When used from - PostScript, however, this structure is allocated using the - gs_memory_default allocator (presumably because the jpeg library - code is not set up to deal with save/restore). - - The gs_memory_default allocator is not a gs_ref_memory_t allocator, - so it does not create the hidden obj_header_t structures preceding - each allocated region. The garbage collector is dependent on these - headers, hence the pointer enumeration routines in structure - descriptors must not enumerate any pointers to memory allocated - by non-gs_ref_memory_t headers. - - This creates a difficult problem for the pointer enumeration - routine of the stream_DCT_state structure, whose data.compress field - points to a jpeg_compress_data structure. This routine would have - to determine which allocator was used for this structure before - deciding whether or not to "enumerate" the data.compress pointer. - In principle it has enough information to do this (the jpeg_memory - field of the structure), but this seems like a overly complicated - solution. Use of a stable gs_ref_memory_t allocator in place of - the gs_memory_default allocator seems like a simpler solution. - - src/zfdcte.c - Modified zDCTE to place the jpeg_compress_data structure into stable - memory rather than use the gs_memory_default allocator. -(zfdcte.c [1.8]: 2002/09/26 18:45:02 dan; checkin for Jan) - -Adds -dDONTPS command line option to disable processing of DoPS directives -in PDF files.

Most of the code changes are required to turn off overprint mode when - processing images, smooth shading fills (shfill operator), or - when using PatternType 2 (smooth shading) patterns. - - 2. A few other changes were required to correct improper updating of the - overprint compositor information. - - 3. The code has been modified to avoid the crash that was observed for - the file 86554321.pdf on MSWindows XP systems. - - 4. The command list playback code has been modified to handle filling of - thin lines in a manner consistent with the noband case. This allows - files such as mspro.pdf to be rendered consistently in the banded and - noband case. - - Jan - - -Modified Files: - - src/gscolor2.c - 1. Modified gs_setcolorspace to call gs_do_set_overprint rather than - invoking the color space's set_overprint routine directly. This - allows pattern color spaces to be handled (somewhat more) correctly. - 2. Modified gs_setcolor to update overprint information. This is - necessary for pattern color spaces, where the color space to be used - for overprint purposes may be part of the color. - - src/gscspace.c - Modified gx_set_overprint_DeviceCMYK to use the effective_overprint_mode - parameter in the image state (rather than the overprint_mode parameter - itself). This is part of the change necessary to allow overprint mode to - be turned off when a PatternType2 pattern is used as the current color. - - src/gsdevice.c - Modified gs_set_device_no_init to call gs_do_set_overprint rather than - invoking the color space's set_overprint routine directly. - - src/gsdps1.c - Modified rectfill to use the effective_overprint_mode parameter in the - imager state (rather than the overprint_mode parameter). - - src/gsovrc.c - 1. Fixed a bug in overprint_draw_thin_line: the third and fourth - operands in the call to gx_default_draw_thin_line (the y coordinate - of the first point and the x-coordinate of the second) were - in reverse order. This caused random lines to appear on various - overprint mode tests (e.g.: BEST99-00-Path.fh7.pdf, - Testform.v1.0.2.pdf). - 2. Fixed typo in comment. - 3. Modified the fill_in_procs procedure to initialize the device color - model information for the temporary device used in this routine. - Though the color model information does not affect the output of - the routine, reasonable values must be provided to avoid problems - when gx_device_forward_fill_in_procs calls gx_device_fill_in_procs. - This would cause certain systems to crash with files that involved - overprint/overprint mode (e.g.: 86554321.pdf on MSWinXP/MSVC systems). - 4. Modified several checks that treated the separable_and_linear flag - in the device color model information as a boolean to handle this - parameter as an enumeration instead (since it is an enumeration). - - src/gsptype1.c - Added gs_pattern1_set_color, the set_color method appropriate for - PatternType 1 patterns. This method performs overprint updating at - setcolor time, a requirement for patterns as the "colorspace" to be - used for overprint purposes is determined (in part) by the current - "color" (pattern). - - src/gsptype2.c - Added gs_pattern2_set_color, the set_color method appropriate for - PatternType 2 patterns. - - src/gsstate.c - 1. Changed the criterion used in gs_grestore_only to determine if the - overprint compositor must be updated. Restoring the graphic state - may change the current color, which in the case of patterns may - change the "colorspace" to be used for overprint purposes. The code - now properly handles this possibility. - 2. Added the gs_do_set_overprint routine, and modified various other - routines that directly call the current color space's - set_overprint method to call this procedure instead. The procedure - implements the special handling required for pattern color spaces, - where the current color may need to be considered when determining - which color model components must be retained. - 3. Added code to initialize the effective_overprint_mode parameter in - the imager state, and provided two external routines to manipulate - this parameter. The first routine, gs_disable_effective_overprint_mode, - sets the effective_overprint_mode parameter to false, irrespective - of the setting of the overprint_mode parameter. The second, - gs_reset_effective_overprint_mode, sets the effective_overprint_mode - parameter to have the same value as the overprint_mode parameter. - The effective_overprint_mode parameter is used to turn off - overprint_mode when a PatternType 2 pattern is being used. - - src/gsstate.h - Added prototypes for gs_do_set_overprint, - gs_disable_effective_overprint_mode, and - gs_reset_effective_overprint_mode. - - src/gxccache.c - Modified gx_image_cached_char to invoke gx_set_dev_color before calling - (non-standard) device fill_mask methods. This handles several - situations in which a device color is not set when a cached character - is to be imaged, in particular for the command list device. - - src/gxclpath.c - Added a comment to indicate that, though the overprint and - overprint_mode parameters are passed through the command list, they - usually have no effect, as overprint is controlled by the compositor - information that is (also) passed through the command list. - - src/gxclrast.c - 1. Added a comment to indicate that the overprint and overprint mode - parameters passed through the command list usually have no effect. - 2. Added code to initialize the effective_parameter_mode field in the - imager state (though this field is usually in-effective). - 3. Initialized the fill_zero_width field of the fill_params structure - in clist_playback_band to have the same value as in the noband case. - This parameter was previously always set to false, which led to - dropped lines for some files (e.g.: mspro.pdf). - - src/gxistate.h - Added the effective_overprint_mode parameter. - - src/gxpcolor.h - Added a set_color method to the pattern method vector. This method - performs any PatternType-specific actions necessary at setcolor - time. For now, this just updates the overprint compositor as required. -(gscolor2.c [1.11], gscspace.c [1.8], gsdevice.c [1.16], gsdps1.c -[1.7], gsovrc.c [1.2], gsptype1.c [1.10], gsptype2.c [1.10], gsstate.c -[1.17], gsstate.h [1.7], gxccache.c [1.11], gxclpath.c [1.16], -gxclrast.c [1.21], gxistate.h [1.13], gxpcolor.h [1.7]: 2002/09/10 -22:16:07 dan; checkin for Jan) - -The last code change for the this file was incorrect and should be replaced -with this entry.

(gscdef.c [1.26]: 2002/09/12 -09:52:20 giles) - - - src/gxccache.c - 1. Fixed numerous problems with compress_alpha_bits and its invocation in - gx_image_cached_char. The former procedure is called only if anti- - aliasing (text alpha bits > 1) is called for a color that requires - halftoning or for a device, such as pbmraw, that does not support the - copy_alpha method. This happens infrequently, and the code was - apparently never used. - 2. Moved the invocation of gs_set_dev_color to an earlier location in - gx_image_cached_char, so that the device color will be set before - any check is made to see if it is a pure color. - - src/gxclimag.c - 1. Added code in clist_fill_mask to return an error if the mask to be - filled has depth > 1 and clist_disable_copy_alpha flag is set in the - disable_mask field. The latter will be the case if the target device - does not support copy alpha. The command list translates fill_mask - calls into copy_alpha calls, which drives this requirement. By - returning an error, the fall-back mechanism included in - gx_image_cached_char (gxccache.c), which is the only client of the - fill_mask method, can function properly. - 2. Also modified clist_fill_mask to check that the drawing color is - pure if depth > 1 and use the default fill_mask method if this is - not the case. (The copy_alpha call to which the command list code will - translate the fill_mask works only for pure colors.) In addition, if - the color is pure, the clist_fill_mask routine will now send commands - to set color1 as well as transmit the device color; the code in - clist_playback_band (gxclrast.c) assumes that all "copy_mono" and - "copy_alpha" commands have set color1. - - src/gxclist.c - Added code in clist_init_data to set the clist_disable_copy_alpha bit - in the disable_mask field if the target device does not support the - copy_alpha method. This must be done in this rather unintuitive location - because it is impossible to tell if the target device supports copy_alpha - until it has been made into a memory device (via the create_buf_device - buffer device method). - - src/gxclist.h - Defined the clist_disable_copy_alpha bit, which is used in the - disable_mask field to indicate that the target device does not support - the copy_alpha method. - - src/gxclrast.c - Added include of gzht.h, to silence some compiler complaints. - - src/gxclrect.c - Modified clist_copy_alpha to return an error if clist_disable_copy_alpha - bit is set in the disable_mask field. This bit indicates that the target - device does not support the copy_alpha method, so we might as well - return an error now, while there is a chance the client might be able to - do something about it. -(gxccache.c [1.12], gxclimag.c [1.9], gxclist.c [1.9], gxclist.h -[1.6], gxclrast.c [1.22], gxclrect.c [1.5]: 2002/09/13 22:21:22 dan; -checkin for Jan) - -Add a macro to eliminate compiler warnings if size of gx_color_index is only -4 bytes.

Most of the problems with the FTS were accounted for by a relatively - harmless dangling pointer problem for paths. In order to support the - charpath operator, paths are normally constructed in stable memory - (not subject to save/restore). However, clipping paths were - constructed in normal memory. If the clippath operator was used to - make the clipping path the current path, the top-level - gx_path_segments would be in stable memory, while the rest of the - path would be in normal memory. A restore operation could then - leave dangling pointers. - - This is not normally a problem, because the grestore operation - associated with the restore would clear the gx_path_segments - structure. This only works on the graphic state stack, however; - graphic state objects stored in VM would not be reset. - - This is harmful only in a very obscure case when the charpath operator - is used on a user-defined font whose BuildGlyph procedure contains - internal save/restore operators and which builds part of its - output with the clippath operator. As far as we know, this has - never occurred in practice. - - 2. [...zDCTE stable memory...] - - 3. If an overprint compositor was used with a banding device, the code - in clist_playback_band was not cleaning up this compositor before - exiting. This caused difficulty with the p2b-100.pdf file. This - code has been modified to close the target device if this device - does not match the original target device with which the routine - was invoked. - - 4. For historical reasons, the link between a halftone order and its - tile cache is a bit peculiar. The order includes a pointer to the - tile cache, and the tile cache keeps a copy of the order, which - points to the same levels/bit data structure of the original order. - Because of these two-way points, the order and its tile cache must - use the same memory allocator to avoid dangling pointer problems. - The code patch modifies gx_imager_dev_ht_install (gsht.c) to - preserve this invariant. The change fixes another problem noted for - p2b-100.pdf. - -With these changes, we are able to run both the PS3 FTS and the full set -of pdf regression files using the '-Z@$?' switch with no reported problems. - - - Jan - -Modified files: - - src/gspaint.c - src/gspath.c - In gs_strokepath and gs_clippath, cause the newly constructed path to - use the memory allocator of the current path, rather than the memory - of the current graphic state.

System VM is intrinsically stable (its associated stable +allocator is the same allocator)" Bug #530588 (gsmalloc.c [1.11]: 2002/10/31 +16:52:18 alexcher) + +Bump version after the 7.31 release. (gscdef.c [1.28]: 2002/10/28 20:11:08 +giles) + +Remove some interpreter references from the graphics library. Partial fix +for SourceForge bug #542848, "library #includes interpreter headers". +(gsargs.c [1.8]: 2002/10/29 09:22:29 ghostgum) + +Revert previous 1.13 patch since it fails on several Genoa tests including +012-09.ps (gsptype1.c [1.14]: 2002/11/02 00:23:06 ray) + +Adds WTS cases for 0 and 45 degree angles, called "Screen H" in the code. +(gswts.c [1.4], gswts.h [1.2], gxwts.c [1.5], gxwts.h [1.2]: 2002/11/02 +07:31:45 raph) + +Adds UseWTS user parameter to enable WTS, rather than a compile-time #define +USE_WTS as before. Also, WTS is now only enabled when AccurateScreens is +selected.
