+Fix for SEGV when PreserveHalftoneInfo=true is given as a pdfwrite
+option. Bug 688018.
+
+DETAILS:
+
+The initial problem was that the num_comp was not being looked at
+when HalftoneType 5 was written and if num_comp was 3, the 4th
+element of ht_ids[] was being used (UMR-wise). The solution to
+this was to only write the three halftones and to use the 'Green'
+halftone (arbitrarily) for Default.
+
+After fixing the SEGV, another problem surfaced because the object
+dictionary was not being terminated with the ">>".
+
+Since I suspected that the threshold_halftone writers were also
+broken I tested with 258-01.ps and found more problems. This
+code was also quite broken. Since the Threshold array is the
+stream data for HalftoneType 6 and 16, I changed this a lot to
+emit valid PDF.
+
+EXPECTED DIFFERENCES:
+
+None, since we don't set PreserveHalftoneInfo.</pre>

+Fix for 688019  /configurationerror in --setpagedevice--.  The PDF
+interpreter was incorrectly determining the size of the page.
+
+DETAILS:
+
+The test file specifies the following media box:
+
+/MediaBox [ 0 1080 1620 0 ]
+
+The PDF 1.6 specification says the following about media box rectangles:
+
+"3.8.4 Rectangles
+Rectangles are used to describe locations on a page and bounding boxes for a
+variety of objects, such as fonts. A rectangle is written as an array of four
+numbers giving the coordinates of a pair of diagonally opposite corners.
+Typically, the array takes the form
+[llx lly urx ury]
+specifying the lower-left x, lower-left y, upper-right x, and upper-right
+coordinates of the rectangle, in that order. The other two corners of the
+rectangle are then assumed to have coordinates (llx, ury) and (urx, lly).
+
+Note: Although rectangles are conventionally specified by their lower-left and
+upperright corners, it is acceptable to specify any two diagonally opposite
+corners. Applications that process PDF should be prepared to normalize such
+rectangles in situations where specific corners are required."
+
+The PDF interpreter was assuming that the MediaBox and the CropBox were
+in the 'typical' form.  This fix consists of creating a pair of procedures
+for converting rectangles into the typical form and then using the
+procedures.</pre>

+<pre>
+Conveys input tray selection info (/ManualFeed and /MediaPosition)
+setpagedevice requests to PCL devices. Fixes bug #687899.
+
+DETAILS
+
+1. The behavior of MediaPosition is changed significantly. Previously,
+   it was ignored (i.e. omitted altogether from setpd merging). Just
+   adding it to setpd merging would not be good - if set at the PS
+   level, then it would get checked for equality at the C level (by
+   zmatchmedia), and fail horribly if it didn't match. In accordance
+   with the PLRM3 text (it will be honored provided it can satisfy the
+   normal media matching), in the new version a mismatch simply adds a
+   .001 penalty to the matching score.
+
+2. The ljet4 device now contains ManualFeed and MediaPosition fields,
+   with appropriate putparams logic to set them.
+
+3. The MediaPosition and ManualFeed strings now create an ESC & l H
+   init string, according to the following logic. ManualFeed sends
+   ESC & l 2 H; if ManualFeed is false (or not set), then MediaPosition
+   0 sends ESC & l 5 H, and MediaPosition1 sends ESC & l 1 H. If none
+   of these are set, then no extra init string is generated.
+
+   Obviously, for this feature to be useful, there needs to be an
+InputAttributes dictionary in effect, for which the PageSize of
+positions 0 and 1 match the PageSize of the setpagedevice request.
+[Actually, if only ManualFeed is desired, then there is no need to
+fiddle with InputAttributes].
+
+   I think these changes bring our media selection more in line with
+what Adobe intended, and could be useful for embedded PS projects as
+well. I believe the risk of unwanted changes is small, but considering
+the delicacy of the setpagedevice logic, review and testing is
+warranted.</pre>

+<pre>
+pdfwrite : Implementing a viewer's resource memory control, part 1.
+
+DETAILS :
+
+This patch implements a primitive viewer's resource memory control.
+
+A new device parameter MaxViewerMemorySize specifies the number of bytes
+available for storing resources in the viewer's memory.
+This parameter defined almost for future extensions.
+
+Currently we distinguish two cases only : if the parameter is greater
+than 10000000 bytes, no resource control is being applied,
+i.e. pdfwrite assumes that the viewer can store all resources of entire document.
+Othervise pdfwrite assumes that the viewer can store resources of a single page.
+
+In the second case pdfwrite cleans internal resource caches after each page,
+so that any new resource usage will generate another resource instance
+in the output PDF file.
+
+To inform the viewer that the resources may be cleaned,
+we add a new key to a page contents stream dictionary.
+This is our extension to the PDF specification in order to control
+the resource management in the viewer.
+The new key name is /.CleanResources.
+Currently we provide only the value /All. It means that resources
+may be cleaned *after* ending the contents stream.
+
+In future on necessity we can split a page contents stream into substreams
+and provide a finer control by resource types with providing
+more values for the key /.CleanResources.
+
+When the viewer is informed with allowing to clean resources,
+it is not obliged to do so. Further resource appearences simply replace
+old ones, if they have same resource name.
+Actually now this happens only with font and CID font resources.
+Other resource instances may persist in the viewer's memory until
+the viewer's garbager frees them when they are not
+referred from resource tree dictionaries.
+
+The resource control is mainly intended for ps2write.
+An implementation of the viewer's side (in opdfread.ps) will be a separate patch.
+
+Note that when a resource control is being applied,
+the output document size may increase significantly.
+
+Currently we don't add MaxViewerMemorySize to user's documentation,
+because it depends on another undocumenmted parameter ForOPDFRead
+through the ResourcesBeforeUsage flag. First we need to take a decision
+whether ps2write will become a new Ghostscript device or it stays a tool
+represented with a script. The latter gives more flexibility to users
+about composing the header procsets of the generated Postscript document.

+ps2write : Convert shadings into a clipped image (continued 4).
+
+DETAILS :
+
+Implement a downsampling when converting a shading into bitmap.
+
+1. A new device parameter MaxShadingBitmapSize controls the downsampling.
+   Shadings, which give a (uncompressed) bitmap over the specified size,
+   will be scaled down.
+
+2. The scaling algorithm goes to gdevpdfd.c .
+   It appears pretty tricky because we need to setup a device with a smaller
+   resolution than the target device. Due to that we need to scale paths and colors,
+   which are represented in the device space. The function scale_path works for it.
+
+3. The scaling creates a local copy of a device color (which handles the shading)
+   and scales the color. Since we can't access further spatial transformations of the color,
+   we apply some unusual operation : multiply matrices in the reverse order
+   than usual 'concat' does. This makes some useful equations to be soluble
+   due to the offset is being scaled as well.
+
+4. A code portion was copied from gx_default_fill_path
+   (see comment in code).
+   We're unhappy about uncomfortable code structurization.
+
+5. path_scale is implemented with floating point for a debug purpose,
+   but in production we use only integers being a power of 2.
+
+6. There is a problem with
+   <</PatternImagemask false /MaxClipPathSize 12000 /MaxShadingBitmapSize 100000000>>
+   The problem happens when dividing the scaled bitmap in smaller ones
+   due to clip path overflow. This mode to be debugged separately.
+   For now set either smaller bitmap size of bigger clip path size.
+   Default settings work fine for most cases.
+
+EXPECTED DIFFERENCES :
+
+None.</pre>

+ps2write : Implementing the RotatePages and the FitPages options.
+
+DETAILS :
+
+This is a further improvement of the last patch.
+
+When RotatePages is defined in the target device,
+the opdfread procset rotates pages for a better fitting
+into the page size.
+
+When FitPages is defined in the target device,
+the opdfread procset scales pages for a better fitting
+into the page size.
+
+Note thet if both options are specified,
+the procset first rotates and then scales a page.
+
+No rotations happen if a page fits with no rotation or
+if a rotation doesn't improve the fitting.
+
+Rather the RotatePages option looks similar to
+the distiller parameter AutoRotatePages,
+it affects a PS interpreter in the target printer
+rather than the distiller in the ps2write host.
+
+Thge implementation accounts /.HWMargins,
+which is Ghostscript specific feature.
+It is useful when the printer embeds Ghostscript.
+
+Since now the options may appear either in systemdict,
+or in userdict, or in globaldict of the printer.

+<blockquote>
+<pre>
+Fix for 687434, 687835, and 687982.  These reports are  /vmerror in
+--eofill-- or --fill--.  They are caused by the pattern accumulation
+device trying to allocate excessively large buffers.
 
 DETAILS:
 
-Only the call in getenv() is active; the one in gp_init() is not used.
+The pattern accumulation device allocates an image buffer for holding
+patterns.  The size of the pattern buffer (prior to this fix) is based
+upon the bounding box specified with the pattern.  For the problem files,
+the pattern bounding boxes are excessively large.  The vmerrors are the
+result.
+
+This fix consists of comparing the pattern bounding boxes to the size
+of the page to be imaged.  (All of the files have bounding boxes which
+are much larger than the page.)  We determine which part of the pattern
+will actually be used and limit the pattern accumulation to the area
+which is needed.  Most of this fix consists of stepping the pattern to
+check the intersection between the pattern and the page.  The major
+complication in this process is simply due to the arbitrary transform
+matrix which can be applied between the coordinate space used to define
+the pattern and the coordinate frame of the output page.
+
+This fix significantly reduces the buffer sizes required for these
+test files.  However it is still possible for a pattern buffer to
+exceed available memory.  It is possible to create a solution using some
+version of a band list.  However my estimate on that task keeps getting
+larger as I look at the details.</pre>

+((1 << 2) * 8 - 9 - 2) : (10))) - 1))) >> (((((1 << 2) * 8 - 9 - 2) < (10)) ? ((1 << 2) * 8 - 9 - 2) :
+(10))))) << (8 - ((((1 << 2) * 8 - 9 - 2) < (10)) ? ((1 << 2) * 8 - 9 - 2) : (10)))) :
+(((pcrd->caches.EncodeABC[0].fixeds.ints.values)
+[((tabc[0]) >> ((((1 << 2) * 8 - 9 - 2) < (10)) ? ((1 << 2) * 8 - 9 - 2) : (10)))] +
+(frac)(((long)((pcrd->caches.EncodeABC[0].fixeds.ints.values)

+
+(the other 2 ones replace "[0]" with "[1]" and "[2]").
+
+We gues that MSVC8 is not enough intelligent to prove that the static (sub)expression
+((((1 << 2) * 8 - 9 - 2) < (10)) ? ((1 << 2) * 8 - 9 - 2) : (10))
+is always within the interval [0, 10] and therefore it claims a possible error.
+This patch replaces it with a dynamic constant 's',
+so that the warning doesn't appear.
+In any case we believe that the huge expression above isn't a
+good coding style since humans need to read the code sometimes.
+
+For ones who wish a further simplification,
+we're happy to bring some useful definitions :
+
+XXX = ((((1 << 2) * 8 - 9 - 2) < (10)) ? ((1 << 2) * 8 - 9 - 2) : (10))
+YYY = ((int)(tabc[0]) & ((1 << XXX) - 1))
+ZZZ = ((tabc[0]) >> XXX)
+TTT = (pcrd->caches.EncodeABC[0].fixeds.ints.values)
+
+Using them the expression reduces to :

+Fix for 687696 PDF 1.4 transparency can use large chunks of memory.
+Prior to this fix the handling of PDF 1.4 transparency features used one
+or more full size image buffers.  With high resolutions and large images,
+these buffers can be multiple gigabytes.  As a result, we were not able
+to handle these files.
 
 DETAILS:
 
-This is a fairly minor modification to the gs MSVC makefiles, but it did
-require changing our jasper version (that had accumulated many changes)
-to hook in the correct jas_config***.h file and to avoid using windows.h
-(so we can build with /Za). See the jasper svn for details of the changes.
+PDF 1.4 transparency is handled by a device which is inserted into the
+device chain.  Prior to this fix, this device was via the 'device filter'
+logic.  With this fix, the PDF 1.4 transparency device is inserted via
+the compositor device mechanism.  This change was made since the device
+filter logic did not allow other devices to control where the PDF 1.4
+transparency device is placed in the device chain.  There is a device
+proc which implements the create compositor action.  This allows more
+control than the device filter logic.
 
-EXPECTED DIFFERENCES:
+The first step in this fix was to convert the PDF 1.4 transparency
+logic to use the create compositor mechanism.  For situations in which
+the clist logic is not being used, the PDF 1.4 transparency device is
+created and placed in the same location in the device chain as it was put
+by the device filter logic.  In this situation, there is very little
+logical difference in the operation of the PDF 1.4 transparency.
+
+For situations in which the clist is used, there are two PDF 1.4
+compositing devices created.  There is one device before the clist when the
+clist is being written.  There is a second device after the clist when
+the clist data is being read.
+
+The device before the clist serves two purposes, it provides a means for
+implementing the process color model for the PDF 1.4 compositing.  (The
+PDF 1.4 compositing may used a different process color model from the output
+device.)  Thus this device has color_info and encode/decode color procs
+which match the PDF 1.4 blending color space.  This device also ensures
+that the PDF 1.4 blending parameters (blend mode, shape, opacity, etc.)
+are passed through the clist to the second PDF 1.4 device.
+
+The second PDF 1.4 device (the one when the clist is being read) is the
+same PDF 1.4 compositing device which is used when the clist is not being
+used.  This is the device which does the blending operations.  Since the
+device is after the clist, the buffers that it needs are the size of a
+single band instead of the full page.  This device is placed prior to
+the memory device which is used for drawing the raster data.
+
+Two changes were made in the 'create compositor' logic.  The imager state
+was being passed as a 'const'.  It is no longer const since the PDF 1.4
+transparency compositing changes the cmap procs in the imager state to not
+use transfer functions during color calculations.  The transfer functions
+are applied later (and the cmap procs restored) when blended image data
+is output from the PDF 1.4 compositing buffers.
+
+The second change to the create compositor logic is the addition of two
+more procedures to the gs_composite_type_t.procs list.  These procedures
+are used by the clist device create compositor routines.  The first
+is used to create the PDF 1.4 clist write device.  The second saves and
+restores the color_info field for the clist device (see below).
+
+Default versions of the added gs_composite_t.procs were also added for
+use by the other compositor devices.  The defaults are no-ops.
 
-none. (we didn't have any PDF 1.5 files with JPEG2000 images in the
-comparefiles).</pre>
-<p>[src/msvc32.mak 1.67, src/winlib.mak 1.24]</p>
+The clist logic has a few changes.  Since the PDF 1.4 compositor device
+may use a different process color model from the output device, the number
+of colorants and the depth (bits per pixel) can be different for the PDF
+1.4 compositor and the output device.  Thus changes were needed in parts
+of the clist logic which assumed that these items were constant during the
+processing of the clist.  An extra field was added to the device halftone
+to indicate the number of colorants in effect when the device halftone was
+created.  This data is included when the halftone is serialized for the
+clist.  (Fortunately the PDF 1.4 compositing does not use halftones or
+transfer functions.  So the device halftones and transfer functions do
+not need to be changed when the PDF 1.4 compositor is installed.)
+
+As previously mentioned the create compositor procedures for the clist
+writer and reader now call a couple of compositor specific routines.  These
+allow the compositor to implement actions related to the clist device.
+(The PDF 1.4 compositor uses these routines to create the 'write clist'
+PDF 1.4 compositor and to save and restore the clist device color info.
+The color_info field of the clist device is changed to match the process
+color model of the PDF 1.4 compositor while the PDF 1.4 compositor is active.
+
+A additional device parameter (PageUsesTransparency) was added.  This
+parameter is sent by the PDF interpreter to indicate if PDF 1.4 transparency
+will be used on the page.  The banding/no banding decision and the size
+of a band includes an estimate of the size of the PDF 1.4 blending buffers
+if this parameter is true.  Note:  The estimate of the size of the
+blending buffers is not exact since this calculation is made before the
+actual number of buffers, the number of blending colors and alpha channels
+is known.  Fixed values are used for the estimated buffer size.  This is
+still much better than the pervious situation, in which the only the
+output raster size was being used.  The blending buffers can easily be
+30 or more times larger than the raster buffer.
+
+This fix also involves the removal of the PDF 1.4 'marking' devices.
+The marking devices were used to actually implement the pixel marking.
+The marking devices were created at the start of each high level drawing
+operation and deleted after the completion of the operation.  The marking
+device action has been merged into the primary PDF 1.4 compositing device.
+This change eliminates some device creation overhead.  The overhead would
+have been worse since most information about high level drawing operations
+is not passed through the clist.  As a result it would have been necessary
+to create marking devices for each low level operations.
+
+The following issues are not included in this fix but need to be considered.
+
+1)  The device filter logic is no longer used.  It may be desired to remove
+this logic.
+
+2)  We currently have a 'create_compositor' device proc.  However there
+is not a 'delete_compositor' device proc.  As a result, compositor devices
+can stay in the device chain even when they are no longer needed.  The
+current fix turns the PDF 1.4 compositor into a 'forwarding' device.  This
+is the same method used by the overprint compositor device.  I do not like
+leaving these devices since there is some extra overhead and there may be
+possible side effects.  (Testing has been done to try to find side effects
+and none has been found with the current code.)
+
+3)  This change only affects devices which can use the clist logic.  This
+excludes the 'high' level devices.  These include the 'display', 'x11',
+and 'pdfwrite' devices.  Thus these device will continue to use a full
+image buffer.  It is possible to extend this fix to use a clist device
+for the PDF 1.4 device for these devices.</pre>

+
+DETAILS:
+Microsoft Visual Studio .NET 2003 with Windows Server 2003 DDK,
+or Microsoft Visual Studio 8 (.NET 2005 beta) are required
+to compile for 64-bits.
+
+Dialog boxes return type INT_PTR not BOOL.
+
+Install to the "Program Files" directory as default,
+instead of c:\gs.  This allows 32-bit and 64-bit
+versions to be installed in separate locations.
+For 32-bit GS on 32-bit Windows, "c:\Program Files\gs"
+For 32-bit GS on 64-bit Windows, "c:\Program Files (x86)\gs"
+For 64-bit GS on 64-bit Windows, "c:\Program Files\gs"
+The " (x86)" is added by Windows when a 32-bit program asks
+for the "Program Files" folder on 64-bit Windows.
+Other languages will translate "Program Files".
+
+The programs still have "32" in their names: gswin32c.exe,
+gswin32.exe and gsdll32.dll.  They are distinguished from
+the 32-bit versions by their install location.
+This avoids changes to many batch files.
+
+The registry entries written by the installer do not
+conflict between 32 and 64-bit.
+For 32 on 32, or 64 on 64, the location is
+  HKLM\Software\AFPL Ghostscript\N.NN
+For 32 on 64, Windows adds "WoW6432Node\" to make it
+  HKLM\Software\Wow6432Node\AFPL Ghostscript\N.NN
+
+If the "Program Files" folder has a " (x86)" suffix,
+this is used as a suffix on the Start Menu items.  This
+allows 32-bit and 64-bit GS to be installed without
+conflict.  The start menu item for 32-bit GS on 64-bit
+Windows is "Ghostscript N.NN (x86)".
+
+Building 64-bit GS on 32-bit Windows can be done
+by the usual method - either execute genconf.exe on
+a 64-bit platform or hand edit arch.h.
+
+A separate patch will fix the display device DisplayHandle
+parameter which is currently truncated to 32-bits.
+
+There is a warning from the linker about exports being
+defined multiple ways.  This is not a problem with the
+32-bit compile.  This is due to the C code
+specifying export and the module definition file
+also specifying the export.  Removing the function
+names from the module definition file would make the
+warning message go away, but may affect 32-bit compiles.</pre>

+Change display device parameter DisplayHandle from an integer
+to a string, to add support for 64-bit platforms.
+
+DETAILS:
+The display device passes a (void *) handle to callback functions.
+The handle is set before the device is opened, and attempting to
+change it afterwards is an error.
+The handle may be used by the caller to identify an instance of
+the display device, for example it may point to the display instance
+object in the caller.
+This handle was set using a PostScript integer which is 32-bits long,
+typically with -dDisplayHandle.
+The existing code will not work correctly on 64-bit architectures.
+
+The display device is changed to return a string as the
+DisplayHandle parameter.
+Previously the handle would be set using -dDisplayHandle=1234.
+The changed code allows it to be passed as
+ -dDisplayHandle=1234
+ -sDisplayHandle=1234
+ -sDisplayHandle=10#1234
+ -sDisplayHandle=16#04d2
+This should be backward compatible, since users of the
+display device will most likely only set the DisplayHandle,
+not read its value.
+

-Add a platform-specific JASPERCFLAGS makefile variable to assist with
-proper compilation of the jasper jpeg2k library. Set this variable
-correctly in the autoconf build.
+Eliminate a performance problem when a TT font has a large 'loca' table.
+A fix for 687889 used .sort on the 'loca' table but this takes a long
+time if the table is large. Only run the .sort if the table is out of
+order which is rare since the TT font spec requires an in-order table.
+Bug 687968.
 
 DETAILS:
 
-The jasper library natively supports building under both autoconf+cc and
-MSVC, but expects a preprocessor define to be set to distinguish the
-two. While we do carefully construct a special JAS_CC for compiling the
-jasper source into Ghostscript, as with all the other 3rd party
-libraries, there is only a facility to set special CFLAGS globally.
+Apparently our conversion of the 'japan.ps' file creates a TT font with
+a loca table that has 20458 entries (even though the original font
+in japan.ps didn't have that many). This is needed because there are
+many glyphs that are not present, but we need loca table slots that
+represent the missing glyphs (same starting offset as next glyph).
+
+The time was being spent doing the '{ lt } .sort' of the array  :-(
+
+I added logic that checked the order as the loca table was converted
+to an array so that the .sort could be skipped as long as the table is
+in order (which it *should* be for a valid TT font). After this change,
+the HEAD time is 1.16 CPU seconds versus 1.08 seconds for gs8.50.
+(with the .sort, the time was 257 seconds).
+
+I suppose that we could optimize the .sort (put it into 'C') but
+for now I'll just avoid it most of the time.
+
+Note that since the .sort has a procedure callout for the ordering test,
+it might not speed up that much in 'C'. That's the other reason that it
+is worthwhile to avoid the .sort when possible.</pre>

+pdfwrite : Use character codes instead CIDs when creating a ToUnicode CMap.
+
+DETAILS :
+
+Bug 687954 "copy and pasting asian text problems".
+
+The problem depends on what a Postscript printer driver
+puts into the GlyphNames2Unicode table.
+
+GlyphNames2Unicode is an undocumented feature, which PScript5.dll uses to
+communicate with Adobe Distiller. A long ago from its name
+we concluded that it maps character names to Unicode, and it was
+confirmed with multiple documents. Now we got a document
+(the test case of the bug 687954), which uses character codes instead CIDs,
+(CIDs are usually interpreted as "glyph names" in the case of CID fonts).
+In the test document CIDs are not equal to character codes due to the embedded CMap
+named WinCharSetFFFF-H2. We did not notice this problem before
+due to most old documents from PScript5.dll use an identity CMap WinCharSetFFFF-H,
+
+Now we change Ghostscript with using character codes instead CIDs
+as keys to GlyphNames2Unicode. We have no technology for a regression test
+of the related behavior. We will pass this revision to users in order to study
+consequences of this patch from users' responses.

+This is clearly a questionable TT font since the Apple TT font reference
+manual clearly states that the length of glyphs can be inferred from
+the difference in successive offsets.
+
+Note that the PostScript code only needs to deal with the sorted 'locatable'
+in order to decide where to split the glyf strings in the sfnts array
+(in the .dividesfnts proc). Otherwise the PostScript code doesn't care.
+
+If the .dividesfnts uses a sorted locatable, but doesn't replace the 'loca'
+table written into the sfnts, then the VMerror occurs because the C code
+in 'default_get_outline' calculated the glyph_length for the gs_alloc
+using loca table entries that might be out of order.
+
+In order to effect the entire fix, I sorted the 'locatable' for the PS
+code in .dividesfnts as well as creating a new 'len_glyphs' array in
+the gs_type42_data structure that holds the actual glyph lengths.
+The glyph lengths are calculated once when the font is initialized in
+gs_type42_font_init. If the 'loca' table is in order, then nothing
+changes, but if it is out of order, we get the lengths by finding the
+next higher glyph offset anywhere in the loca table.
+
+These changes let the file run and show the same glyphs as Adobe Acrobat

+
+DETAILS :
+
+This patch defines overall logic and data exchange for converting images to
+ProcessColorModel color space. For a while, the real convertion is stubbed
+with conversion into a bitmask (a 1 bit per sample image).
+
+1. When pdf_begin_typed_image calls pdf_color_space,
+a failure means that the image can't represent in the output PDF.
+Then we setg up a n image color conversion filter with
+psdf_setup_image_colors_filter.
+
+2. The function psdf_setup_image_colors_filter currently is stubbed
+with etting up the "image_to_mask" filter instead a general color conversion filter.
+Implementing the general filter will be the next step.
+
+3. When conversion happens, pdf_begin_typed_image writes
+a ProcessColorModel colore space instead the image color space.
+Currently it is stubbed with gs_color_space_index_DeviceGray
+to comply with the stub in psdf_setup_image_colors_filter.
+
+4. Multiple bugs (mainly the order of bits in the stream,
+and row to tyte alignment) have bin fixed in s_image_to_mask_process.
+
+5. We continue to use pdev->OrderResources as a general switch
+for the ps2write mode, rather it's not fully correct.

 DETAILS :
 
-Bug 687810 "/invalidfont in --@0x1e36c".
+Since CIEBased is not a PDF 1.2 object, we need to convert it somehow.
 
-Note that the error message appears some misleading due to sbx, sby is placed in ostack
-for type42_finish. Rather we could fix it in this particular case in type42_finish,
-a complete fix appears too complicated. So for now leave it as it is.
+One possible way is to write CIEBased into PDF.
+We do not choose this way because (1) it will generate an invalid PDF
+so that we'll not be able to verify the output with PDF readers;
+(2) we have no code for writing a CIEBased color space to PDF or Postscript,
+but we do have one for ICCBased.
+
+Another way is to write ICCBased into the ps2write output
+and to implement a parsing of ICC profile in opdfread.ps .
+We prefer this way since a part of this algorithm (an ICC writer)
+already presents in Ghostscript.
+
+Strongly saying, a PDF with ICCBased is not a valid PDF 1.2 document.
+But as we noticed before, Adobe PDF viewers simply ignore
+pdf level from the document header. So we'll be able to view it
+as it is or after a small modification of the header.
+
+We continue to use the flag OrderResources as a general switch for
+ps2write mode. Doing so because we still have no
+a perfect decision about the list and logics of configuration options.
+Later we'll need to bring more order to this field.
+Possibly writing a "restricted PDF1.3" would be better that
+writing an "extended PDF 1.2".
+
+By the way, pdfwrite appears to have a rudimentary branch
+pdf_convert_cie_to_lab, which currently is a stub,
+which always fails. We think that this conversion isn't possible
+in general due to Lab restricts with a very special class of
+transformations. So lakely this branch will never be implemented
+and it must always fail.
+
+Please note that with this patch ps2write successfully converts
+a smaller class of input files then before it,
+because the writer becomes inconsistent with
+the reader coded in opdfread.ps . But we do need this step
+in the develoipment technology. Actually the files outside the class
+were converted into a too long PDF.

+After the compression chooser is closed, the old code

+
+This patch generalizes the code with closing all filters in the chain

-2. Improved vdtrace commands for a disabled hinting.
+BTW, we're unappy of all this stuff,

+
+DETAILS :

+The mask is being generated with a new 4th alternative stream of pdf_image_writer.
+Note it's a completely different way than image type 3.
+
+1. Fixed a typo in 'pdf_image_writer_num_alt_streams'.
+
+2. pdf_image_writer_num_alt_streams is increased to 4,
+   and added pdf_image_writer::pres_mask.

+4. Factored out pdf_begin_image_data_decoded (an equivalent code change).
+
+5. Factored out pdf_end_and_do_image (an equivalent code change).
+
+6. pdf_begin_write_image now may be called at 2nd time to set up the 4th alternative stream.
+   The branches for mask==true work for that.
+
+7. Implenented a new filter image_to_mask for converting a colored
+   image with MaskColors into an imagemask (gdevpsds.h, gdevpsds.c).
+
+8. psdf_setup_image_to_mask_filter helps for (7). (gdevpsdf.h, gdevpsdi.c)/
+
+9. pdf_begin_typed_image now creates 4th alternative image stream with

+   "if (pic->type->index == 4 && pdev->CompatibilityLevel < 1.3)".
+   See comment in there.
+
+10. pdf_image_end_image_data handles the 4th stream

+
+2. In gdev_pdf_fill_path, fixed the grouping of clip paths for all

+3. In gdev_pdf_fill_path, used the shading BBox to minimize

+
+4. In gdevpdfp.c allowed CompatibilityLevel=1.1 .
+Now this is done mainly for debug purpose,
+but likely we'll use it in ps2write when the target doesn't handle TT fonts.
+
+5. The new function gx_dc_pattern2_get_bbox works for (3).
+
+6. The function shade_bbox_transform2fixed has been renamed into
+gx_dc_pattern2_shade_bbox_transform2fixed with making its scope bigger
+to work for (5). It has been moved into gsptype2.c,
+which is mode fundamental than gxshade.c .

+We would like to do more cleanup with replacing it with
+gx_dc_pattern2_get_bbox, but currently we delay that to simplify this patch.
+
+7. Introduced a new field patch_curve_t::straight to know whether a patch

+8. mesh_triangle now passes the coverage area.
+An auxiliary function mesh_triangle_rec is factored out for that.

+Implementing a convertion of a shading to a raster image for high level devices.
+
+DETAILS :
+
+If a high level device can't handle a shading,
+it is being converted to a raster image.
+
+This patch implements it only in OrderResources mode.
+A generalization to "normal" mode will be done in a separate patch.
+
+The generated bitmap sometimes appears too big since it
+doesn't accout a bbox of a real shading coverage.
+An optimization is coming soon.
+
+1.The device virtual function pattern_manage now handles
+a new request pattern_manage__shading_area.
+If it returns 1, the graphics library will pass
+the shading area as a special call to fill_path,
+with passing NULL images\r state and NULL clipping path.
+Such call immediately follows pattern_manage(...., pattern_manage__shading_area).
+Currently it goes only to a special converter device (see below),
+other devices and the default implementation return 0
+for pattern_manage(...., pattern_manage__shading_area).
+
+2. A new local type pdf_lcvd_t implements a subclass for
+memory device, which is used especially for converting shadings
+to raster image. It is defined locally in pdfwrite.
+The subcalss redefines 4 device methods :
+
+2.1. fill_rectangle with shifting the device space.
+It is used to mapo the shading and its paths to the image coordinate system.
+
+2.2. get_clipping_box returns the target clipping box,
+to deceive a cut-off condition in the shading algorythm.
+
+2.3. pattern_manage returns 1 for pattern_manage__shading_area.
+
+2.4. fill_path is used only for handling the shading area.
+It sets a clipping when instantiating the bitmap.
+
+3. gdev_pdf_fill_path implements the convertion with (2).
+
+4. gs_shading_fill_path doesn't set up a clipper device
+when it works with the shading convertion device.
+Instead that the clipping path is being passed through (2.4).
+
+5,. patch_fill in gxshade6.c checks if the devices needs the
+shading area, and if so, passes the area throuhg the special call to
+fill_path.
+
+EXPECTED DIFFERENCES :
+
+None.</pre>

+It is algorithmically equivalent for other invocations.
+
+1. The patch http://ghostscript.com/pipermail/gs-cvs/2005-January/005163.html
+broke the OrderResources mode. Fixed in gdevpdfu.c .
+This is another fix to that.

+Fix for an infinite loop in a PDF file that uses Patterns. Bug 687802
+for customer #850.
+
+DETAILS:
+
+The problem was that the DefaultQstate used when making a Pattern
+was the device *BEFORE* the pdf14 device filter was inserted as
+the device. If the underlying device had a different 'depth' than
+the PDF14 device, the pattern cache lookup would always fail which
+would then cause the fill to return e_RemapColor and perform the
+PaintProc again. The 'depth' comparison is in gsptype1.c in the
+gx_pattern_cache_lookup	function.
+
+The fix is to set the DefaultQstate *AFTER* the pushpdf14devicefilter
+is performed (and of course also reset it after popdevicefilter
+is done).
+
+Expected Differences:
+
+None (we didn't have any regression tests that use Patterns in pages
+with transparency). In fact, we only had two pages with ANY transparency:
+ai2.pdf and dina3_watermark.pdf.</pre>

+5. A new device parameter HaveCIDSystem is defined to the pdfwrite device

+
+DETAILS :

+Bug 645316 Quark EPS file with CID fonts
+Bug 687845 text doesn't appear from embedded japanese font
+Bug 687847 text missing from CIDFont
+
+From PLRM3 section 5.11 page 389 :
+
+Under special conditions, a CID can be used when the descendant is a Type 3
+base font. The font's BuildGlyph or BuildChar procedure is invoked to render a
+character whose code is the last byte originally extracted from the show string.
+If this procedure executes setfont to establish a CIDFont as the current font
+and then executes a show operation on a string consisting of just that character
+code, the code is ignored; instead, the CID determined by the earlier CMap
+mapping is used to look up the glyph in the CIDFont. This special case exists
+for compatibility with applications that substitute Type 3 fonts for base fonts
+in a composite font hierarchy to achieve certain special effects.
+
+This patch fixes the PS interpreter,
+but pdfwrite processing needs a separate improvement,

+Fix : A hang adding over 256 glyphs for a stable font copy.
+
+DETAILS :
+
+Bug 687816 "Hang in named_glyph_slot_hashed".
+
+1. Added gs_copied_font_data_s::num_glyphs to monitor
+the current number of glyphs in a stable font copy (gxfcopy.c).
+
+2. copy_glyph_data maintains gs_copied_font_data_s::num_glyphs (gxfcopy.c).
+
+3. gs_copied_can_copy_glyphs checks whether the preallocated
+size of the glyphs array doesn't exceed (gxfcopy.c).
+
+4. copy_glyph_data is fixed to return error code when
+trying to add a glyph over the preallocated size of the glyphs array (gxfcopy.c).
+
+5. pdf_obtain_font_resource_encoded is changed to handle the case when
+new glyphs overflow the font copy (gdevpdtt.c).
+
+The changes above fix the bug, but we also provide an additional optimization
+with GLYPHS_SIZE_IS_PRIME 1 (gxfcopy.c):
+
+6. Preallocate at least 257 ghyphs rather than 256 ones by the old code;
+This coners a font of 256 glyphs and 1 .notdef  (gxfcopy.c).
+(Well, that could fix the hang in the sample case of the bug 687816,
+but generally there exist other cases due to the font merging,
+which require the changes 1-5 above.
+
+7. Use primes numbers for the size of glyphs array instead powers of 2
+against unprodactive expense of RAM (gxfcopy.c).
+
+When the changes 5 was done, a regression happened with tpc2.ps :
+pdfwrite generated an incorrect PDF. To fix that, we forced to do more changes :
+
+8. pdf_register_charproc_font recieved a gs_id of the PS font instead
+the PDF object id. It caused a problem with multiple muster fonts,
+because MM instances have same id as the MM font.
+pdf_encode_string is changed to pass a correct resource id (gdevpdte.c),
+
+9. Since tpc2.ps generates hundreds of MM font instances, the field
+pdf_font_resource_s::u.s.used_fonts may not have a staticly defined size.
+replaced with a dynamicly allocated array (gdevpdtf.h, gdevpdte.c).
+
+10. Garbager descriptor for pdf_font_resource_s is changed to maintain (9).
+
+11. A new function pdf_find_resource_by_resource_id is defined for
+the correct implementation of pdf_used_charproc_fonts (gdevpdfu.c).
+
+After it another tpc2.ps regression persisted : the character 'y'
+dissapperaed in some words. The following changes are done to fix that :
+
+12. Improved thge hash function in pdf_add_subset_prefix (gdevpdtb.c).
+
+13. Defined FINE_GLYPH_USAGE 1 for a better precision of the font subset,
+in the case when a PS interpreter callout happens fro CDevProc or for a Type 3 BuildChar
+(gdevpdfx.h, gdevpdte.c). Currently it works for non-CID fonts only.
+
+14. Improved the diagnistics for the missed glyph in a Type 1 font (gs_type1.ps).
+
+Actually the last regression reflects another problem in the PDF interpreter,
+which is described in a new bug 687856.
+
+EXPECTED DIFFERENCES :
+
+pdfwrite :
+
+test-setweightvector.ps
+tpc2.ps
+
+The distilled tpc2.ps gets 1 progression and 1 regression.
+The progression is the glyph width. The regression is an ununiform
+stem width while rendering the PDF due to problem in the PDF interpreter.
+We describe that problem in the new bug 687857.</pre>

+<pre>
+Fix for SEGV when PreserveHalftoneInfo=true is given as a pdfwrite
+option. Bug 688018.
+
+DETAILS:
+
+The initial problem was that the num_comp was not being looked at
+when HalftoneType 5 was written and if num_comp was 3, the 4th
+element of ht_ids[] was being used (UMR-wise). The solution to
+this was to only write the three halftones and to use the 'Green'
+halftone (arbitrarily) for Default.
+
+After fixing the SEGV, another problem surfaced because the object
+dictionary was not being terminated with the ">>".
+
+Since I suspected that the threshold_halftone writers were also
+broken I tested with 258-01.ps and found more problems. This
+code was also quite broken. Since the Threshold array is the
+stream data for HalftoneType 6 and 16, I changed this a lot to
+emit valid PDF.
+
+EXPECTED DIFFERENCES:
+
+None, since we don't set PreserveHalftoneInfo.</pre>

+<pre>
+Fix for 688019  /configurationerror in --setpagedevice--.  The PDF
+interpreter was incorrectly determining the size of the page.
+
+DETAILS:
+
+The test file specifies the following media box:
+
+/MediaBox [ 0 1080 1620 0 ]
+
+The PDF 1.6 specification says the following about media box rectangles:
+
+"3.8.4 Rectangles
+Rectangles are used to describe locations on a page and bounding boxes for a
+variety of objects, such as fonts. A rectangle is written as an array of four
+numbers giving the coordinates of a pair of diagonally opposite corners.
+Typically, the array takes the form
+[llx lly urx ury]
+specifying the lower-left x, lower-left y, upper-right x, and upper-right
+coordinates of the rectangle, in that order. The other two corners of the
+rectangle are then assumed to have coordinates (llx, ury) and (urx, lly).
+
+Note: Although rectangles are conventionally specified by their lower-left and
+upperright corners, it is acceptable to specify any two diagonally opposite
+corners. Applications that process PDF should be prepared to normalize such
+rectangles in situations where specific corners are required."
+
+The PDF interpreter was assuming that the MediaBox and the CropBox were
+in the 'typical' form.  This fix consists of creating a pair of procedures
+for converting rectangles into the typical form and then using the
+procedures.</pre>

+<pre>
+Conveys input tray selection info (/ManualFeed and /MediaPosition)
+setpagedevice requests to PCL devices. Fixes bug #687899.
+
+DETAILS
+
+1. The behavior of MediaPosition is changed significantly. Previously,
+   it was ignored (i.e. omitted altogether from setpd merging). Just
+   adding it to setpd merging would not be good - if set at the PS
+   level, then it would get checked for equality at the C level (by
+   zmatchmedia), and fail horribly if it didn't match. In accordance
+   with the PLRM3 text (it will be honored provided it can satisfy the
+   normal media matching), in the new version a mismatch simply adds a
+   .001 penalty to the matching score.
+
+2. The ljet4 device now contains ManualFeed and MediaPosition fields,
+   with appropriate putparams logic to set them.
+
+3. The MediaPosition and ManualFeed strings now create an ESC & l H
+   init string, according to the following logic. ManualFeed sends
+   ESC & l 2 H; if ManualFeed is false (or not set), then MediaPosition
+   0 sends ESC & l 5 H, and MediaPosition1 sends ESC & l 1 H. If none
+   of these are set, then no extra init string is generated.
+
+   Obviously, for this feature to be useful, there needs to be an
+InputAttributes dictionary in effect, for which the PageSize of
+positions 0 and 1 match the PageSize of the setpagedevice request.
+[Actually, if only ManualFeed is desired, then there is no need to
+fiddle with InputAttributes].
+
+   I think these changes bring our media selection more in line with
+what Adobe intended, and could be useful for embedded PS projects as
+well. I believe the risk of unwanted changes is small, but considering
+the delicacy of the setpagedevice logic, review and testing is
+warranted.</pre>

+<pre>
+pdfwrite : Implementing a viewer's resource memory control, part 1.
+
+DETAILS :
+
+This patch implements a primitive viewer's resource memory control.
+
+A new device parameter MaxViewerMemorySize specifies the number of bytes
+available for storing resources in the viewer's memory.
+This parameter defined almost for future extensions.
+
+Currently we distinguish two cases only : if the parameter is greater
+than 10000000 bytes, no resource control is being applied,
+i.e. pdfwrite assumes that the viewer can store all resources of entire document.
+Othervise pdfwrite assumes that the viewer can store resources of a single page.
+
+In the second case pdfwrite cleans internal resource caches after each page,
+so that any new resource usage will generate another resource instance
+in the output PDF file.
+
+To inform the viewer that the resources may be cleaned,
+we add a new key to a page contents stream dictionary.
+This is our extension to the PDF specification in order to control
+the resource management in the viewer.
+The new key name is /.CleanResources.
+Currently we provide only the value /All. It means that resources
+may be cleaned *after* ending the contents stream.
+
+In future on necessity we can split a page contents stream into substreams
+and provide a finer control by resource types with providing
+more values for the key /.CleanResources.
+
+When the viewer is informed with allowing to clean resources,
+it is not obliged to do so. Further resource appearences simply replace
+old ones, if they have same resource name.
+Actually now this happens only with font and CID font resources.
+Other resource instances may persist in the viewer's memory until
+the viewer's garbager frees them when they are not
+referred from resource tree dictionaries.
+
+The resource control is mainly intended for ps2write.
+An implementation of the viewer's side (in opdfread.ps) will be a separate patch.
+
+Note that when a resource control is being applied,
+the output document size may increase significantly.
+
+Currently we don't add MaxViewerMemorySize to user's documentation,
+because it depends on another undocumenmted parameter ForOPDFRead
+through the ResourcesBeforeUsage flag. First we need to take a decision
+whether ps2write will become a new Ghostscript device or it stays a tool
+represented with a script. The latter gives more flexibility to users
+about composing the header procsets of the generated Postscript document.
+
+EXPECTED DIFFERENCES :

+ps2write : Convert shadings into a clipped image (continued 4).
+
+DETAILS :
+
+Implement a downsampling when converting a shading into bitmap.
+
+1. A new device parameter MaxShadingBitmapSize controls the downsampling.
+   Shadings, which give a (uncompressed) bitmap over the specified size,
+   will be scaled down.
+
+2. The scaling algorithm goes to gdevpdfd.c .
+   It appears pretty tricky because we need to setup a device with a smaller
+   resolution than the target device. Due to that we need to scale paths and colors,
+   which are represented in the device space. The function scale_path works for it.
+
+3. The scaling creates a local copy of a device color (which handles the shading)
+   and scales the color. Since we can't access further spatial transformations of the color,
+   we apply some unusual operation : multiply matrices in the reverse order
+   than usual 'concat' does. This makes some useful equations to be soluble
+   due to the offset is being scaled as well.
+
+4. A code portion was copied from gx_default_fill_path
+   (see comment in code).
+   We're unhappy about uncomfortable code structurization.
+
+5. path_scale is implemented with floating point for a debug purpose,
+   but in production we use only integers being a power of 2.
+
+6. There is a problem with
+   <</PatternImagemask false /MaxClipPathSize 12000 /MaxShadingBitmapSize 100000000>>
+   The problem happens when dividing the scaled bitmap in smaller ones
+   due to clip path overflow. This mode to be debugged separately.
+   For now set either smaller bitmap size of bigger clip path size.
+   Default settings work fine for most cases.

+are much larger than the page.)  We determine which part of the pattern
+will actually be used and limit the pattern accumulation to the area
+which is needed.  Most of this fix consists of stepping the pattern to
+check the intersection between the pattern and the page.  The major
+complication in this process is simply due to the arbitrary transform
+matrix which can be applied between the coordinate space used to define
+the pattern and the coordinate frame of the output page.
+
+This fix significantly reduces the buffer sizes required for these
+test files.  However it is still possible for a pattern buffer to
+exceed available memory.  It is possible to create a solution using some
+version of a band list.  However my estimate on that task keeps getting
+larger as I look at the details.</pre>

+(the other 2 ones replace "[0]" with "[1]" and "[2]").

+((((1 << 2) * 8 - 9 - 2) < (10)) ? ((1 << 2) * 8 - 9 - 2) : (10))
+is always within the interval [0, 10] and therefore it claims a possible error.
+This patch replaces it with a dynamic constant 's',
+so that the warning doesn't appear.
+In any case we believe that the huge expression above isn't a
+good coding style since humans need to read the code sometimes.
+

+YYY = ((int)(tabc[0]) & ((1 << XXX) - 1))
+ZZZ = ((tabc[0]) >> XXX)
+TTT = (pcrd->caches.EncodeABC[0].fixeds.ints.values)
+
+Using them the expression reduces to :

+(8 >= XXX) ? ((TTT[ZZZ] + (frac)(((long)(TTT[ZZZ + 1] - TTT[ZZZ]) * YYY) >> (XXX))) << (8 - XXX))
+           : ((TTT[ZZZ] + (frac)(((long)(TTT[ZZZ + 1] - TTT[ZZZ]) * YYY) >> (XXX))) >> -(8 - XXX))

+<pre>
+Fix for 687696 PDF 1.4 transparency can use large chunks of memory.
+Prior to this fix the handling of PDF 1.4 transparency features used one
+or more full size image buffers.  With high resolutions and large images,
+these buffers can be multiple gigabytes.  As a result, we were not able
+to handle these files.
+
+DETAILS:
+
+PDF 1.4 transparency is handled by a device which is inserted into the
+device chain.  Prior to this fix, this device was via the 'device filter'
+logic.  With this fix, the PDF 1.4 transparency device is inserted via
+the compositor device mechanism.  This change was made since the device
+filter logic did not allow other devices to control where the PDF 1.4
+transparency device is placed in the device chain.  There is a device
+proc which implements the create compositor action.  This allows more
+control than the device filter logic.
+
+The first step in this fix was to convert the PDF 1.4 transparency
+logic to use the create compositor mechanism.  For situations in which
+the clist logic is not being used, the PDF 1.4 transparency device is
+created and placed in the same location in the device chain as it was put
+by the device filter logic.  In this situation, there is very little
+logical difference in the operation of the PDF 1.4 transparency.
+
+For situations in which the clist is used, there are two PDF 1.4
+compositing devices created.  There is one device before the clist when the
+clist is being written.  There is a second device after the clist when
+the clist data is being read.
+
+The device before the clist serves two purposes, it provides a means for
+implementing the process color model for the PDF 1.4 compositing.  (The
+PDF 1.4 compositing may used a different process color model from the output
+device.)  Thus this device has color_info and encode/decode color procs
+which match the PDF 1.4 blending color space.  This device also ensures
+that the PDF 1.4 blending parameters (blend mode, shape, opacity, etc.)
+are passed through the clist to the second PDF 1.4 device.
+
+The second PDF 1.4 device (the one when the clist is being read) is the
+same PDF 1.4 compositing device which is used when the clist is not being
+used.  This is the device which does the blending operations.  Since the
+device is after the clist, the buffers that it needs are the size of a
+single band instead of the full page.  This device is placed prior to
+the memory device which is used for drawing the raster data.
+
+Two changes were made in the 'create compositor' logic.  The imager state
+was being passed as a 'const'.  It is no longer const since the PDF 1.4
+transparency compositing changes the cmap procs in the imager state to not
+use transfer functions during color calculations.  The transfer functions
+are applied later (and the cmap procs restored) when blended image data
+is output from the PDF 1.4 compositing buffers.
+
+The second change to the create compositor logic is the addition of two
+more procedures to the gs_composite_type_t.procs list.  These procedures
+are used by the clist device create compositor routines.  The first
+is used to create the PDF 1.4 clist write device.  The second saves and
+restores the color_info field for the clist device (see below).
+
+Default versions of the added gs_composite_t.procs were also added for
+use by the other compositor devices.  The defaults are no-ops.
+
+The clist logic has a few changes.  Since the PDF 1.4 compositor device
+may use a different process color model from the output device, the number
+of colorants and the depth (bits per pixel) can be different for the PDF
+1.4 compositor and the output device.  Thus changes were needed in parts
+of the clist logic which assumed that these items were constant during the
+processing of the clist.  An extra field was added to the device halftone
+to indicate the number of colorants in effect when the device halftone was
+created.  This data is included when the halftone is serialized for the
+clist.  (Fortunately the PDF 1.4 compositing does not use halftones or
+transfer functions.  So the device halftones and transfer functions do
+not need to be changed when the PDF 1.4 compositor is installed.)
+
+As previously mentioned the create compositor procedures for the clist
+writer and reader now call a couple of compositor specific routines.  These
+allow the compositor to implement actions related to the clist device.
+(The PDF 1.4 compositor uses these routines to create the 'write clist'
+PDF 1.4 compositor and to save and restore the clist device color info.
+The color_info field of the clist device is changed to match the process
+color model of the PDF 1.4 compositor while the PDF 1.4 compositor is active.
+
+A additional device parameter (PageUsesTransparency) was added.  This
+parameter is sent by the PDF interpreter to indicate if PDF 1.4 transparency
+will be used on the page.  The banding/no banding decision and the size
+of a band includes an estimate of the size of the PDF 1.4 blending buffers
+if this parameter is true.  Note:  The estimate of the size of the
+blending buffers is not exact since this calculation is made before the
+actual number of buffers, the number of blending colors and alpha channels
+is known.  Fixed values are used for the estimated buffer size.  This is
+still much better than the pervious situation, in which the only the
+output raster size was being used.  The blending buffers can easily be
+30 or more times larger than the raster buffer.
+
+This fix also involves the removal of the PDF 1.4 'marking' devices.
+The marking devices were used to actually implement the pixel marking.
+The marking devices were created at the start of each high level drawing
+operation and deleted after the completion of the operation.  The marking
+device action has been merged into the primary PDF 1.4 compositing device.
+This change eliminates some device creation overhead.  The overhead would
+have been worse since most information about high level drawing operations
+is not passed through the clist.  As a result it would have been necessary
+to create marking devices for each low level operations.
+
+The following issues are not included in this fix but need to be considered.
+
+1)  The device filter logic is no longer used.  It may be desired to remove
+this logic.
+
+2)  We currently have a 'create_compositor' device proc.  However there
+is not a 'delete_compositor' device proc.  As a result, compositor devices
+can stay in the device chain even when they are no longer needed.  The
+current fix turns the PDF 1.4 compositor into a 'forwarding' device.  This
+is the same method used by the overprint compositor device.  I do not like
+leaving these devices since there is some extra overhead and there may be
+possible side effects.  (Testing has been done to try to find side effects
+and none has been found with the current code.)
+
+3)  This change only affects devices which can use the clist logic.  This
+excludes the 'high' level devices.  These include the 'display', 'x11',
+and 'pdfwrite' devices.  Thus these device will continue to use a full

+Compile Ghostscript for 64-bit Windows with AMD64 processor.
+Change the default install directory to "c:\program files\gs".
+
+DETAILS:
+Microsoft Visual Studio .NET 2003 with Windows Server 2003 DDK,
+or Microsoft Visual Studio 8 (.NET 2005 beta) are required
+to compile for 64-bits.
+
+Dialog boxes return type INT_PTR not BOOL.
+
+Install to the "Program Files" directory as default,
+instead of c:\gs.  This allows 32-bit and 64-bit
+versions to be installed in separate locations.
+For 32-bit GS on 32-bit Windows, "c:\Program Files\gs"
+For 32-bit GS on 64-bit Windows, "c:\Program Files (x86)\gs"
+For 64-bit GS on 64-bit Windows, "c:\Program Files\gs"
+The " (x86)" is added by Windows when a 32-bit program asks
+for the "Program Files" folder on 64-bit Windows.
+Other languages will translate "Program Files".
+
+The programs still have "32" in their names: gswin32c.exe,
+gswin32.exe and gsdll32.dll.  They are distinguished from
+the 32-bit versions by their install location.
+This avoids changes to many batch files.
+
+The registry entries written by the installer do not
+conflict between 32 and 64-bit.
+For 32 on 32, or 64 on 64, the location is
+  HKLM\Software\AFPL Ghostscript\N.NN
+For 32 on 64, Windows adds "WoW6432Node\" to make it
+  HKLM\Software\Wow6432Node\AFPL Ghostscript\N.NN
+
+If the "Program Files" folder has a " (x86)" suffix,
+this is used as a suffix on the Start Menu items.  This
+allows 32-bit and 64-bit GS to be installed without
+conflict.  The start menu item for 32-bit GS on 64-bit
+Windows is "Ghostscript N.NN (x86)".
+
+Building 64-bit GS on 32-bit Windows can be done
+by the usual method - either execute genconf.exe on
+a 64-bit platform or hand edit arch.h.
+
+A separate patch will fix the display device DisplayHandle
+parameter which is currently truncated to 32-bits.
+
+There is a warning from the linker about exports being
+defined multiple ways.  This is not a problem with the
+32-bit compile.  This is due to the C code
+specifying export and the module definition file
+also specifying the export.  Removing the function
+names from the module definition file would make the
+warning message go away, but may affect 32-bit compiles.</pre>

+Change display device parameter DisplayHandle from an integer
+to a string, to add support for 64-bit platforms.
+
+DETAILS:
+The display device passes a (void *) handle to callback functions.
+The handle is set before the device is opened, and attempting to
+change it afterwards is an error.
+The handle may be used by the caller to identify an instance of
+the display device, for example it may point to the display instance
+object in the caller.
+This handle was set using a PostScript integer which is 32-bits long,
+typically with -dDisplayHandle.
+The existing code will not work correctly on 64-bit architectures.
+
+The display device is changed to return a string as the
+DisplayHandle parameter.
+Previously the handle would be set using -dDisplayHandle=1234.
+The changed code allows it to be passed as
+ -dDisplayHandle=1234
+ -sDisplayHandle=1234
+ -sDisplayHandle=10#1234
+ -sDisplayHandle=16#04d2
+This should be backward compatible, since users of the
+display device will most likely only set the DisplayHandle,
+not read its value.
+
+The ghostscript example code in dw*.c, dx*.c and dp*.c
+does not use DisplayHandle, so is unaffected by this change.
+GSview does use DisplayHandle and will require this
+change for operation on 64-bit platforms.
+
+It is assumed that size_t is an integer with the same size
+as a pointer.

+Eliminate a performance problem when a TT font has a large 'loca' table.
+A fix for 687889 used .sort on the 'loca' table but this takes a long
+time if the table is large. Only run the .sort if the table is out of
+order which is rare since the TT font spec requires an in-order table.
+Bug 687968.
+
+DETAILS:
+
+Apparently our conversion of the 'japan.ps' file creates a TT font with
+a loca table that has 20458 entries (even though the original font
+in japan.ps didn't have that many). This is needed because there are
+many glyphs that are not present, but we need loca table slots that
+represent the missing glyphs (same starting offset as next glyph).
+
+The time was being spent doing the '{ lt } .sort' of the array  :-(
+
+I added logic that checked the order as the loca table was converted
+to an array so that the .sort could be skipped as long as the table is
+in order (which it *should* be for a valid TT font). After this change,
+the HEAD time is 1.16 CPU seconds versus 1.08 seconds for gs8.50.
+(with the .sort, the time was 257 seconds).
+
+I suppose that we could optimize the .sort (put it into 'C') but
+for now I'll just avoid it most of the time.
+
+Note that since the .sort has a procedure callout for the ordering test,
+it might not speed up that much in 'C'. That's the other reason that it
+is worthwhile to avoid the .sort when possible.</pre>

+pdfwrite : Use character codes instead CIDs when creating a ToUnicode CMap.
+
+DETAILS :
+
+Bug 687954 "copy and pasting asian text problems".
+
+The problem depends on what a Postscript printer driver
+puts into the GlyphNames2Unicode table.
+
+GlyphNames2Unicode is an undocumented feature, which PScript5.dll uses to
+communicate with Adobe Distiller. A long ago from its name
+we concluded that it maps character names to Unicode, and it was
+confirmed with multiple documents. Now we got a document
+(the test case of the bug 687954), which uses character codes instead CIDs,
+(CIDs are usually interpreted as "glyph names" in the case of CID fonts).
+In the test document CIDs are not equal to character codes due to the embedded CMap
+named WinCharSetFFFF-H2. We did not notice this problem before
+due to most old documents from PScript5.dll use an identity CMap WinCharSetFFFF-H,
+
+Now we change Ghostscript with using character codes instead CIDs
+as keys to GlyphNames2Unicode. We have no technology for a regression test
+of the related behavior. We will pass this revision to users in order to study
+consequences of this patch from users' responses.

+<pre>
+Fix handling of broken TrueType fonts that have a loca table that is not
+in order. Bug 687889 for customer 670.
+
+DETAILS:
+
+This is clearly a questionable TT font since the Apple TT font reference
+manual clearly states that the length of glyphs can be inferred from
+the difference in successive offsets.
+
+Note that the PostScript code only needs to deal with the sorted 'locatable'
+in order to decide where to split the glyf strings in the sfnts array
+(in the .dividesfnts proc). Otherwise the PostScript code doesn't care.
+
+If the .dividesfnts uses a sorted locatable, but doesn't replace the 'loca'
+table written into the sfnts, then the VMerror occurs because the C code
+in 'default_get_outline' calculated the glyph_length for the gs_alloc
+using loca table entries that might be out of order.
+
+In order to effect the entire fix, I sorted the 'locatable' for the PS
+code in .dividesfnts as well as creating a new 'len_glyphs' array in
+the gs_type42_data structure that holds the actual glyph lengths.
+The glyph lengths are calculated once when the font is initialized in
+gs_type42_font_init. If the 'loca' table is in order, then nothing
+changes, but if it is out of order, we get the lengths by finding the
+next higher glyph offset anywhere in the loca table.
+
+These changes let the file run and show the same glyphs as Adobe Acrobat
+Reader.</pre>

+Implement this dependence implicitly with defining a new function
+psdf_is_converting_image_to_RGB, in order to cancel the "postpone" constraint.
+
+2. Call pdf_color_space before setting up image filters.
+This allows a proper check of the color space compatibility

+ps2write : Unwind the last patch (disallow ICCBased color spaces when writing a ps2write output).
+
+DETAILS :
+
+When applied the last patch,
+we decided to convert ICC profile into a CIEBased color space.
+But ICC profiles (especially ones coming from PDF documents from wild)
+may contain a general lookup table, and a general lookup
+table can't convert into M1*T*M2 transformation,
+where Mi are 3D linear transformations, and and

+
+Besides that, the ICC-based method can't apply to DeviceN spaces.

+Therefore now we choose another implementation strategy.

+ps2write : Allow ICCBased color spaces when writing a ps2write output.
+
+DETAILS :
+
+Since CIEBased is not a PDF 1.2 object, we need to convert it somehow.
+
+One possible way is to write CIEBased into PDF.
+We do not choose this way because (1) it will generate an invalid PDF
+so that we'll not be able to verify the output with PDF readers;
+(2) we have no code for writing a CIEBased color space to PDF or Postscript,
+but we do have one for ICCBased.
+
+Another way is to write ICCBased into the ps2write output
+and to implement a parsing of ICC profile in opdfread.ps .
+We prefer this way since a part of this algorithm (an ICC writer)
+already presents in Ghostscript.
+
+Strongly saying, a PDF with ICCBased is not a valid PDF 1.2 document.
+But as we noticed before, Adobe PDF viewers simply ignore
+pdf level from the document header. So we'll be able to view it
+as it is or after a small modification of the header.
+
+We continue to use the flag OrderResources as a general switch for
+ps2write mode. Doing so because we still have no
+a perfect decision about the list and logics of configuration options.
+Later we'll need to bring more order to this field.
+Possibly writing a "restricted PDF1.3" would be better that
+writing an "extended PDF 1.2".
+
+By the way, pdfwrite appears to have a rudimentary branch
+pdf_convert_cie_to_lab, which currently is a stub,
+which always fails. We think that this conversion isn't possible
+in general due to Lab restricts with a very special class of
+transformations. So lakely this branch will never be implemented
+and it must always fail.
+
+Please note that with this patch ps2write successfully converts
+a smaller class of input files then before it,
+because the writer becomes inconsistent with
+the reader coded in opdfread.ps . But we do need this step
+in the develoipment technology. Actually the files outside the class
+were converted into a too long PDF.

+Fix (pdfwrite) : Improving the heap consistensy with compression chooser.
+
+DETAILS :
+
+When a compression chooser is being installed,
+s_add_fimter may insert another NullEncode filter to comply the buffering
+between the compression chooser and its target.
+After the compression chooser is closed, the old code
+left the NullEncode filter unreleased in the heap,
+so that the heap consistency check claimed a reference
+from it to a freed object, which is the target of the
+NullEncode. It's not a real bug sisnce NullEncode was never referred,
+But running with -Z? got a failure in the heap consistency check.
+
+This patch generalizes the code with closing all filters in the chain
+(including the NullEncode) without a dependence on
+features of specific filters.
+
+BTW, we're unappy of all this stuff,
+becauase actually the compression chooser filter doesn't need any target.
+A dummy one was inserted only to work around a crash in
+s_add_filter, in the check of the buffer size compliance,
+and now we fix a problem with the dummy thing.
+Maybe a simpler way would be patching s_add_filter
+to allow NULL target (I mean no target at all,
+rather than a null filter as the target),
+but we don't want to modify that fundamental thing,
+which is handled by another engineer.

+2. pdfwrite converts self-overlapping patches into an imagemask with a colored pattern color,
+which paints the shading image. See the new code and comments in gdevpdfd.c.
+
+3. An auxiliary function is added to gsptype2.c .
+
+4. Probably we'll need to break big patterns into small ones
+against the printer RAM overflow. Delaying for a while.

+<pre>
+Implementing a conversion of a shading to a raster image for high level devices (continued).
+
+DETAILS :
+
+1. In pdf_copy_color_data, allowed the new value 2 for the parameter for_pattern.
+In this case non-lossless filters are allowed.
+
+2. In gdev_pdf_fill_path, fixed the grouping of clip paths for all
+meshes|patches of a shading.
+
+3. In gdev_pdf_fill_path, used the shading BBox to minimize
+the size of the raster image.
+
+4. In gdevpdfp.c allowed CompatibilityLevel=1.1 .
+Now this is done mainly for debug purpose,
+but likely we'll use it in ps2write when the target doesn't handle TT fonts.
+
+5. The new function gx_dc_pattern2_get_bbox works for (3).
+
+6. The function shade_bbox_transform2fixed has been renamed into
+gx_dc_pattern2_shade_bbox_transform2fixed with making its scope bigger
+to work for (5). It has been moved into gsptype2.c,
+which is mode fundamental than gxshade.c .
+The following changes happened due to that : gsptype2.c, gsptype2.h,
+gsshade.c, gxshade.c, gxshade1.c, gxshade4.c.
+We would like to do more cleanup with replacing it with
+gx_dc_pattern2_get_bbox, but currently we delay that to simplify this patch.
+
+7. Introduced a new field patch_curve_t::straight to know whether a patch
+boundary is a straight line. patch_fill uses it when passing the
+shading coverage area.
+
+8. mesh_triangle now passes the coverage area.
+An auxiliary function mesh_triangle_rec is factored out for that.
+
+9. patch_fill checks for self-overlapoped patches
+and prints a warning is the patch appears suspicious.
+Comments in patch_fill about that have been improved.
+
+10. patch_fill and mesh_triangle check the sign odf the coverage area,
+and change the contour direction for making all contours be positive.
+This works for proper clipping.
+
+11. Fixed compressed streams in opdfread.ps .

+Implementing a convertion of a shading to a raster image for high level devices.
+
+DETAILS :
+
+If a high level device can't handle a shading,
+it is being converted to a raster image.
+
+This patch implements it only in OrderResources mode.
+A generalization to "normal" mode will be done in a separate patch.
+
+The generated bitmap sometimes appears too big since it
+doesn't accout a bbox of a real shading coverage.
+An optimization is coming soon.
+
+1.The device virtual function pattern_manage now handles
+a new request pattern_manage__shading_area.
+If it returns 1, the graphics library will pass
+the shading area as a special call to fill_path,
+with passing NULL images\r state and NULL clipping path.
+Such call immediately follows pattern_manage(...., pattern_manage__shading_area).
+Currently it goes only to a special converter device (see below),
+other devices and the default implementation return 0
+for pattern_manage(...., pattern_manage__shading_area).
+
+2. A new local type pdf_lcvd_t implements a subclass for
+memory device, which is used especially for converting shadings
+to raster image. It is defined locally in pdfwrite.
+The subcalss redefines 4 device methods :
+
+2.1. fill_rectangle with shifting the device space.
+It is used to mapo the shading and its paths to the image coordinate system.
+
+2.2. get_clipping_box returns the target clipping box,
+to deceive a cut-off condition in the shading algorythm.
+
+2.3. pattern_manage returns 1 for pattern_manage__shading_area.
+
+2.4. fill_path is used only for handling the shading area.
+It sets a clipping when instantiating the bitmap.
+
+3. gdev_pdf_fill_path implements the convertion with (2).
+
+4. gs_shading_fill_path doesn't set up a clipper device
+when it works with the shading convertion device.
+Instead that the clipping path is being passed through (2.4).
+
+5,. patch_fill in gxshade6.c checks if the devices needs the
+shading area, and if so, passes the area throuhg the special call to
+fill_path.

+Bug 687847 text missing from CIDFont
+
+From PLRM3 section 5.11 page 389 :
+
+Under special conditions, a CID can be used when the descendant is a Type 3
+base font. The font's BuildGlyph or BuildChar procedure is invoked to render a
+character whose code is the last byte originally extracted from the show string.
+If this procedure executes setfont to establish a CIDFont as the current font
+and then executes a show operation on a string consisting of just that character
+code, the code is ignored; instead, the CID determined by the earlier CMap
+mapping is used to look up the glyph in the CIDFont. This special case exists
+for compatibility with applications that substitute Type 3 fonts for base fonts
+in a composite font hierarchy to achieve certain special effects.

+Fix : A hang adding over 256 glyphs for a stable font copy.
+
+DETAILS :
+
+Bug 687816 "Hang in named_glyph_slot_hashed".
+
+1. Added gs_copied_font_data_s::num_glyphs to monitor
+the current number of glyphs in a stable font copy (gxfcopy.c).
+
+2. copy_glyph_data maintains gs_copied_font_data_s::num_glyphs (gxfcopy.c).
+
+3. gs_copied_can_copy_glyphs checks whether the preallocated
+size of the glyphs array doesn't exceed (gxfcopy.c).
+
+4. copy_glyph_data is fixed to return error code when
+trying to add a glyph over the preallocated size of the glyphs array (gxfcopy.c).
+
+5. pdf_obtain_font_resource_encoded is changed to handle the case when
+new glyphs overflow the font copy (gdevpdtt.c).
+
+The changes above fix the bug, but we also provide an additional optimization
+with GLYPHS_SIZE_IS_PRIME 1 (gxfcopy.c):
+
+6. Preallocate at least 257 ghyphs rather than 256 ones by the old code;
+This coners a font of 256 glyphs and 1 .notdef  (gxfcopy.c).
+(Well, that could fix the hang in the sample case of the bug 687816,
+but generally there exist other cases due to the font merging,
+which require the changes 1-5 above.
+
+7. Use primes numbers for the size of glyphs array instead powers of 2
+against unprodactive expense of RAM (gxfcopy.c).
+
+When the changes 5 was done, a regression happened with tpc2.ps :
+pdfwrite generated an incorrect PDF. To fix that, we forced to do more changes :
+
+8. pdf_register_charproc_font recieved a gs_id of the PS font instead
+the PDF object id. It caused a problem with multiple muster fonts,
+because MM instances have same id as the MM font.
+pdf_encode_string is changed to pass a correct resource id (gdevpdte.c),
+
+9. Since tpc2.ps generates hundreds of MM font instances, the field
+pdf_font_resource_s::u.s.used_fonts may not have a staticly defined size.
+replaced with a dynamicly allocated array (gdevpdtf.h, gdevpdte.c).
+
+10. Garbager descriptor for pdf_font_resource_s is changed to maintain (9).
+
+11. A new function pdf_find_resource_by_resource_id is defined for
+the correct implementation of pdf_used_charproc_fonts (gdevpdfu.c).
+
+After it another tpc2.ps regression persisted : the character 'y'
+dissapperaed in some words. The following changes are done to fix that :
+
+12. Improved thge hash function in pdf_add_subset_prefix (gdevpdtb.c).
+
+13. Defined FINE_GLYPH_USAGE 1 for a better precision of the font subset,
+in the case when a PS interpreter callout happens fro CDevProc or for a Type 3 BuildChar
+(gdevpdfx.h, gdevpdte.c). Currently it works for non-CID fonts only.
+
+14. Improved the diagnistics for the missed glyph in a Type 1 font (gs_type1.ps).
+
+Actually the last regression reflects another problem in the PDF interpreter,
+which is described in a new bug 687856.
+
+EXPECTED DIFFERENCES :
+
+pdfwrite :
+
+test-setweightvector.ps
+tpc2.ps
+
+The distilled tpc2.ps gets 1 progression and 1 regression.
+The progression is the glyph width. The regression is an ununiform
+stem width while rendering the PDF due to problem in the PDF interpreter.
+We describe that problem in the new bug 687857.</pre>
