Procedures

Fixes problems:
	- Speed up shading type 1. (lib.mak [1.47]: 2001/04/05 08:32:28
igorm)

Adds target to OS/2 makefile to build distribution zip archive. Disables
multiple image windows for OS/2 because we can't tell when subsequent
windows are closed. To allow multiple windows we would need to rewrite
gspmdrv.c. (os2.mak [1.14]: 2001/04/01 10:13:24 ghostgum)

Remove the bmpa*** devices from the default build. These are example devices
to demonstrate async rendering but do not have any advantages to users over
the bmp*** devices, and their inclusion requires thread support which is not
available on all systems. Resolves SourceForge bug #213799.
(unix-gcc.mak [1.15], unixansi.mak [1.11], unixtrad.mak [1.11]: 2001/04/03
20:04:46 rayjj)

updates to support libpng v1.0.9. (all-arch.mak [1.7], bcwin32.mak [1.9],
dvx-gcc.mak [1.9], libpng.mak [1.5], msvc32.mak [1.14], msvclib.mak [1.11],

watclib.mak [1.11], watcw32.mak [1.10]: 2001/04/04 07:51:15 giles)

updates to support libpng v1.0.10. OS/2 makefile fixup for v1.0.9 and above
from Russell Lang. (all-arch.mak [1.8], bcwin32.mak [1.10],

watclib.mak [1.12], watcw32.mak [1.11]: 2001/04/06 07:27:22 giles)

Integrates patch from hpijs 0.94 so that Ghostscript can use hpijs drivers.
(contrib.mak [1.23]: 2001/04/07 00:33:29 raph)

Changes default XLIBDIR and XINCLUDE to /usr/X11R6, which is far more likely
than the previous values. (contrib.mak [1.24], ugcclib.mak [1.12],
unix-gcc.mak [1.18], unixtrad.mak [1.14]: 2001/04/07 06:50:27 raph)

Updates version number and date in preparation for 6.64 release. Updates
Develop.htm to accurately list source files. (version.mak [1.32]: 2001/04/07
07:55:25 raph)


Utilities

Fixes problems:
	- -dDELAYSAFER flag added; append operator fixed in Windows and OS/2
scripts; literal newlines removed from sed script. Bugs #223896, #230699
(lib/ps2epsi [1.5], lib/ps2epsi.bat [1.4], lib/ps2epsi.cmd [1.2],
lib/ps2epsi.ps [1.5]: 2001/04/04 04:45:42 alexcher)
	- The fileposition operator cannot be used on some data sources. Use
.fileposition (if on Ghostscript) and make some other changes to make this
portable to other PostScript interpreters. SourceForge bug #223005.
(lib/image-qa.ps [1.3]: 2001/04/04 04:54:53 rayjj)
	- Previous fix had OutputFile set to a debug value. Restoring it to
NUL (lib/ps2epsi.bat [1.5]: 2001/04/04 05:19:33 alexcher)
	- Adds whitespace to sed command in ps2epsi, needed on RedHat Linux 6.2.
(lib/ps2epsi [1.6]: 2001/04/04 21:05:00 raph)


Drivers

Fixes problems:
	- JPEG data made GC-traceable to prevent early freeing. Bug # 227090
gdevjpeg.c gdevpsdu.c sdeparam.c zfdctd.c zfdcte.c : JPEG control structure
is allocated with a descriptor. sdct.h : defines descriptors for JPEG
structures. sjpegc.c : implements the linked list of JPEG core blocks
sjpegd.c sjpege.c : corrects the initialization order of (de)compress
struct's gsstruct.h : yet another macro for a structure with 1 string and 1
ptr (gdevjpeg.c [1.3], gdevpsdu.c [1.10]: 2001/04/04 19:20:27 alexcher)

Integrates patch from hpijs 0.94 so that Ghostscript can use hpijs drivers.
(gdevhpij.c [1.1], gdevhpij.h [1.1]: 2001/04/07 00:33:29 raph)


PDF writer

Fixes problems:
	- Emits W or W* after path construction operators when outputting
clip paths in the pdfwrite driver, to be correct with respect to the PDF
spec. (gdevpdfd.c [1.14]: 2001/04/07 07:12:52 raph)


PDF Interpreter

Fixes problems:
	- The search area for %%EOF at the end of PDF file is increased to
4K to cover a file generated by Distiller 3.02b for AIX 4.1.1 Customer #580
(lib/pdf_main.ps [1.31]: 2001/04/07 01:34:23 alexcher)
	- A comment is corrected to match the source.
(lib/pdf_main.ps [1.32]: 2001/04/07 01:47:00 alexcher)

PDF 1.4 improvements: Fixes garbage collection of device filter stack.
Forces idempotent path drawing in transparency mode. Corrects handling of
Group at toplevel page. (lib/pdf_draw.ps [1.29], lib/pdf_main.ps [1.30]:
2001/04/06 22:23:44 raph)


Interpreter

Fixes problems:
	- Windows poll function now returns a code to interrupt Ghostscript
if the text window is closing. Don't show message box on exit if user closed
the text window. (dwmain.c [1.4], dwtext.c [1.3]: 2001/04/03 11:12:58
ghostgum)
	- equality operation between a pointer and enum constant (with 0
value) is a syntax error on CodeWarrior. Replacing the enum with NULL. From
Bernd Heller (zdscpars.c [1.10]: 2001/04/04 05:25:32 alexcher)
	- Register /All and /None in the name table on look-up. Otherwise an
attempt to set the separation color space fails with /undefined
(zcssepr.c [1.7]: 2001/04/04 16:09:15 alexcher)
	- JPEG data made GC-traceable to prevent early freeing. Bug # 227090
gdevjpeg.c gdevpsdu.c sdeparam.c zfdctd.c zfdcte.c : JPEG control structure
is allocated with a descriptor. sdct.h : defines descriptors for JPEG
structures. sjpegc.c : implements the linked list of JPEG core blocks
sjpegd.c sjpege.c : corrects the initialization order of (de)compress
struct's gsstruct.h : yet another macro for a structure with 1 string and 1
ptr (zfdctd.c [1.4], zfdcte.c [1.4]: 2001/04/04 19:20:27 alexcher)
	- Set default size of MAX_ESTACK to 5000. This is the minimal fix
recommended by L. Peter Deutsch in the followup to SourceForge bug #224095.
This should be fixed later to handle automatic stack expansion. The
approaches are defined by Peter as #2 and #3. Interim resolution to
SorceForge bug #224095. (interp.c [1.8]: 2001/04/06 06:42:45 rayjj)
	- Apparently Japanese Windows uses WM_USER+1 internally and
conflicts with gswin32c messages starting from WM_USER+1. So gswin32c
messages are moved to WM_USER+101 range. Fix from Akira Kakuto
(dwmainc.c [1.4]: 2001/04/06 08:36:02 ghostgum)
	- Do not put Windows stdin into binary mode if it is the console
because this returns CR and LF each time the Enter key is pressed. This
caused Ghostscript to not pause at following showpage prompts.
(dwmainc.c [1.5]: 2001/04/06 08:43:29 ghostgum)
	- Genoa FTS 035-07.ps got a SEGV error caused by data being
allocated in non-GC memory, but pointer enumumeration giving these pointers
to the GC for tracing. Since these objects didn't have GC type headers bad
things happened. Also change one of the allocations in sjpegc.c to immovable
that was not -- this change was not needed to prevent the crash.
(zfdctd.c [1.5]: 2001/04/07 00:33:22 rayjj)
	- Compressed fonts are now recognized as narrow during font
substitution. Customer #580 (lib/gs_fonts.ps [1.11]: 2001/04/07 01:07:01
alexcher)
	- two small issues with compilation under xlc on IBM AIX RS6000, a
name conflict with structures names (u)int64, and trailing commas in enum
declarations. Patch from Dan Coby. Sourceforge bug #414328.
(dscparse.h [1.4]: 2001/04/07 07:28:33 giles)

Adds target to OS/2 makefile to build distribution zip archive. Disables
multiple image windows for OS/2 because we can't tell when subsequent
windows are closed. To allow multiple windows we would need to rewrite
gspmdrv.c. (dpmain.c [1.3]: 2001/04/01 10:13:24 ghostgum)

updates to support libpng v1.0.10. OS/2 makefile fixup for v1.0.9 and above
from Russell Lang. (imain.c [1.11]: 2001/04/06 07:27:22 giles)

Removed unecessary include of Macintosh QDOffscreen.h header (iapi.h [1.2]:
2001/04/06 22:57:46 bdheller)

Uses better test for avoiding crash on "gs -h". Also updates API document.
Thanks to Russell Lang. (imain.c [1.12]: 2001/04/07 00:08:08 raph)

Updates version number and date in preparation for 6.64 release. Updates
Develop.htm to accurately list source files. (lib/gs_init.ps [1.33]:
2001/04/07 07:55:25 raph)

Removes \r\n line ends inadvertently added. (dscparse.h [1.5]: 2001/04/07
08:07:17 raph)

	- Speed up shading type 1. (gsshade.c [1.4], gxshade1.c [1.9]:
2001/04/05 08:32:28 igorm)
	- Some compilers complain that: "Argument of type "stream *" is
incompatible with parameter of type "FILE *". Thanks to Nelson Beebe for
finding this (on SGI). (gs_stdio.h [1.2]: 2001/04/06 03:19:07 rayjj)
	- Fixes crashes in Type 4 function evaluator when stack is empty.
(gsfunc4.c [1.5]: 2001/04/06 22:22:38 raph)

Procedures

Adds %printer% device to Windows to allow a printer to be specified as
-sOutputFile="%printer%Printer Name". This replaces the use of
"\\spool\Printer Name" for all but Windows 3.1/Win32s. Unlike the old
\\spool\, the new %printer% device does not write a large temporary file.
(winlib.mak [1.9]: 2001/03/26 11:28:20 ghostgum)

Adds Windows %printer% device to MS Visual C++ build. (msvc32.mak [1.13]:
2001/03/26 12:00:07 ghostgum)

Adds icclib subdirectory to tarballs. (toolbin/makeset.tcl [1.7]: 2001/03/28
21:24:00 raph)

Increments version number after 6.62 release. (version.mak [1.30]:
2001/03/28 21:27:15 raph)

Applies PDF 1.4 rendering with all devices. Previously, only pnga device
contained PDF 1.4 rendering capabilities. Now, when the PDF 1.4 imaging
model is detected in the source file, it installs the pdf 1.4 rendering
device as a device filter. (lib.mak [1.46]: 2001/04/01 00:30:41 raph)

Updates dates in preparation for 6.63 beta release. News updated.
(version.mak [1.31]: 2001/04/01 01:10:55 raph)


Utilities

Fixes problems:
	- closefile added for procedure based stdio to prevent disabled
stream from appearing valid. (ziodevsc.c [1.2]: 2001/03/27 09:37:10
ghostgum)
	- Avoid rangecheck error when character code exceeds 255. Support
zero-size bitmap used by some fonts for space character.
(lib/bdftops.ps [1.3]: 2001/03/27 20:53:36 alexcher)
	- BATCH parameter is added to all bdftops* scripts
(lib/bdftops [1.2], lib/bdftops.bat [1.3], lib/bdftops.cmd [1.2]: 2001/03/27
21:15:55 alexcher)
	- Corrects memory allocation of command line arguments in the
programs which load the Ghostscript interpreter DLL / shared object.
(dxmain.c [1.2]: 2001/03/31 10:09:47 ghostgum)

Adds %printer% device to Windows to allow a printer to be specified as
-sOutputFile="%printer%Printer Name". This replaces the use of
"\\spool\Printer Name" for all but Windows 3.1/Win32s. Unlike the old
\\spool\, the new %printer% device does not write a large temporary file.
(gp_msprn.c [1.1]: 2001/03/26 11:28:20 ghostgum)


Drivers

Fixes problems:
	- AutoFilter.* options now select lossless compression for the image
smaller than 64 pixels in any dimension. Bug # 226391 from a free user.
(gdevpsdi.c [1.14]: 2001/03/24 04:17:07 alexcher)
	- In the display device, allow NULL as a valid value for
DisplayHandle. Correct the code which requires the device to be closed
before changing the DisplayHandle and DisplayFormat parameters. SourceForge
bug # 411101. (gdevdsp.c [1.2]: 2001/03/28 08:46:15 ghostgum)
	- mdev->memory member was set to 0 causing gx_device_enum_ptr()
not enumerate mdev. This led to freeing of mdev by GC and memory exceptions
during de-allocation of the display device. (gdevdsp.c [1.3]: 2001/03/28
21:50:56 alexcher)
	- Correct memory allocation problems in the display device. Return
correct pointers from display_enum_ptrs so that the memory device and bitmap
are not moved or prematurely freed. Adds a finalize procedure. Change the
memory device to not forward to the display device. Mark the memory device
as retained so it gets freed at the correct time. (gdevdsp.c [1.4],
gdevdsp2.h [1.2]: 2001/03/29 07:26:57 ghostgum)
	- Prevents the buffered mode of the x11 device from missing updates
from the bitmap buffer to the X display. Fix for Artifex customer #1130
(gdevx.c [1.8]: 2001/03/30 18:22:28 rayjj)

Adds Tumble parameter to mswinpr2 device for specifying the duplex
arrangement. Adds QueryUser to the parameters returned by
win_pr2_get_params, so that it works from the command line.
(gdevwpr2.c [1.8]: 2001/03/26 09:44:08 ghostgum)

Adds %printer% device to Windows to allow a printer to be specified as

model is detected in the source file, it installs the pdf 1.4 rendering
device as a device filter. (gdevp14.h [1.1]: 2001/04/01 00:30:41 raph)

Change: The Ghostscript 'pwrite' function name conflicted with the standard
pwrite function defined in unistd.h on several systems. To avoid confusion
with the standard function change the name to stream_write. Also change
'pputc' to 'stream_putc' and 'pputs' to 'stream_puts'. Fixes SourceForge bug
#410772. Fix by Ray Johnston. (gdevps.c [1.16], gdevpsdu.c [1.9],
gdevpsu.c [1.4]: 2001/04/01 00:35:26 raph)


PDF writer

Fixes problems:
	- coordinate range is reduced to +/- 16383 to satisfy actual AR4
restrictions. When CTM was scaled to reduce the range, line width in stroke
and CTM in fill were wrong. Bug # 409105 from raf_mellen at
users.sourceforge.net (gdevpdfd.c [1.12]: 2001/03/21 04:25:48 alexcher)
	- ARTICLE pdfmark generated invalid bead object if /Page key was
left out. Bug # 227651 from mbentley at users.sourceforge.net
(gdevpdfm.c [1.10]: 2001/03/21 05:10:31 alexcher)
	- initial values of fill and stroke color didn't change when
ProcessColorModel changed. An attempt to set white color in CMYK mode was
ignored because it was considered equal to the default color. Bug #410441
from a free user. (gdevpdf.c [1.30]: 2001/03/22 15:12:48 alexcher)
	- pdf_reset_graphics() didn't set correct default color (black) in
/DeviceCMYK color model. An attempt to set white color was ignored because
it was considered equal to the default color causing white objects rendered
black. Bug #410441 from a free user. (gdevpdfg.c [1.11]: 2001/03/23 22:04:19
alexcher)
	- Maximum depth of an outline tree increased from 8 to 32. Bug
#410595 from a free user. (gdevpdfx.h [1.29]: 2001/03/23 22:18:28 alexcher)

Change: The Ghostscript 'pwrite' function name conflicted with the standard

PDF Interpreter

Fixes problems:
	- OmniForm generates PDF files with endobj missing in some objects.
Adobe Acrobat Reader ignores this. Generally speaking, Ghostscript does not
attempt to accept files that grossly fail to obey the Adobe specification
and are produced by software other than a very few extremely widespread
applications. However work-around for this case is easy and unlikely to
break anything. SourceForge bug #406694. (lib/pdf_base.ps [1.14]: 2001/03/20
05:04:59 alexcher)
	- URI action was not converted to corresponding pdfmark and lost
during PDF to PDF conversion. Bug #409245, patch Leon Bottou with some
changes. (lib/pdf_main.ps [1.28]: 2001/03/24 23:59:23 alexcher)

Implementation of security hooks for PDF reader by Geoffrey Keating is
merged into the main GS code base. (lib/pdf_sec.ps [1.3]: 2001/03/25
02:03:44 alexcher)

Applies PDF 1.4 rendering with all devices. Previously, only pnga device
contained PDF 1.4 rendering capabilities. Now, when the PDF 1.4 imaging

Interpreter

Fixes problems:
	- flush procedure based stdout and stderr on exit. (imain.c [1.8]:
2001/03/27 09:38:39 ghostgum)
	- Fix for CIDFontType 0 : 1. Erroneous glyphs are drawn by cshow
(with -dNOCACHE); 2. Glyphs written in horizontal direction instead vertical
(with anti-aliasing); 3. Erroneous glyphs and awkward metrics (with
anti-aliasing and -dNOCACHE); Patches 1 & 3 from Hideyuki Suzuki
(hideyuki), improved by igorm. SourceForge bug #222683. (zchar1.c [1.7]:
2001/03/27 09:56:39 igorm)
	- Changes to introduce the min_left stream state variable set this
to 1 for procedure streams, which caused 1 character to be retained in the
stream buffer which was not passed to the client. This broke the DLL
interface where procedure callouts were used to get the string from the
callback. Procedure streams have no need for EOD lookahead (to force
closure) so the correct min_left value is 0. SourceForge bug #404331.
(zfproc.c [1.9]: 2001/03/29 04:09:40 rayjj)
	- After recognizing a number the scanner wrongly interpreted it as a
name, if the number ends at the end of input buffer. Change from Raph.
SourceForge bug #224205. (iscannum.c [1.3]: 2001/03/29 13:27:59 igorm)
	- Correct the Windows virtual key code passed from the image window
to the console. (dwimg.c [1.2]: 2001/03/31 10:07:48 ghostgum)
	- Put Windows console stdout and stderr in binary mode. Ignore the
initial callout for stdout and stderr as the procedure stream acquires a
buffer. (dwmainc.c [1.2], imain.c [1.9]: 2001/03/31 10:08:43 ghostgum)
	- Corrects memory allocation of command line arguments in the
programs which load the Ghostscript interpreter DLL / shared object.
(dpmain.c [1.2], dwmain.c [1.2], dwmainc.c [1.3]: 2001/03/31 10:09:47
ghostgum)
	- When gswin32 text window is closed, exit the interpreter on next
access to stdin and then destroy the text window. (dwmain.c [1.3],
dwtext.c [1.2], imain.c [1.10]: 2001/03/31 10:11:55 ghostgum)

Change the search order for the Ghostscript Windows DLL to try the
executable directory before the location specified in the GS_DLL environment
variable. (dwdll.c [1.2]: 2001/03/27 09:35:22 ghostgum)

Update mail address from bug-gs@aladdin.com to bug-gs@ghostscript.com.

Library

Fixes problems:
	- The old code can mis-identify ShadingType 1 function as constant
due to testing it at insufficient set of points. Replacing it with slower
accurate code. SourceForge bug #228714. (gxshade.c [1.6], gxshade.h [1.4],

Implement new Ghostscript interpreter API for DLL or shared object.
Reimplement old DLL interface using new API. See iapi.h and iapi.c for new
API. For unix, build using "make so". Added loader programs for Ghostscript
interpreter library for GNU/Linux (dxmain.c), Windows (dw*.c) and OS/2
(dpmain.c). Add new "display" device for use with the new API. GNU/Linux
dxmain.c uses the "display" device, Gtk+ and GdkRgb for faster drawing than
the "x11" device. (devs.mak [1.43], gsdll2.def [1.2], gsdll32.def [1.2],

Drivers

Fixes problems:
	- to achieve page independence, every page must in the general case
set page parameters. To preserve duplexing the page cannot set page
parameters. New code checks the current page size and sets it only if it is
necessary. Bug #404376 reported by bannis at users.sourceforge.net

PDF writer

Fixes problems:
	- properly include unistd_.h in files that call unlink()
(gdevpdf.c [1.29]: 2001/03/16 22:12:34 giles)

Redirect all user messages from stdout and stderr to outwrite() and

PDF Interpreter

Fixes problems:
	- When the stream is located in an external file (i.e. the stream
dictionary contains an /F entry) GS fails with "typecheck in .knownget"
because of a minor bug in stack handling in pdf_base.ps. Bug #229425, the
fix from Andreas Bolsch <meromorphic at users.sourceforge.net>
(lib/pdf_base.ps [1.13]: 2001/03/04 16:59:19 alexcher)
	- GS can override image interpolation using INTERPOLATE or
NOINTERPOLATE flags. These flags had no effect on PDF because the PDF
interpreter is bound earlier than image operator is redefined. New version
takes image and imagemask values from systemdict at run time.
(lib/pdf_draw.ps [1.27]: 2001/03/11 05:15:26 alexcher)

Interpreter

Fixes problems:
	- Allocate filter in local VM when currentglobal is false. Prevents
a problem with some QuarkXpress ProcSets that turn off vmreclaim and expect
save/restore to free memory which only works on local VM. Fix for problem
reported by Artifex customer #150, file "japan.ps". (zfilter.c [1.5]:
2001/02/28 00:39:26 rayjj)
	- Speed-up JPEG decompression by increasing file buffer to 2K. This
avoids installation of an intermediate buffering filter that resulted in a
byte-by-byte filling of the buffer to the JPEG code. When the buffer was not
full enough a recoverable error would result in a round trip for the next
byte. Fixes SourcForge bug #405342 for Artifex customer #350.
(zfile.c [1.7]: 2001/03/02 03:06:50 alexcher)
	- Removes Category dictionary from dictionary stack during the
execution of the /Font resourceforall procedure, needed for proper access
from the procedure to underlying dictionary. Fixes SourceForge bug #224973.
(lib/gs_cidcm.ps [1.2]: 2001/03/03 15:09:12 igorm)
	- GS didn't accept packed array as data source in image with
multiple data sources. From internal bug report. (zimage2.c [1.4]:
2001/03/12 22:53:22 alexcher)
	- ztype9mapcid now allocates string in global memory space to match
allocation of contents. Thanks to Masatake YAMATO for the patch.
(zfcid0.c [1.6]: 2001/03/13 19:57:06 raph)

This fix corrects a problem with VM usage in the DSC parser. Previously the
dictionary dsc_dict was allocated in global VM but the DSC parser would try
to insert items while in local VM mode. This fix forces the DSC parser into
global VM mode. (lib/gs_dscp.ps [1.4]: 2001/03/12 22:41:22 dancoby)

the procedure often caused various errors such as /stackunderfloe.
(gdevpdfs.c [1.2]: 2001/02/06 21:42:38 alexcher)
	- imagemask used the color of previous object if the object had

PDF Interpreter

Fixes problems:
	- skip all bytes after the end of the stream in the inline image
until EOL or EI is found. Some buggy PDF files require this. Fix: In PDF 1.3

Streams

Minor patches for clean VMS compile. Thanks to Jacob (=Jouk) Jansen.
(stdio_.h [1.3]: 2001/02/02 07:52:26 raph)


Library

Fixes problems:
	- egcc - 2.91.66 generates incorrect code for dda_step_add(dxx4,
dxx4); Using the intermediate variable now to wark around the problem. This
bug corrupted memory block headers and caused random crashes.
(gxifast.c [1.3]: 2001/01/25 21:36:17 alexcher)

Changes gx_image_cached_char so that it now images to the device in the text
enumeration, rather than the current device. This change gives more
flexibility for implementations of begin_text to interpose a device of their
own for actual imaging. (gxccache.c [1.3]: 2001/01/04 19:39:24 raph)

Updates documentation in gxdevcli.h on creating device instances.

Version 6.60 (2000-12-31)




This long-overdue fileset includes major new developer documentation, major
improvements in the PDF writer (for embedded fonts and for DSC comments),
and lots of bug fixes.  Unfortunately, for unknown reasons, the release
"smoke test" loops forever on the file data/ps/screen.ps -- but only when
compiled in 'production' mode, not in 'debug' mode.  We suspect a gcc bug,
but don't have the time to track it down before the end of the millennium.

Incompatible changes



(Interpreter)
	- With WMode = 1, CID-keyed fonts with no Metrics2 now use default
metrics computed from FontBBox rather than the horizontal metrics.
(PDF interpreter)
	- The interpreter now skips to the next EOL after reading the data
following the ID operator.
	- The incorrectly named ViewerOrientation DSC comment is now
corrected to ViewingOrientation.
(Streams)
	- All decoding filters that recognize an EOD in the source data
must now have an init procedure that sets state->min_left = 1.
(Library)
	- The glyph_data, subr_data, and seac_data procedures in a Type 1
font (gs_type1_data_procs), and the glyph_data procedure passed to
psf_{check,get}_outline_glyphs, must now return 1 iff the outline string was
newly allocated and should be freed by the caller, like the get_outline
procedure of Type 42 fonts (gs_type42_data).
	- The ip_state structure is renamed ip_state_t, and has a new
member, free_char_string.
	- The incorrectly named ViewerOrientation DSC comment is now
corrected to ViewingOrientation, and the viewer_orientation members of
the DSC parsing structure are corrected to viewing_orientation.




Documentation

Fixes problems:
	- An isolated ampersand needed to be converted to the HTML form.
(doc/Bug-form.htm [1.12]: 2000/11/04 17:53:57 lpd)
	- cvs2hist was generating invalid anchor names and not escaping
special charaters. also enable '-r' commandline option, and pass '-b' if
it's not specified for default branch logs only. Changes.htm now passes the
validator. Minor url cleanup in Release.htm (doc/Changes.htm [1.19],
doc/Release.htm [1.23]: 2000/11/10 01:52:35 giles)
	- Removes obsolete documentation reference to -DUsePrinterImages and
clarifies the entry for the replacing -DPrinted. Fixes sourceforge bug #
121907. (doc/Use.htm [1.16]: 2000/11/20 20:34:23 giles)
	- Type 1 CharStrings loaded from disk for type 0 CIDFonts were never
freed, except by garbage collection (which doesn't reclaim chunks with only
a small amount of surviving data). In practice, this probably only affects
the PDF writer. (doc/News.htm [1.71]: 2000/11/23 23:34:23 lpd)
	- The pswrite device couldn't write to pipes. The fix involved
expanding the API for opening device OutputFiles so that the individual
driver could specify whether it required, requested, or did not want a
positionable file. Fixes SourceForge bug # 122223. (doc/Use.htm [1.17]:
2000/11/29 02:25:13 lpd)
	- The default ps2pdf "distiller parameters" weren't documented
correctly; the parameter values for the other PDFSETTINGS (screen, printer,
prepress) weren't documented at all; the xxxImageDownsampleThreshold
parameters were incorrectly documented as xxxDownsampleThreshold.
(doc/Ps2pdf.htm [1.22]: 2000/12/19 17:55:55 lpd)
	- The documentation of the -dSAFER command line switch was
inaccurate. (doc/Use.htm [1.18]: 2000/12/23 01:33:06 lpd)
	- documentation for gs_cidcm.ps and gs_dscp.ps was missing.

Procedures

Fixes problems:
	- cvs2hist was generating invalid anchor names and not escaping
special charaters. also enable '-r' commandline option, and pass '-b' if
it's not specified for default branch logs only. Changes.htm now passes the
validator. Minor url cleanup in Release.htm (toolbin/cvs2hist.py [1.4]:
2000/11/10 01:52:35 giles)
	- The OS/2 platform code would no longer compile, because the stdio
files are no longer available. (fix from rjl) (os2.mak [1.9]: 2000/12/05
01:16:26 lpd)
	- Embedded font subsets always used similar sequences of prefixes,
making it likely that combining multiple PDF files would lead to clashes;
the code now generates truly random prefixes, using an external source of
random data. (devs.mak [1.39]: 2000/12/10 00:12:23 lpd)
	- Fixes a couple of dependency lists that had gotten out of sync.
(devs.mak [1.40]: 2000/12/10 00:17:51 lpd)
	- Seek was broken and PDF interpreter failed when
FILE_IMPLEMENTATION=fd The implementation of streams using direct OS calls
is extended to support MSVC && Win32. close_.h is replaced by more
general unistd_.h (lib.mak [1.40]: 2000/12/19 03:35:40 alexcher)
	- In the previous fix unistd__h was misspelt as unistd_h .
(lib.mak [1.41]: 2000/12/19 05:35:53 alexcher)
	- The recent change for localized man pages didn't update 2 of the 3
top-level Unix makefiles. (unixansi.mak [1.7], unixtrad.mak [1.7]:
2000/12/23 16:29:53 lpd)
	- The list of doc files to be installed had gotten out of date
(Develop.htm, Maintain.htm, and Ps-style.htm were missing).
(unixinst.mak [1.16]: 2000/12/23 16:30:36 lpd)
	- unixinst.mak was checked in with the previous fix only partly
done. (unixinst.mak [1.17]: 2000/12/23 16:34:12 lpd)

Collect some stray configuration related externs into iconf.h
(int.mak [1.40]: 2000/11/04 06:12:02 rayjj)

Adds DSC parsing capability to the PostScript interpreter, with an optional
'feature' to use the DSC Orientation comments to compensate for sloppy
PostScript producers that don't emit an appropriate setpagedevice command.
(int.mak [1.41]: 2000/11/05 18:33:53 lpd)

Adds the 'hook' for passing DSC comments to the PDF writer, but doesn't
actually process any of the comments. NOTE: Part of this code was
accidentally included in the recent fix for local/global VM problems in the
PostScript code for using the DSC parser. (devs.mak [1.36]: 2000/11/07
18:54:26 lpd)

Reorganizes some text-writing code in anticipation of adding CIDFont and
CMap support. (devs.mak [1.37]: 2000/11/17 22:11:44 lpd)

Avoids exporting empty LD_RUN_PATH environment variable to the link process.
This was causing binaries to search the current directory for libraries,
which was a security hole. Fixes SourceForge bug 122532. (ugcclib.mak [1.6],
unixlink.mak [1.3]: 2000/11/28 00:14:48 raph)

Updates the date and version checker for compatibility with the newest
documentation standards; also makes it check the makefile values of JVERSION
and PVERSION against the currently installed third-party source code.
(toolbin/pre [1.9]: 2000/12/05 21:14:14 lpd)

Extensively revises and updates the pdfwrite text handling code to support
processing and embedding of all types of fonts (except for Type 3 and
CIDFontType 1, which are defined by PostScript procedures), and all variants
of 'show' (including kshow and glyphshow). In particular, Type 0 fonts with
all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both
standard and non-standard CMaps are supported. (devs.mak [1.38],
int.mak [1.42], lib.mak [1.38]: 2000/12/08 23:35:37 lpd)

removes a spurious import of the cgi module (toolbin/cvs2hist.py [1.5]:
2000/12/11 19:40:23 giles)

Splits off the code for downsampling an oversampled character bitmap into a
separate file. (lib.mak [1.39]: 2000/12/14 00:14:52 lpd)

Adds a '-t' option to enable text output rather than html, replacing the old
behavior, which was to return text unless a version string was passed with
'-v'. The version string is now set to 'CVS' if no explicit version is
passed, and this is used in the named anchors within the html output.
(toolbin/cvs2hist.py [1.6]: 2000/12/23 09:38:10 giles)

Adds support for localized manpages to the make 'install' target. On unix
the makefile will now intall any files with the $MAN1EXT extension it finds
under locale subdirs of the man directory that are listed in the MAN_LCDIRS
variable. The $man1dir is correspondingly removed from unix-gcc.mak. Also
adds separate targets: install-doc install-man install-examples
install-libdata (unix-gcc.mak [1.9], unixinst.mak [1.15]: 2000/12/23
10:10:37 giles)

Improves the set of files checked by hrefcov +lib.
(toolbin/hrefcov.tcl [1.5]: 2000/12/29 02:16:13 lpd)

Adds a script for batch-converting PostScript files to PDF, intended to be
useful for testing. (toolbin/many2pdf.tcl [1.1]: 2000/12/31 22:28:09 lpd)

Updates repository for 6.60 release. (toolbin/pre [1.10],
version.mak [1.24]: 2001/01/01 00:24:06 lpd)


Utilities

Fixes problems:
	- pdfopt.ps used the "unresolved?" procedure from pdf_base.ps, which
has been replaced by the slightly different "resolved?" procedure.
(lib/pdfopt.ps [1.4]: 2000/12/01 04:15:52 lpd)
	- The OS/2 platform code would no longer compile, because the stdio
files are no longer available. (fix from rjl) (gp_os2.c [1.5]: 2000/12/05
01:16:26 lpd)
	- File flush method uses file member in stream. On Windows and OS/2
it is NULL for %stdout or %stderr. So the standard flush method is
installed. (gp_msio.c [1.3], gp_os2.c [1.6]: 2000/12/19 03:44:24 alexcher)
	- /NullEncode filter no longer supports fileposition. Replacing
fileposition with .fileposition (lib/impath.ps [1.3]: 2000/12/28 17:06:07
alexcher)
	- _.at file was not deleted in BAT file; SAFER option added to CMD
file. (lib/eps2eps.bat [1.4], lib/eps2eps.cmd [1.2]: 2000/12/30 18:45:37
alexcher)

Improves documentation of cid2code.ps by adding a complete usage example.
(lib/cid2code.ps [1.3]: 2000/11/30 18:22:11 lpd)

Adds extensive documentation to genconf.c; also brings it into line with
current Ghostscript coding standards. (genconf.c [1.4]: 2000/12/20 04:20:34
lpd)

Safe mode implemented using DELAYSAFER flag. (lib/pdf2dsc [1.3],
lib/pdf2dsc.bat [1.1], lib/pdf2dsc.ps [1.3]: 2000/12/29 05:03:49 alexcher)


Drivers

Fixes problems:
	- In PDF output, color values of 1.0 were usually written as 0.999.
(bug introduced in version 6.22) (gdevpsdu.c [1.8]: 2000/11/12 07:13:26 lpd)
	- The pswrite device couldn't write to pipes. The fix involved
expanding the API for opening device OutputFiles so that the individual
driver could specify whether it required, requested, or did not want a
positionable file. Fixes SourceForge bug # 122223. (gdevps.c [1.13],
gdevpx.c [1.5]: 2000/11/29 02:25:13 lpd)
	- Invalid (uninitialized) StripByteCount was being left in file for
the tiff12nc and tiff24nc devices. Needed to call gdev_tiff_end_strip().
(gdevtfnx.c [1.4]: 2000/12/15 06:09:27 rayjj)
	- Fixes bug introduced in gdevxini.c revision 1.5. Don't overwrite
the pixmap handle provided in the GHOSTVIEW environment variable.
(gdevxini.c [1.10]: 2000/12/15 10:18:47 ghostgum)
	- The pswrite device produced an extra page if the transfer function
didn't map "1 setgray" to device white. (gdevps.c [1.14]: 2000/12/21
03:58:54 lpd)


PDF writer

Fixes problems:
	- kshow caused the PDF writer to revert to bitmapped fonts. Fixes
SourceForge bug # 104118. (gdevpdft.c [1.21]: 2000/11/06 04:17:14 lpd)
	- The PDF writer didn't handle stroked fonts correctly (they were
filled instead of stroked). (gdevpdf.c [1.23], gdevpdfd.c [1.11],
gdevpdft.c [1.22], gdevpdfx.h [1.23]: 2000/11/12 06:52:08 lpd)
	- When mixing filled and stroked fonts, the color wasn't set
correctly. (gdevpdft.c [1.23]: 2000/11/12 07:14:30 lpd)
	- The PDF writer incorrectly assumed that in PDF 1.3, the standard
Latin character set was the PostScript 3 extended set (it's actually the old
PostScript Level 2 set). (gdevpdft.c [1.28]: 2000/11/20 18:13:55 lpd)
	- Embedded CIDFontType 2 fonts had an incorrect BoundingBox.
(gdevpdff.c [1.14]: 2000/12/09 06:53:25 lpd)
	- Embedded font subsets always used similar sequences of prefixes,
making it likely that combining multiple PDF files would lead to clashes;
the code now generates truly random prefixes, using an external source of
random data. (gdevpdf.c [1.26], gdevpdfe.c [1.8], gdevpdff.c [1.15],
gdevpdff.h [1.9], gdevpdfx.h [1.27]: 2000/12/10 00:12:23 lpd)
	- Non-embedded Multiple Master instances weren't identified as such
(font Subtype = /MMType1). (gdevpdfw.c [1.7]: 2000/12/11 08:52:01 lpd)
	- pdfwrite would crash if a bitmap character was larger than 10Kb
(compressed). The fix simply raises the limit to 1 Mb. (gdevpdft.c [1.30]:
2000/12/13 01:33:37 lpd)
	- When processing DSC comments, some constant strings weren't copied
to the heap, possibly causing memory access errors. (gdevpdfp.c [1.16]:
2000/12/16 07:02:35 lpd)
	- If the same standard (base 14) font was loaded more than once
(because of save/restore), the PDF file could contain fonts that had
suffixed names (e.g., Helvetica~2) but with data missing as though they were
standard fonts, upsetting Acrobat Reader. Fixes SourceForge bug # 101905.
THIS FIX IS IN A VERY FRAGILE AREA AND MAY INTRODUCE NEW PROBLEMS.
(gdevpdff.c [1.16]: 2000/12/16 08:00:53 lpd)
	- The previous fix for copying DSC comment keys to the heap was
unnecessarily complex. (gdevpdfp.c [1.17]: 2000/12/16 19:28:51 lpd)
	- Resource usage wasn't tracked separately for Form XObjects (BP/EP
pdfmarks), producing non-compliant files that caused errors from Acrobat.
Fixes SourceForge bug # 102146. (gdevpdf.c [1.28], gdevpdff.c [1.17],
gdevpdff.h [1.10], gdevpdfm.c [1.8], gdevpdfo.c [1.6], gdevpdfo.h [1.6],
gdevpdft.c [1.31], gdevpdfu.c [1.14], gdevpdfw.c [1.8], gdevpdfx.h [1.28]:

	- Strict type correctness is required on VMS system. Contributed by
Jouk Jansen joukj@hrem.stm.tudelft.nl (gdevpdfw.c [1.9]: 2000/12/18 21:58:03
alexcher)

Adds the 'hook' for passing DSC comments to the PDF writer, but doesn't
actually process any of the comments. NOTE: Part of this code was
accidentally included in the recent fix for local/global VM problems in the
PostScript code for using the DSC parser. (gdevpdfp.c [1.13]: 2000/11/07
18:54:26 lpd)

Changes the internal indication of whether to allow font subsetting from a
Boolean to OK, YES, NO. (Unfortunately, I no longer remember why this change
is needed.) (gdevpdfe.c [1.6], gdevpdff.c [1.10], gdevpdff.h [1.5],
gdevpdft.c [1.24]: 2000/11/14 06:57:21 lpd)

When writing PDF output, adds the ability to convert text in Type 0 fonts to
text in the descendant leaf fonts. This completes the handling of text
output except for CID-keyed fonts. (gdevpdft.c [1.25]: 2000/11/14 16:47:09
lpd)

Reorganizes some text-writing code in anticipation of adding CIDFont and
CMap support. (gdevpdff.c [1.11], gdevpdff.h [1.6], gdevpdft.c [1.26]:
2000/11/17 22:11:44 lpd)

Makes glyphshow no longer revert to bitmapped fonts. Also adds a CIDFont
pseudo-resource, in anticipation of adding CID-keyed font support.
(gdevpdff.c [1.12], gdevpdff.h [1.7], gdevpdft.c [1.27], gdevpdfx.h [1.24]:
2000/11/20 08:31:20 lpd)

Extensively revises and updates the pdfwrite text handling code to support
processing and embedding of all types of fonts (except for Type 3 and
CIDFontType 1, which are defined by PostScript procedures), and all variants
of 'show' (including kshow and glyphshow). In particular, Type 0 fonts with
all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both
standard and non-standard CMaps are supported. (gdevpdf.c [1.24],
gdevpdfe.c [1.7], gdevpdff.c [1.13], gdevpdff.h [1.8], gdevpdfs.c [1.1],
gdevpdft.c [1.29], gdevpdfu.c [1.13], gdevpdfw.c [1.6], gdevpdfx.h [1.25]:
2000/12/08 23:35:38 lpd)

If ParseDSCCommentsForDocInfo is set to true, copies information from DSC
comments Creator, CreationDate, For, and Title into the output's Info
dictionary. (gdevpdfp.c [1.14]: 2000/12/09 07:49:22 lpd)

Makes the PDF writer extract orientation and bounding box information from
DSC comments, if present. The orientation is used to set Rotate if
AutoRotatePages is not selected; the bounding box is not yet used for
anything. (gdevpdf.c [1.25], gdevpdfp.c [1.15], gdevpdfx.h [1.26]:
2000/12/09 19:54:54 lpd)

Slightly changes the initialization of the random offset for font subset
prefixes, to work better with low-resolution clocks such as those typical on
PCs. (gdevpdf.c [1.27]: 2000/12/16 19:31:10 lpd)


PDF Interpreter

Fixes problems:
	- Type 0 fonts with a non-standard (embedded) CMap didn't work at
all. (lib/pdf_font.ps [1.15]: 2000/12/02 20:41:52 lpd)
	- The PDF interpreter ignored the CIDToGIDMap entry in (embedded)
CIDFontType 2 fonts, producing incorrect output if the map wasn't /Identity.
(lib/pdf_font.ps [1.16]: 2000/12/07 23:41:10 lpd)
	- GS didn't dereference indirect objects in Widths array.
(lib/pdf_font.ps [1.17]: 2000/12/17 19:06:19 alexcher)
	- Fixes a slight oversight in the true/false/null improvement for
the PDF interpreter. (lib/pdf_base.ps [1.12]: 2000/12/26 04:10:12 lpd)
	- When a non-TrueType font was substituted for a TrueType font, the
Encoding in the font descriptor was ignored. This hack was intended to fix
SF bug # 104702, an invalid PDF file, but it broke another case. Removal of
the hack makes GS render both cases similar to AR 4.
(lib/pdf_font.ps [1.18]: 2000/12/26 04:29:30 alexcher)
	- The PDF interpreter didn't rotate the CropBox for landscape pages,
producing incorrect output if the input of ps2pdf was a landscape PDF file.
(lib/pdf_main.ps [1.26]: 2000/12/31 01:07:18 lpd)

Improves font substitution by taking the "Narrow" property into account.
Fixes SourceForge bug 116460. Fix due to Leon Bottou.
(lib/pdf_font.ps [1.13]: 2000/11/05 17:36:28 raph)

Wraps the showpagecontents call in gsave/grestore, so that the graphics
state for drawing annotations is pristine. Fixes Sourceforge bug 123310.
(lib/pdf_main.ps [1.23]: 2000/11/25 22:00:21 raph)

The published PDF specification says the Encoding name "must be" one of the
3 predefined Encodings, implying that an error should occur if it isn't.
However, Acrobat Reader simply ignores unknown names, and since there are
some buggy applications that rely on this, we do the same.
(lib/pdf_font.ps [1.14]: 2000/11/28 18:55:24 alexcher)

The PDF specification says that the 'xref' must be on a line by itself. The
code formerly used readline and linene to check this. However, Acrobat
Reader only requires the line to begin with 'xref', and there are enough
applications producing non-compliant PDF files that we have to do this too.
(lib/pdf_main.ps [1.24]: 2000/12/18 03:41:35 alexcher)

AI8 writes bogus encoding array [0 1 0 0 0 0 0 0] AR doesn't care. So we
have to straighten it up here. (lib/pdf_draw.ps [1.24]: 2000/12/20 19:02:24
alexcher)

Makes the PDF interpreter handle true, false, and null specially, rather
than by dictionary lookup, so that the PostScript interpreter can still
process these names using the special fast case for names defined only in
systemdict. (lib/pdf_base.ps [1.11], lib/pdf_main.ps [1.25]: 2000/12/26
04:08:44 lpd)


Interpreter

Fixes problems:
	- The recently updated code for activating the DSC comment parser
had several local/global VM problems, causing invalidaccess errors.
(lib/gs_dps2.ps [1.3], lib/gs_init.ps [1.27], lib/gs_pdfwr.ps [1.7]:
2000/11/07 18:51:24 lpd)
	- There was still a bug in the code for passing DSC comments to the
PDF writer, causing typecheck errors. (lib/gs_pdfwr.ps [1.8]: 2000/11/07
19:27:14 lpd)
	- If the procedure of a FunctionType 4 Function was syntactically
valid but exceeded the maximum stack depth, an attempt was made to free a
string as an object, causing memory corruption. (zfunc4.c [1.6]: 2000/11/11
17:34:06 lpd)
	- Disk-based TrueType fonts caused a memory leak. (Currently, there
are no such fonts, but CIDFontType 2 fonts, and directly-accessed TrueType
fonts, should be made disk-based.) (zfcid1.c [1.4]: 2000/11/22 08:32:07 lpd)
	- Type 1 CharStrings loaded from disk for type 0 CIDFonts were never
freed, except by garbage collection (which doesn't reclaim chunks with only
a small amount of surviving data). In practice, this probably only affects
the PDF writer. (zfcid0.c [1.5]: 2000/11/23 23:34:22 lpd)
	- Single-byte notdef ranges in CMaps incorrectly incremented the CID
number, rather than assigning the same CID to all characters in the range.
(lib/gs_cmap.ps [1.9]: 2000/11/29 06:58:36 lpd)
	- In dictionaries, an int lookup key sometimes didn't match a real
stored key, and vice versa. Fixes SourceForge bug # 123678. (idict.c [1.3]:
2000/11/30 07:13:08 lpd)
	- Further tweaking of the logic to clear end_status flags in a
pipeline in the continuation of a procedure write, making it more aggressive
than the previous fix, but less aggressive than the original code. This is a
revised fix for Sourceforge bug 119777. (zfproc.c [1.7]: 2000/12/02 19:58:45
raph)
	- 'gstate' was allowed in global VM even if the current graphics
state included references to structures in local VM (which is, in fact,
normally the case) and the save level was non-zero: this could create a
dangling pointer after the 'restore'. This "fix" is a workaround that simply
prohibits doing this, but a correct fix would copy any such structures.
(zdps1.c [1.3]: 2000/12/02 20:39:37 lpd)
	- The first call of check_psc_function in gs_build_function_4 didn't
initialize size to 0, causing the computed value of size to be garbage,
possibly leading to a VMerror or memory corruption. (zfunc4.c [1.7]:
2000/12/03 16:56:31 alexcher)
	- The font_info procedure for PostScript fonts other than Type 1
didn't return information from the FontInfo dictionary (Copyright,
FamilyName, FullName, Notice), causing this information to be omitted when
embedding the font in a PDF file. (ifont.h [1.6], zbfont.c [1.7],
zfont.c [1.3], zfont1.c [1.9]: 2000/12/03 23:35:30 lpd)
	- The %%ViewingOrientation: DSC comment was misspelled
%%ViewerOrientation:. This also corrects the CDSC_VIEWINGORIENTATION enum
value (formerly CDSC_VIEWERORIENTATION, and the viewing_orientation members
of the CDSCPAGE structure and the CDSC structure (formerly
viewer_orientation). (dscparse.c [1.3], dscparse.h [1.3], zdscpars.c [1.8]:
2000/12/09 18:28:23 lpd)
	- Unitialized member of CDSCPAGE caused random crashes.
(dscparse.c [1.4]: 2000/12/13 07:18:46 alexcher)
	- systemdict was being created too small for LanguageLevel 3
systems. (It expanded properly, but left a sandbar.) (iinit.c [1.3]:
2000/12/26 04:25:54 lpd)
	- Expanding a permanent dictionary (systemdict or userdict)
destroyed the single-definition bookkeeping for names defined in that
dictionary, slowing down subsequent interpretation. (idict.c [1.4]:
2000/12/26 06:09:58 lpd)
	- Fix to dscparse.c for parsing DOS EPS files. Code now looks for
%!PS-Adobe- at the start of the PostScript section, not at the start of the
DOS EPS header. (dscparse.c [1.5]: 2000/12/28 01:45:01 ghostgum)

Collect some stray configuration related externs into iconf.h
(imain.c [1.3], imainarg.c [1.5]: 2000/11/04 06:12:02 rayjj)

branches: 1.1.2; Collect some stray configuration related externs into
iconf.h (iconf.h [1.1]: 2000/11/04 06:12:02 rayjj)

Add COMPILE_INITS information line to -h help output. (imainarg.c [1.6]:
2000/11/04 06:13:42 rayjj)

Adds DSC parsing capability to the PostScript interpreter, with an optional
'feature' to use the DSC Orientation comments to compensate for sloppy
PostScript producers that don't emit an appropriate setpagedevice command.
(lib/gs_dscp.ps [1.1], zdscpars.c [1.1]: 2000/11/05 18:33:52 lpd)

branches: 1.1.2; Adds DSC parsing capability to the PostScript interpreter,
with an optional 'feature' to use the DSC Orientation comments to compensate
for sloppy PostScript producers that don't emit an appropriate setpagedevice
command. (dscparse.c [1.1], dscparse.h [1.1]: 2000/11/05 18:33:53 lpd)

Polishes the DSC parser interface: improves comments and formatting, and
fixes a couple of very minor glitches. (zdscpars.c [1.2]: 2000/11/06
07:34:21 lpd)

branches: 1.3.2; ... and fixes an overlooked const discrepancy.
(zdscpars.c [1.3]: 2000/11/06 07:35:51 lpd)

branches: 1.2.2; Fix: The recently updated code for activating the DSC
comment parser had several local/global VM problems, causing invalidaccess
errors. (lib/gs_dscp.ps [1.2]: 2000/11/07 18:51:25 lpd)

Return code variables (code and comment_code) in zparse_dsc_comments(). need
to be signed. (zdscpars.c [1.4]: 2000/11/08 00:54:48 dancoby)

Rewrites .parse_dsc_comment to use the parameter list machinery, removing a
little functionally duplicated code; changes two incorrect uints to ints
(fix from dan@artifex.com); adds additional comment types (BoundingBox,
PageBoundingBox, BeginDefaults, EndDefaults) to the interface.
(zdscpars.c [1.5]: 2000/11/08 07:07:32 lpd)

DSC parser changes: adds %%ViewerOrientation to DSC parser; doesn't flag an
error if %%Pages is absent but one %%Page is found; frees memory if
initialization fails; recognizes general whitespace in some places where
only spaces were recognized before. (changes from gsview@ghostgum.com.au)
(dscparse.c [1.2], dscparse.h [1.2]: 2000/11/13 05:44:58 lpd)

Adds DSC comment tracing to ps2pdf, if -dDEBUG is specified on the command
line. (lib/gs_pdfwr.ps [1.9]: 2000/11/13 17:03:51 lpd)

Adds %%EndDefaults, %%For:, and %%ViewerOrientation: to the set of DSC
comments handled by the .parse_dsc_comments operator. (zdscpars.c [1.6]:
2000/11/13 17:06:18 lpd)

Slightly simplifies the code for creating the internal representation of
CMaps. (lib/gs_cmap.ps [1.8]: 2000/11/16 00:32:00 lpd)

Changes .buildshading to always apply a ReusableStreamDecode filter to file
and stream DataSources, so that multiple passes over the stream work. This
patch closes SourceForge bug 121810. (lib/gs_ll3.ps [1.7]: 2000/11/16
00:37:32 raph)

Makes single-byte CMap ranges convert into a single range in the internal
representation, rather than (largest - smallest + 1) separate single-element
ranges. (lib/gs_cmap.ps [1.10]: 2000/11/29 07:10:27 lpd)

Adds documentation for the procedures declared in ifont.h. (ifont.h [1.5]:
2000/12/03 23:14:28 lpd)

Extensively revises and updates the pdfwrite text handling code to support
processing and embedding of all types of fonts (except for Type 3 and
CIDFontType 1, which are defined by PostScript procedures), and all variants
of 'show' (including kshow and glyphshow). In particular, Type 0 fonts with
all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both
standard and non-standard CMaps are supported. (lib/gs_cidfn.ps [1.18]:
2000/12/08 23:35:38 lpd)

Makes the default value of ParseDSCCommentsForDocInfo true rather than
false. (lib/gs_pdfwr.ps [1.10]: 2000/12/09 08:00:52 lpd)

Changes the parsing of the DSC Orientation comments to return -1 .. 3 rather
than 0 or 1. (lib/gs_dscp.ps [1.3], zdscpars.c [1.7]: 2000/12/09 17:52:29
lpd)

Changes .parse_dsc_comments to distinguish (document default)
ViewingOrientation from PageViewingOrientation, as for [Page]Orientation.
(zdscpars.c [1.9]: 2000/12/09 19:52:49 lpd)

Updates the comments with a new proposal for speeding up name lookup in the
interpreter. (dstack.h [1.3]: 2000/12/26 01:20:58 lpd)

The old code caused gswin crash when console window closes.
(dwimg.cpp [1.3]: 2000/12/26 13:41:40 igorm)

New flag DELAYSAFER added to defer activation of safety checks. SAFER=false
=> no safety checks SAFER=true, DELAYSAFER=false => safety checks
always SAFER=true, DELAYSAFER=true => safety checks after .setsafe
(lib/gs_init.ps [1.28]: 2000/12/29 04:13:56 alexcher)


Streams

Fixes problems:
	- Seek was broken and PDF interpreter failed when
FILE_IMPLEMENTATION=fd The implementation of streams using direct OS calls
is extended to support MSVC && Win32. close_.h is replaced by more
general unistd_.h (sfxfd.c [1.6]: 2000/12/19 03:35:40 alexcher)


Library

Fixes problems:
	- Several places in the band list code didn't call s_init_state to
initialize locally allocated stream states: this is now required (see the
"Incompatible changes" section above). We suspect there are a few more
places that will need this fix. (gxclbits.c [1.3], gxcldev.h [1.4],
gxclread.c [1.3], gxclutil.c [1.3]: 2000/11/05 00:34:24 lpd)
	- Fixes infinite loops when writing large bitmaps into clist. Now,
cmd_put_bits never requests an allocation in the clist buffer larger than
cbuf_size. (gxclbits.c [1.4]: 2000/11/05 18:44:57 raph)
	- Works around an Acrobat Reader 4 bug that causes AR4 to draw a
single pixel, rather than nothing, when filling a subpath consisting only of
a moveto. (gdevvec.c [1.8]: 2000/11/07 16:42:28 lpd)
	- The PDF writer didn't handle stroked fonts correctly (they were
filled instead of stroked). (gdevvec.c [1.9], gdevvec.h [1.5]: 2000/11/12
06:52:08 lpd)
	- The pdfwrite and pswrite drivers could emit a lineto or rlineto
without a moveto at the beginning of the path. (bug introduced very
recently, by a workaround for an Acrobat Reader bug) (gdevvec.c [1.10]:
2000/11/14 07:41:08 lpd)
	- Attempting to write a CFF Type 2 font larger than 32K but smaller
than 64K caused a rangecheck. (gdevpsf2.c [1.8]: 2000/11/19 17:48:08 lpd)
	- Computing the default width or the fixed width for a CIDFont or
TrueType font could do a huge amount of unnecessary work. (Probably only
affects the PDF writer.) (gsfont.c [1.3]: 2000/11/20 21:09:09 lpd)
	- The Type 1 to Type 2 CharString converter (currently used only by
the PDF writer) often didn't detect invalid CharStrings as input.
(gdevpsfx.c [1.6]: 2000/11/21 02:33:55 lpd)
	- The code for writing a CIDFontType0 CFF font mistook Type 2
CharStrings for Type 1, and tried to convert them to Type 2. (This currently
affects only the PDF writer.) (gdevpsf2.c [1.9]: 2000/11/21 02:35:59 lpd)
	- Disk-based TrueType fonts caused a memory leak. (Currently, there
are no such fonts, but CIDFontType 2 fonts, and directly-accessed TrueType
fonts, should be made disk-based.) (gdevpsft.c [1.5], gstype42.c [1.10]:
2000/11/22 08:32:07 lpd)
	- Type 1 CharStrings loaded from disk for type 0 CIDFonts were never
freed, except by garbage collection (which doesn't reclaim chunks with only
a small amount of surviving data). In practice, this probably only affects
the PDF writer. (gsfcid.c [1.5], gstype1.c [1.6], gstype2.c [1.9],
gxfont1.h [1.5], gxtype1.c [1.8], gxtype1.h [1.5]: 2000/11/23 23:34:22 lpd)
	- The pswrite device couldn't write to pipes. The fix involved
expanding the API for opening device OutputFiles so that the individual
driver could specify whether it required, requested, or did not want a
positionable file. Fixes SourceForge bug # 122223. (gdevpipe.c [1.4],
gdevvec.c [1.11], gdevvec.h [1.6], gsdevice.c [1.8]: 2000/11/29 02:25:13
lpd)
	- The change for freeing transient CharStrings introduced two bugs,
possibly causing the code to free data twice, or to free data that should be
retained. (gdevpsfx.c [1.8]: 2000/11/30 05:58:19 lpd)
	- Allocates graphics state path in stable memory. This prevents
paths in Type 3 fonts allocated inside a save ... setcachedevice ... restore
sequence from being prematurely freed. Fixes SourceForge bug 101549.
(gspath1.c [1.3], gsstate.c [1.6]: 2000/12/04 21:13:55 raph)
	- An inadvertent change caused the graphics state not to be freed on
grestore. This fix, due to lpd, restores the freeing statement.
(gsstate.c [1.7]: 2000/12/05 09:24:57 raph)
	- The pointers to the substituted color spaces in the graphics state
weren't included in the structure descriptor, causing memory access errors
if UseCIEColor was used. (gsstate.c [1.8]: 2000/12/11 04:06:22 alexcher)
	- In TrueType fonts, glyph outlines starting with an off-curve point
didn't render correctly, replacing the curve with a pair of straight lines.
(gstype42.c [1.11]: 2000/12/12 22:27:56 alexcher)
	- Strict type correctness is required on VMS system. Contributed by
Jouk Jansen joukj@hrem.stm.tudelft.nl (gdevpsf2.c [1.12], gsfcmap.c [1.13]:
2000/12/18 21:58:03 alexcher)
	- Seek was broken and PDF interpreter failed when
FILE_IMPLEMENTATION=fd The implementation of streams using direct OS calls
is extended to support MSVC && Win32. close_.h is replaced by more
general unistd_.h (gpmisc.c [1.9]: 2000/12/19 03:35:40 alexcher)
	- Fixes a subtle logic bug in the scan line path filling code, which
unfortunately involved rewriting the code from scratch. The new code is also
somewhat subtle, and may contain new bugs: DON'T TRUST IT YET. Fixes
SourceForge bug # 117066. (gxfill.c [1.7]: 2000/12/23 06:02:39 lpd)
	- Embedded Type 1 fonts omitted StdVW. (Acrobat Reader requires
this, even though the Type 1 specification says it is optional.)
(gdevpsf1.c [1.8]: 2000/12/29 01:18:55 lpd)

Adds developer documentation on the color mapping pipeline. (gxfrac.h [1.3]:
2000/11/03 04:53:00 lpd)

procedure in a text enumerator. (gxtext.h [1.6]: 2000/11/06 00:44:37 lpd)

Adds a param_string_from_transient_string macro, to parallel
param_string_from_string for non-permanent C strings. (gsparam.h [1.8]:
2000/11/08 06:56:50 lpd)

Adds a macro for declaring suffix subclasses with 5 added pointers (in
addition to the existing 1, 2, 3, 4, and 6). (gsstruct.h [1.6]: 2000/11/21
16:46:55 lpd)

Adds a procedure for testing whether a glyph is a "notdef" in a font,
necessary for fixing a memory consumption problem when accessing type 0
CIDFonts. (gsfont.c [1.4], gxfont.h [1.3]: 2000/11/23 23:23:40 lpd)

Speeds up the slow case of fixed_mult_quo by nearly a factor of 2, by using
a tiny bit of numerical analysis. (gsmisc.c [1.9], gxfixed.h [1.3]:
2000/11/24 06:53:23 lpd)

Improves the performance of embedded font writing by freeing strings when no
longer needed, and by removing redundant computation. (Currently relevant
only to the PDF writer.) (gdevpsf1.c [1.7], gdevpsf2.c [1.10],
gdevpsfu.c [1.5], gdevpsfx.c [1.7]: 2000/11/24 07:10:41 lpd)

Adds a procedure for creating an Identity CMap, needed by the PDF writer.
(gsfcmap.c [1.11], gxfcmap.h [1.6]: 2000/11/26 04:08:41 lpd)

Implements the stopgap measure of increasing fill_adjust for Coons patch
shading, to cover the dropouts caused by incorrect triangulation of the mesh
surface. See SourceForge Bug 119588 for a more thorough analysis.
(gsptype2.c [1.4], gxshade4.c [1.4]: 2000/11/29 01:31:30 raph)

Adds an internal unique ID to CMap structures (gs_cmap_t), for use as a
cache or comparison key. (gsfcmap.c [1.12], gxfcmap.h [1.7]: 2000/11/29
05:50:03 lpd)

The old code did not comply ISO/IEC C language standard and compiled wrongly
to Mac, causing halftone problem on Mac. (gshtscr.c [1.5]: 2000/11/29
14:41:34 igorm)

Adds macros for suffix subclass structures with 7 or 8 additional pointers
(1-6 and 9 existed already). (gsstruct.h [1.7]: 2000/12/04 01:11:53 lpd)

Extensively revises and updates the pdfwrite text handling code to support
processing and embedding of all types of fonts (except for Type 3 and
CIDFontType 1, which are defined by PostScript procedures), and all variants
of 'show' (including kshow and glyphshow). In particular, Type 0 fonts with
all FMapTypes (including CMap-based), CIDFontType 0 and 2 fonts, and both
standard and non-standard CMaps are supported. (gdevpsf.h [1.9],
gdevpsf2.c [1.11], gdevpsfm.c [1.4], gdevpsft.c [1.6], gdevpsfu.c [1.6]:
2000/12/08 23:35:38 lpd)

Moves definitions of gs_state_do_ptrs and gs_state_num_ptrs from gsstate.c
to gzstate.h since they depend on the contents of struct gs_state_s defined
there. (gsstate.c [1.9], gzstate.h [1.4]: 2000/12/11 12:52:16 alexcher)

Splits off the code for downsampling an oversampled character bitmap into a
separate file. (gsbitcom.c [1.1], gsbitops.c [1.3]: 2000/12/14 00:14:52 lpd)

branches: 1.1.2; Fix: Seek was broken and PDF interpreter failed when
FILE_IMPLEMENTATION=fd The implementation of streams using direct OS calls
is extended to support MSVC && Win32. close_.h is replaced by more
general unistd_.h (unistd_.h [1.1]: 2000/12/19 03:35:40 alexcher)

Brings gxfill.c up to date with current coding standards (except for adding
_t to the names of locally defined structure types); also puts #ifdef
FILL_TRAPEZOIDS around a little more code that tests 'if (fill_trapezoids)'.
(gxfill.c [1.6]: 2000/12/21 16:10:36 lpd)

Updates repository for 6.60 release. (gscdef.c [1.11]: 2001/01/01 00:24:06

Procedures

Fixes problems:
	- The PostScript image writing drivers (psmono/gray/rgb) didn't set
the page size in the output, and didn't produce DSC-compliant output.
(devs.mak [1.31]: 2000/08/09 06:55:45 lpd)
	- The FlateEncode and zlibEncode filters didn't implement the
"Effort" parameter. (fix from Alex Cherepanov) (int.mak [1.28]: 2000/08/09
16:55:24 lpd)
	- Because "-" as an OutputFile now references the %stdout IODevice,
it no longer worked in configurations without a PostScript interpreter.
Fixing this required factoring out the stdin/out/err IODevices and providing
an implementation that didn't reference the PostScript interpreter.
(int.mak [1.32], lib.mak [1.34], ugcclib.mak [1.3]: 2000/09/07 06:14:45 lpd)
	- Configurations including PDF but not PostScript didn't include all
the PostScript LL3 features needed to interpret PDF 1.3 et seq.
(int.mak [1.33]: 2000/09/07 06:35:06 lpd)
	- Cleans up some missing and incorrect dependencies.
(devs.mak [1.33], int.mak [1.34], lib.mak [1.35]: 2000/09/11 04:43:09 lpd)
	- The definition of PSRCDIR was inconsistent with the definition of
PVERSION. (openvms.mak [1.5]: 2000/09/22 04:05:40 lpd)
	- The pgnm and pnm drivers didn't properly detect the presence of
gray shades or color in images, sometimes causing gray or color information
to be lost in the output. (fix contributed by a user) (devs.mak [1.35]:
2000/09/23 04:52:56 lpd)

Initializes files for the 6.24 fileset. (version.mak [1.19]: 2000/08/09
16:54:02 lpd)

Adds a mention of the Color LaserJet 4500 as a color PCL XL printer.
(devs.mak [1.32]: 2000/08/17 20:43:50 lpd)

Changes text to make it clear that Yves Arrouye no longer maintains the BJC
drivers that he wrote. (contrib.mak [1.19]: 2000/08/21 14:38:28 lpd)

Puts the logic for detecting garbage after %%EOF (and some similar invalid
constructs) back into the main code, making it produce a message on stderr.
(unixinst.mak [1.12]: 2000/08/23 02:22:39 lpd)

Starts to implement the PDF 1.4 transparency features. All API and operator
additions are now implemented (at least as stubs) and documen
