* Fix: pdfwrite could output Indexed color spaces with more than 256 entries,L Peter Deutsch2002-02-111-0/+3
| | | | | | | | | | or images with more than 8 bits per component, neither of which PDF supports. This patch causes the latter to revert to the millions-of-tiny-rectangles representation, which is not adequate in the long run, but is at least valid output. Fixes SourceForge #513910, for the moment. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@2165 a1074d23-0009-0410-80fe-cf8c14f379e6

* Fix: pdfwrite didn't write transfer functions in the output for images, andL Peter Deutsch2001-07-121-4/+16
| | | | | | | | | | | allowed lossy compressions on images even in the presence of peculiar transfer functions (such as functions simulating indexed color spaces). This fix writes transfer functions for images, prevents lossy compression if the transfer function is not the identity, and undoes the hack that was implemented earlier to work around this problem. Fixes SourceForge bug #420257. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@1595 a1074d23-0009-0410-80fe-cf8c14f379e6

* Substantially enhances the Cos object machinery. Interface: Adds a few moreL Peter Deutsch2000-03-241-9/+8
| | | | | | | | | | | | | | | | | procedures, including a procedure to create a stream that writes directly into a Cos stream object, procedures for putting more kinds of values into arrays and dictionaries, and a param_list interface. Changes Cos objects to store a reference to the PDF device, and removes the device argument from all Cos procedures other than object creation. Replaces the Boolean is_object member of Cos values by a value_type enum: clients must now use COS_VALUE_IS_OBJECT() to test whether a value is an object reference. To reduce allocator overhead, makes the Cos procedures that take C strings no longer copy the string. Records whether each Cos object has been written into the output, so that in the future (but not in this batch of changes) resource definitions can be copied at the end of each page. Implementation: Moves more of the implementation of Cos objects to the .c file. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@200 a1074d23-0009-0410-80fe-cf8c14f379e6

| | | | | | | | | | | | | | | the LockDistillerParams, xxxDownsampleThreshold, xxxImageDict, and xxxACSImageDict distiller parameters. Implements DCTEncode as an xxxImageFilter option (it used to cause a crash). Makes the AutoFilterxxxImages distiller parameters select JPEG encoding (with ACSDict) if the image has 8 bits per component and is not Indexed, and LZW/Flate otherwise: this still isn't right, but it's closer. Implementation changes: Changes the implementation of distiller parameter dictionaries from stream states to parameter lists; changes the test for masks in psdf_setup_image_filters, and changes the image argument from gs_image_t to gs_pixel_image_t. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@166 a1074d23-0009-0410-80fe-cf8c14f379e6
* Adds the ability to set the ProcessColorModel of the pdfwrite device toL Peter Deutsch2000-03-161-15/+37
| | | | | | | | | | | /DeviceGray, /DeviceRGB, or /DeviceCMYK. This affects the color space used for fill, stroke, text, and imagemask, and for images that (for whatever reason) can't be written in their specified color space. Note that this is a short-term fix: pdfwrite should output colors in the color space in which they were specified. However, a proper fix will require more significant architectural changes. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@79 a1074d23-0009-0410-80fe-cf8c14f379e6

Adds gs_iodev_init() to main() procedure. Also, gs_c_param_list_rewrite() is renamed to gs_c_param_list_write_more(). - pcltop.mak - adds pipe.dev for operating system pipe support. - pctext.c, pglabel.c, pxfont.c, plfont.c - extensive modifications to support the text api (gstext.h) - use gs_text_enum_t instead of gs_show_enum. - removes enumeration allocation, this is now done by the text "begin" functions. - update "next_char" procs and "encode char" procs to take a glyph argument and the character argument is now passed by value (pcl nor xl make use of the glyph argument). - char_path_n_init() replaced with gs_charpath_begin(). - gs_show_n_init() replaced with gs_show_begin(). - gs_show_next() is now handled by gs_process_text(). - gs_release_text() added. - gs_xyshow_n_init() replace with gs_xyshow_begin(). Passing of x and y coordinates modified to support the new interface. Unfortunately, we need to transform the coordinates into the space of the font scaling matrix, that is the current ctm for xl when the the text is processed. This differs from postscript which appears to have the regular user->device matrix in the graphics state during processing. - (plfont.c) - gs_notify_init() is now part of the pfont initialization procedure, related TODO: cut over to gs_font_alloc() and gs_font_base_alloc(). - all gs files - removes uninitialized rcs identifiers. KNOWN PROBLEMS: occassional pxl and pcl crashes in gdev_mem_set_line_ptrs() when running in color due to null base (data) pointer. git-svn-id: http://svn.ghostscript.com/ghostpcl/trunk/ghostpcl@985 06663e23-700e-0410-b217-a244a6096597
