
+    My original plan of storing the old color spaces and client<br>
+    color in the text enumerator will not work in this<br>
+    situation as it the enumerator will have already been<br>
+    destroyed when the stroke or stroke/fill command occurs.<br>
+    For this reason I store the old color space information<br>
+    for the current and alternate color spaces<br>
+    in the graphic state.  The structure holding the information<br>
+    is garbage collected as it is holding objects that may be<br>
+    garbage collected.  We also need to know if the target<br>
+    was a high level device like pdfwrite, as that device<br>
+    will handle the fill AND stroke, and we will need to restore<br>
+    the color space when we tear down the text enumerator.<br>
+<br>
+    gs_text_release needed to have the pgs added as a parameter<br>
+    to allow the possible release of the blacktext structure<br>
+    when the text is released from the other languages. This<br>
+    did not seem to be too big of an issue as gs_text_begin<br>
+    passes the pgs also.  If the pgs is not available, NULL can<br>
+    be passed, and that is done in several locations.<br>
+<br>
+    A new special op was added to let us avoid doing the black<br>
+    text setting if we are constructing a soft mask.  If we did not<br>
+    do this the mask could result in the loss of the text.<br>
+<br>
+    Finally, Type 3 fonts will NOT be affected by this process.<br>
+    Type 3 fonts are often used for actual graphic logos etc.<br>
+    Ken Sharp suggested we not have them affected by this setting.<br>
+    There were also issues with trying to do type 3 fonts in<br>
+    in that the PDF interpreter does some color space settings<br>
+    of its state when dealing with type 3 fonts and this put the<br>
+    interpreter's state out of sync with the graphic library state.<br>
+<br>
+    This was tested with a forced setting of black text enabled.<br>
+    No seg faults or errors occurred.  There were obviously a lot<br>
+    of differences reported (over 33,000). All the images that were available<br>
+    to me with bmpcmp were gone through.  Problems were found<br>
+    and addressed (the soft mask issue for example was found,<br>

+<br>
+    This is not related to the hang, but to the remaining problem with this<br>
+    file and pdfwrite.<br>
+<br>
+    When using pdfwrite with PassThroughJPEGImages the output is incorrect.<br>
+    The reason is that the PostScript program processes the JPEG compressed<br>
+    data, turning a 4-component CMYK image into a single component gray<br>
+    image.<br>
+<br>
+    Obviously if we pass through the original CMYK data, but declare the<br>
+    image a DeviceGray the result is incorrect.<br>
+<br>
+    The only way to deal with this is to turn off the feature. There's no<br>
+    simple way to do this in pdfwrite (where we normally decide to turn it<br>
+    off, for downsampling etc) without disabling it for a number of other<br>
+    useful cases. So instead add a new IdiomSet which replaces part of the<br>
+    PPI ColorUtils ProcSet with a redefined procedure which turns off the<br>
+    PassThroughJEPGImages feature if the ProcSet forces Gray output.<br>

+    pdfwrite - Terminate pass-through images when we have read enough data<br>
+<br>
+    Bug #702964 &quot;EPS file hangs with pdfwrite&quot;<br>
+<br>
+    This is only a partial fix for the bug report, the remaining problem<br>
+    is addressed in a following commit.<br>
+<br>
+    The problem here is that the EPS file includes a ProcSet which processes<br>
+    the JPEG compressed data. It does so using a procedural DataSource for<br>
+    the image operator. Unfortunately the procedure fails to spot that<br>
+    readstring returns 0 bytes and identify this as en EOD. Instead it<br>
+    continues to try and read data, which continuously fails.<br>
+<br>
+    While the cause of the hang is in the PostScript program, it does not<br>
+    normally exhibit because the image operator ceases to read data from the<br>
+    DataSource when it has read enough samples to satisfy the declared<br>
+    Width/Height/BPC. An oversight in the pass-through code meant that the<br>
+    image operator wasn't properly terminating even when enough data had<br>
+    been supplied.<br>
+<br>
+    This commit correctly returns either 0 (require more data) or not-zero<br>
+    (enough data read) so that the operator terminates.<br>

+    &quot;Address&quot; subscript -1 is outside array bounds warning<br>
+<br>
+    There is no immediate prospect of resolving the underlying issue: that the<br>
+    stream code requires the data pointer in the &quot;cursor&quot; to be initialised to the<br>
+    address one byte *before* the beginning of the actual buffer.<br>
+<br>
+    We also do not want to disable the array bounds warning completely, as that<br>
+    risks missing real mistakes.<br>
+<br>
+    So, define a static inline function which does the offending pointer assignment,<br>
+    and disable the warning locally, for only that function. Then have everywhere<br>
+    that uses such a buffer setup call that function, rather than do the assignment<br>
+    itself.<br>
+<br>
+    At the moment, it is only disabled for gcc (and compatible) compilers, we can<br>
+    add others if/as required.<br>

+    pdfimage devices - fix %Invocation and add /Info dictionary<br>
+<br>
+    I'd thought that we had missed off the %Invocation from the PDF output<br>
+    of the PDF image devices, but in fact it was only that the pdfocr<br>
+    devices had it emitted in a surprising place in the file.<br>
+<br>
+    That's fixed here just by moving when we write it so that its location<br>
+    is consistent between the devices.<br>
+<br>
+    Moved some definitions common to both pdfimage and pdfocr from the<br>
+    device's .c files to the pdfimage.h file.<br>
+<br>
+    Added emission of a very basic /Info dictionary. To facilitate future<br>
+    enhancements the number of 'static' (ie predefined) objects has been<br>
+    turned into a #define and we use that wherever possible instead of the<br>
+    previous hard-coded magic number. Because of the font objects required<br>
+    for pdfocr, and the fact that they refer to each other, these still<br>
+    don't use the #define and will have to be manually adjusted if we ever<br>
+    change this again.<br>
+<br>
+    Acrobat ignores the /Info dictionary, apparently it only reads the XML<br>
+    /Metadata values (at least in modern versions), so adding the Info<br>
+    dictionary doesn't help. Creating the XMP metadata is unfortunately<br>
+    quite complicated, we'd need to steal quite a bit of code from pdfwrite<br>
+    and at the moment I think its more trouble than its worth. I may change<br>
+    my mind in future.<br>

+    Bug 702938: Allocating cached glyphs, account for alignment<br>
+<br>
+    For efficiency, the glyph cache allocates &quot;large&quot; blocks of memory into which<br>
+    it parcels out offsets for individual glyph cache bitmaps, as required.<br>
+<br>
+    Since cached glyphs are usually fairly small, and potentially can be short<br>
+    lived, this saves the overheads of &quot;full&quot; memory for every cached glyph.<br>
+<br>
+    Unfortunately, in calculating the offsets for the cached glyph, it was failing<br>
+    to account for the required alignment of the system. In any environment that<br>
+    strictly enforces aligned memory accesses, this will potentially cause a bus<br>
+    error.<br>
+<br>
+    In this case, it was switching the gs_glyph type to a 64 bit type that triggered<br>
+    the issue. But any changed to the contents of the cached_char struct could have<br>
+    resulted in it happening.<br>

+        Updated how zooming is handled<br>
+<br>
+        Zooming is now done through the SmartLoader and is no longer<br>

+    pdfwrite - remove erroneous free from cos_dict_put_copy<br>
+<br>
+    Nancy discovered this one while working on annotations for pdfi. The<br>
+    code here would attempt to free the memory pointing to the key name<br>
+    which is passed as an argument to the function, if the *dictionary*<br>
+    properties were set to free dictionary keys.<br>
+<br>
+    Obviously the function argument is not the same thing as the key stored<br>
+    in the dictionary, so even at first inspection this looks incorrect.<br>
+<br>
+    The key is supplied (much higher up) from a param list, because the pdfi<br>
+    code uses C param lists, where the data is stored in a single large<br>
+    allocation, it is not possible to free an individual key and causes a<br>
+    crash.<br>
+<br>
+    Ghostscript gets away with this for two reasons; firstly it uses a<br>
+    stack param list (which is basically a ref param list) where each key<br>
+    is stored in its own allocation. Secondly the key is not actually<br>
+    allocated, its an entry in the interpreter name table. So when the<br>
+    code in cos_dict_put_copy 'frees' the memory, nothing actually happens,<br>
+    the memory manager just notes that the memory is unused now. This<br>
+    avoids double freeing the memory which would otherwise happen.<br>
+<br>
+    So essentially this code is wrong, and we've been getting away with by<br>
+    sheer luck for decades.<br>
+<br>
+    I tested the modification extensively, including memory leak checks with<br>
+    many files run through pdfwrite and can find no problems with simply<br>
+    removing the line of code.<br>

+<br>
+    Bug #702791 &quot;%d vs. %03d and pdfmark destination page ... points beyond the last ...&quot;<br>
+<br>
+    The PostScript code in the PDF interpreter which looks for<br>
+    file-per-page output, in order to drop Outlines and Dests was<br>
+    only checking for %d not variants liek %03d. This could lead<br>

+<br>
+    The code provided by Peter checks for an odd number of '%'<br>
+    characters instead. This isn't the same test as pdfwrite uses<br>
+    but that is in C and not immediately available in PostScript.<br>
+<br>
+    Since we plan eventually to drop the PostScript implementation<br>
+    of the PDF interpreter and move to a C version, this is fine<br>
+    for the interim.<br>

+    PDF interpreter with pdfwrite fix non-square scaling stroked text<br>
+<br>
+    Bug #702900 &quot;pdfwrite device causes bold text output&quot;<br>
+<br>
+    The PDF interpreter has special code for dealing with line widths and<br>
+    stroked text, this is because we do not preserve the CTM in the input<br>
+    through to the output in pdfwrite.<br>
+<br>
+    What we need to do is figure out what line width with an identity CTM<br>
+    would draw a line the same width as the current line width and CTM.<br>
+    Normally pdfwrite takes care of this itself, but until relatively<br>
+    recently it did not have access to the textmatrix, only the CTM. But for<br>
+    text, by the time we get to the point of emitting the text,, the CTM<br>
+    already includes the Text matrix (Tm).<br>
+<br>
+    So the PDF interpreter (which does have the CTM before the TM is<br>
+    applied) calculates a line width and sets that before sending the text.<br>
+<br>
+    However, when the scaling was non-square we were not doing that, leading<br>
+    pdfwrite to emit the unscaled linewidth. Intriguingly we have no files<br>
+    in the test suite for which this is a problem, all the files where the<br>
+    CTM is non-square it is also close to the identity so not visibly<br>
+    incorrect.<br>
+<br>
+    The file here, however, has a non-identity CTM which is slightly<br>
+    non-square when the text is rendered, and very far from the identity.<br>
+<br>
+    Since we can't tell which scaling to use for the linewidth we 'fudge'<br>
+    it by using the transformed x and y values of the linewidth, as two<br>
+    sides of a triangle, then calculating the hypotenuse. Obviously this<br>
+    won't work for seriously skewed matrices but it seems unlikely we<br>
+    could calculate a reasonable linewidth for that anyway.<br>

+    The problem is to do with image downsampling, and 16 bit images. When<br>

+    reduce the input from 16 bits to 8, so its not necessary for the<br>
+    downsampling code to do this.<br>
+<br>
+    So fix it simply by altering the colour depth form 16 to 8 in the<br>
+    params we pass to the setup code.<br>

+    pdfwrite - fix error handling with broken type 3 fonts<br>
+<br>
+    The test file tests_private\pdf\customer394\problems\normal_537.pdf has<br>
+    a Type 3 font with a CharStrings entry where the value is not a<br>
+    dictionary, it is the null object.<br>
+<br>
+    When trying to capture the outlines of the glyphs in order to rebuild a<br>
+    type 3 font in the output PDF file, pdfwrite detects the error. However<br>
+    due to an oversight when writing the code, the graphics state is not<br>
+    correctly preserved.<br>
+<br>
+    This is because if an error occurs in gs_text_process it unwinds the<br>
+    graphics state stack back to the level stored in the text enumerator<br>
+    at the start of the text processing. But complete_charproc() then<br>
+    proceeds to do another gs_grestore (and the code incorrectly did yet<br>
+    another gs_grestore as well!). This results in the graphics save level<br>
+    being different on exit form text processing to the state on entry.<br>
+<br>
+    Remarkably this doesn't seem to cause a problem, except for the new pdfi<br>
+    interpreter, where the gs_grestore restores back to a point before the<br>
+    type 3 font was present in the graphics state. This leads to the type<br>
+    3 font having a reference count of 1 at the end of processing and the<br>
+    font and all its contents leaking.<br>
+<br>
+    Fix it by updating the 'level' stored in the enumerator actually being<br>
+    used by gs_text_process (which, because this is for capturing glyphs,<br>
+    is not the same enumerator as used by pdf_text_process). Also remove<br>
+    the spurious extra gs_grestore in the error clause.<br>

+<br>
+    A sample file of 1,000 pages from the customer allowed us to reproduce<br>
+    the issue. The file creates MANY fonts (3,398 over the 1,000 pages),<br>
+    and the font_cache list (not really a cache) would have the newest<br>
+    created fonts at the head of the list, but later pages would use<br>
+    fonts created earlier that were at the end of the list.<br>
+<br>
+    Fix this by moving the found font to the head of the list (MRU).<br>
+    On this file, the time on a fast machine went from 152 to 65 seconds<br>
+    and the times for pages does not show the growth seen originally.<br>

+    pdfwrite - fix memory leak in copied font<br>
+<br>
+    This really should have been fixed by an earlier commit, but it had a<br>
+    dumb error. We were freeing cfdata-&gt;names after we'd checked the<br>
+    first entry in the table, instead of checking *every* entry in the<br>
+    table first. In fact the memory was already freed blow so we didn't<br>

+<br>
+    In addition the code to free extra_names was inside the loop and didn't<br>
+    need to be as its a linked list not an array. So move it outside where<br>
+    it will only execute once. Should be a tiny bit faster.<br>

+<p>
+    pdfwrite - fix several memory leaks with colour spaces<br>
+<br>
+    The colour space creation code uses pdf_string_to_cos_name() quite<br>
+    frequently, and it often then passes the resulting cos_value_t to<br>
+    functions such as cos_array_put and cos_dict_put.<br>
+<br>
+    The basic 'put' functions actually copy scalar objects when they are<br>
+    put in an array or dictionary (but they don't copy other composite<br>
+    objects!) so we need to free the object created by<br>
+    pdf_string_to_cos_name() after we've 'put' it.<br>
+<br>
+    The only function to do that is cos_value_free() but that (unreasonably)<br>
+    requires a cos_object_t parameter, even though the cos_value may not<br>
+    be in a cos_object. Since the only use for the cos_object is to<br>
+    retrieve a memory_t pointer in order to free the data used, we can<br>
+    simply replace the cos_object_t * with a gs_memory_t * and use that<br>
+    directly.<br>
+<br>
+    This meant a few places needed to change where cos_value_free() was<br>
+    already being used.<br>
+<br>
+    After that I rationalised the code in gdevpdfc.c to some extent. Instead<br>
+    of the existing mixture of *_put() and *_put_no_copy() calls I've chosen<br>
+    to use *_put() calls throughout and then explicitly free the data which<br>
+    has supposedly been copied.<br>
+<br>
+    We could have used _nop_copy() throughout but that would have meant<br>
+    checking the return value and freeing the original data if the copy<br>
+    failed. It seems simpler just to unconditionally free the original<br>
+    data.<br>
+<br>
+    In one place we also need to check that the original data was not NULL<br>
+    and that it was a scalar type. This is because (as noted above) if it<br>
+    isn't a scalar type the *_put() functions *don't* copy the value, so we<br>
+    don't want to free the original data in this case as it has been<br>
+    transferred to the cos_object.<br>
+<br>
+    Nancy did most of the original work on discovering the actual memory leak<br>
+    here, and suggesting the basic fix, so many thanks!<br>

+    Bug 702761: Improve handline of PS file with many large ReusableStreams<br>
+<br>
+    This file, with its original, non-optimal, method collected 1,000 ReusableStream<br>
+    files, each of which was 7.5Mb, stored as 1,000 arrays of 180 40,000 byte strings.<br>
+    As the file progressed, the load on the GC (garbage collector) to mark-and-sweep<br>
+    all of those strings got slower and slower.<br>
+<br>
+    This change collects the strings in the array of strings into a single large<br>

+    down to finding and freeing the array-of-strings since the last GC, and the<br>
+    (at most) 1,000 strings, one for each ReusableStreamDecode &quot;file&quot; object.<br>

+    pdfwrite - fix numerous font-related memory leaks<br>
+<br>
+    The pdfwrite device was originally written to do all its memory<br>
+    management via garbage collection, Unfortunately this leads to numerous<br>
+    memory leaks when using an interpreter which doesn't implement a<br>
+    garbage collecting memory model. Currently that's everything except<br>
+    the PostScript interpreter.<br>
+<br>
+    Many of these leaks cannot be exercised by anything except the<br>
+    PostScript interpreter (and the new pdfi interpreter) but I think some<br>
+    certainly could be.<br>
+<br>
+    Don't increment the 'subst' structure when copying a TrueType CIDFont,<br>
+    this leads to the structure never being freed.<br>
+<br>
+    The code to free the 'subst' CID when freeing a TrueType CIDFont was<br>
+    incorrect, leading to memory crashes (previously it was simply never<br>
+    executed, and leaked).<br>
+<br>
+    When increasing the size of the CIDMap entry for a TrueType CIDFont,<br>
+    free the memory used by the original map after copying the data and<br>
+    before overwriting the stored pointer.<br>
+<br>
+    When freeing a copied font, if the font is a TrueType CIDFont decrement<br>
+    the 'subst_CID_on_WMode' member so that it gets freed.<br>
+<br>
+    When freeing a copied font, use the copied glyph data 'data' member<br>
+    rather than the 'size' member to decide if we should free the data.<br>
+    Sometimes we allocate memory for a size of 0.<br>
+<br>
+    When freeing a copied font, if we created a names array for the glyphs<br>
+    we need to free the string copies of the names we created as well.<br>
+<br>
+    When freeing a copied font, if the CIDFMap entry has been created we<br>
+    must free that too.<br>
+<br>
+    When dropping a 'complete' font copy because we won't be using it, do<br>
+    not simply set the pointer to NULL but actually call code to free the<br>
+    copied font properly.<br>
+<br>
+    When freeing a pdfwrite copy of a base font, if the CIDSet member has<br>
+    been allocated we need to free it.<br>
+<br>
+    When adding to the pdfwrite font cache, if the glyph_usage and<br>
+    real_widths members have already been allocated we must free them before<br>
+    assigning newly allocated memory.<br>

+    Bug 702948: Ensure initial bitmap cache sizes are properly aligned<br>
+<br>
+    Now that the allocations from the bitmap cache are aligned to the platform's<br>
+    required alignment, see commit:<br>
+<br>
+    260c443bc14cdffa4d94e14c3a57e35bebee3a5b<br>
+<br>
+    We also want the initial size of the memory pool used by the cache to be<br>
+    &quot;aligned&quot;.<br>
+<br>
+    This is so that code that attempts to identify cache entries to evict by<br>
+    requesting a size equal to the entire size of cache memory pool doesn't get an<br>
+    unexpected failure, because we've rounded up that allocation request to a value<br>
+    larger than the entire size of the memory pool.<br>
+<br>
+    Because we don't expect an error to be possible at that point, a crash can<br>
+    occur.<br>
+<br>
+    Of the &quot;normal&quot; platforms we use, this only exhibits on Win32 because that is<br>
+    the only platform where the align_bitmap_mod we use is less than the<br>
+    obj_align_mod used for the memory managers.<br>

+<p>
+    Bug 702938: Allocating cached glyphs, account for alignment<br>
+<br>
+    For efficiency, the glyph cache allocates &quot;large&quot; blocks of memory into which<br>
+    it parcels out offsets for individual glyph cache bitmaps, as required.<br>
+<br>
+    Since cached glyphs are usually fairly small, and potentially can be short<br>
+    lived, this saves the overheads of &quot;full&quot; memory for every cached glyph.<br>
+<br>
+    Unfortunately, in calculating the offsets for the cached glyph, it was failing<br>
+    to account for the required alignment of the system. In any environment that<br>
+    strictly enforces aligned memory accesses, this will potentially cause a bus<br>
+    error.<br>
+<br>
+    In this case, it was switching the gs_glyph type to a 64 bit type that triggered<br>
+    the issue. But any changed to the contents of the cached_char struct could have<br>
+    resulted in it happening.<br>

+    Bug 702871: Fix GraphicsAlphaBits + Fill/Stroke issue.<br>
+<br>
+    When we flush the alphabuffer, mapped_start and mapped_height are<br>

+    non-zero. USUALLY mapped_start is set to non-zero too, but it can<br>

+<h2><a name="Version9.54.0"></a>Version 9.54.0 (2021-03-30)</h2>
+<p>The 9.54.0 release is a maintenance release, and also adds new functionality.
+<br>
 <p> Highlights in this release include:
 <ul>
 <li>
-<p>The 9.53.3 release is primarily maintenance.
-</li>
-<li>
-<p>Issues arose with 9.53.0/1/2 that prompted the release of a <code>.3</code> patch:
-<ul>
-<li>A crash (or silent, erroneous exit) on 64 bit Windows and other LLP64 type environments.</li>
-<li>What appears to be a compiler optimiser bug in 64 bit Windows builds with Visual Studio 2019</li>
-<li>A crash related to management of ICC profile objects</li>
-<li>A crash on SPARC hardware due to an alignment mismatch in the bitmap cache</li>
-<li>A parameter type mismatch that would cause Ghostscript to error out during initialisation,
-which affected 64 big, big endian architectures.</li>
-<li>An unexpected side effect of another change that prevented multithreaded rendering and background
-rendering from working correctly.</li>
-</ul>
-<p>Details of those can be found in the changelog.
+<p>Overprint simulation is now available to all output devices, allowing
+quality previewing/proofing of PostScript and PDF jobs that rely on overprint.
+See the <code>-dOverprint</code> option documentation in:
+<a href="Use.htm#Overprint">Overprint</a>
 </li>
 <li>
-<p>The most obvious change is the (re-)introduction of the patch level to the version number,
-this helps facilitate a revised policy on handling security related issues.
-<p>To clarify: in the event we decide to release a patch revision, it will <em>replace</em> the release
-with the previous patch number. Release notes, highlights and warnings will remain the same, except for the
-addition of whatever fix(es) prompted the patch.
+<p>The &quot;docxwrite&quot; device adds the ability to output to Microsoft Word
+&quot;docx&quot; format. See: <a href="VectorDevices.htm#DOCX">docxwrite</a>
 </li>
 <li>
-<p>Our efforts in code hygiene and maintainability continue.
-</li>
-<li>
-<p>We have added the capability to build with the Tesseract OCR engine. In such
-a build, new devices are available (pdfocr8/pdfocr24/pdfocr32) which render the
-output file to an image, OCR that image, and output the image "wrapped" up as a
-PDF file, with the OCR generated text information included as "invisible" text
-(in PDF terms, text rendering mode 3).
-<p>Due to some patches to the Tesseract sources that are required (integrated
-upstream, but awaiting release), time constraints, and the experimental nature
-of the feature, we only support including Tesseract from source, not linking to
-Tesseract shared libraries. Whether we add this capability will be largely
-dependant on community demand for the feature.
-<p>See <a href="https://www.ghostscript.com/ocr.html">Enabling OCR</a> for more details.
+<p>The pdfwrite device is now capable of using the Tesseract OCR engine when it is
+built into Ghostscript to improve searchability and copy and paste functionality when
+the input lacks the metadata for that purpose. See: <a href="VectorDevices.htm#UseOCR">UseOCR</a>
 </li>
 <li>
-<p>We have added Python bindings for the <code>gsapi</code> interface, can be found
-in <code>demos/python</code>. These are experimental, and we welcome feedback from
-interested developers.
+<p>Ghostscript/GhostPDL now includes a &quot;map text to black&quot;
+function, where text drawn by an input job (except when drawn using a
+Type 3 font) can be forced to draw in solid black. See:
+<a href="Use.htm#BlackText">BlackText</a>
 </li>
 <li>
-<p>For those integrating Ghostscript/GhostPDL via the <code>gsapi</code> interface, we
-have added new capabilities to that, specifically in terms of setting and interrogating
-device parameters. These, along with the existing interface calls, are documented in:
-<a href="API.htm">Ghostscript Interpreter API</a>
+<p>Ghostscript/GhostPDL now supports simple N-up imposition &quot;internally&quot;. See:
+<a href="Use.htm#NupControl">NupControl</a>
 </li>
 <li>
-<p><b>IMPORTANT:</b> In consultation with a representative of
-(<a href="http://www.openprinting.org">OpenPrinting</a>) it is
-our intention to deprecate and, in the not distant future, remove the
-OpenPrinting Vector/Raster Printer Drivers (that is, the <code>opvp</code>
-and <code>oprp</code> devices).
-<p> If you rely on either of these devices, <b><i>please</i></b> get in touch with
-us, so we can discuss your use case, and revise our plans accordingly.
+<p>Our efforts in code hygiene and maintainability continue.
 </li>
 <li>
-<p>IMPORTANT: We have forked LittleCMS2 into LittleCMS2mt (the "mt" indicating "multi-thread").
-LCMS2 is not thread safe and cannot be made thread safe without breaking the ABI. Our fork
-will be thread safe and include performance enhancements (these changes have all be been
-offered and rejected upstream). We will maintain compatibility between Ghostscript and LCMS2
-for a time, but not in perpetuity. If there is sufficient interest, our fork will be
-available as its own package separately from Ghostscript (and MuPDF).
+<p>The usual round of bug fixes, compatibility changes, and incremental improvements.
