遗传算法工具箱 希望高手指点 GATOOLS

-----------

Fixes bugs:
	- The default operator array table wasn't big enough.  (iinit.c)
	- Some signed/unsigned discrepancies caused compilation warnings.
(imain.c, imainarg.c, zfile.c)

Adds encoding vectors for Windows 3.1 Latin 1, Latin 2, and Latin 5
encodings.  None of these are loaded in the standard configuration.
(gs_wl{1,2,5}_e.ps)

Library
-------

Fixes bugs:
	- Some tracing output was incorrect or missing.  (gxdither.c)
	- Resized objects in the C heap had incorrect bookkeeping
information (bug introduced in 3.68).  (gsmemory.c)
	- Image pixels that fell exactly on device half-pixel boundaries
could get discarded.  (gximage0.c)
	- The bounding box device didn't set a variable properly and didn't
implement end_image, leading to invalid memory accesses.  (gdevbbox.c)
	- Fonts with BuildChar routines written in C didn't work properly
with kshow or xyshow.  (gschar.c)

Adds some additional tracing output for Patterns.  (gxpcmap.c)

gs_flattenpath expands curves.  (gspath.h, gspath1.c)

Version 3.68 patch 3 (5/17/96)
====================

More bug fixes during the beta test period.  AccurateScreens now works
properly.

Procedures
----------

Fixes bugs:
	- The help message was too long to fit on a PC screen or standard
terminal.  (imainarg.c)
	- Failure to run tar_cat wasn't detected.  (unix-end.mak,
unixtail.mak)

Utilities
---------

Fixes bugs:
	- In the PostScript files produced by pdf2ps, images using ASCII85
encoding would cause a typecheck error.  (gs_pdf.ps)
	- pdf2ps wrote out strings longer than 200 characters incorrectly.
(pdf_2ps.ps)

Drivers
-------

Fixes bugs in gdevcdj.c (according to the author, we have no way to test
this):
	- The driver used to use Colors as well as ProcessColorModel to
define the process color model.  (devices.doc, gdevbjc.h, gdevcdj.c)
	- Incorrect or inconsistent settings of BitsPerPixel and
ProcessColorModel, or setting one but not the other, could leave the driver
in an inconsistent state.  (gdevcdj.c)

Fixes bugs in the MS Windows driver:
	- Insufficient memory for the backing bitmap could cause a GPF.
(gdevmswn.c, gdevwdib.c)
	- Invalid parameters could cause a crash within the DLL code.
(gdevwdib.c)

Adds a user-contributed driver for the CalComp Raster Format.  (devs.mak,
gdevccr.c)

Adds an anti-aliasing option for MS Windows.  (gdevmswn.c, gdevwdib.c)

Platforms
---------

Fixes bugs in the Windows platform:
	- One had to type "quit" twice to exit.  (dwdll.h, dwdll.cpp)

Interpreter
-----------

Fixes bugs:
	- Platform fonts didn't work properly if the document's primary
encoding was the standard MS Windows encoding.  (ifont.h, gs_wan_e.ps)
	- stringwidth with a Type 1 font could give a spurious typecheck
error (bug introduced in 3.65).  (zcharout.c)
	- If a DOS editor added a ^Z to the end of the Fontmap file, an
error occurred during initialization.  (gs_fonts.ps)
	- Halftones that didn't specify a value for AccurateScreens
sometimes ignored the setting of the AccurateScreens user parameter.
(zht2.c)

Library
-------

Fixes bugs:
	- gs_join_none was defined, but not implemented.  (gxstroke.c)
	- A bookkeeping list for fonts could get confused, causing invalid
memory accesses.  (gsfont.c)
	- An I/O error or internal error would cause the band list
rasterizer to go into an infinite loop.  (gxclread.c)
	- The algorithm for choosing screen angles and frequencies produced
poor results.  (gshtscr.c)
	- Color screens were broken (bug introduced in 3.68).  (gxdht.h,
gzht.h, gsht.c, gshtscr.c)

Version 3.68 patch 2 (5/13/96)
====================

This is another set of patches for the next general release.

Documentation
-------------

Fixes bugs:
	- Windows NT and Windows 95 implementations were identified as
"under development" rather than available.  (README)
	- There were several other minor errors in the README file.
(README)
	- The claimed current IJG JPEG version was incorrect.  (jpeg.mak)

Splits off information for new users into a separate file.  (README,
new-user.doc)

Procedures
----------

Fixes bugs:
	- gettimeofday takes 2 arguments on SVR4 systems more recent than
SVR4.0.  (make.doc, ansihead.mak, cc-head.mak, gcc-head.mak, time_.h)

Changes the default Unix data installation directory from /usr/local/lib to
/usr/local/share, which seems to be favored by more recent Unix systems
(except for some Linux versions, which still use /usr/local/lib, and BSD/OS,
which puts Ghostscript in /usr/contrib/lib.)  (ansihead.mak, cc-head.mak,
gcc-head.mak, ugcclib.mak)

Changes the unset commands in the Unix script to assignments, because a few
older Unix shells don't provide unset.  (unixtail.mak)

Drivers
-------

Fixes bugs:
	- An #include incorrectly referred directly to a system header.
(gdevpdft.c)
	- CMYK devices took an excessive amount of time clearing the page to
white.  (gdevm32.c)

Adds a compile-time option to the 'bit' drivers to remove top and bottom
whitespace.  This change was required in order to track down a customer bug.
(gdevbit.c)

Interpreter
-----------

Updates the interpreter for the split in the gstate API.  (igstate.h)

Streams
-------

Fixes bugs:
	- Some compilers don't define NULL widely enough.  (spngp.c)

Library
-------

Fixes bugs:
	- There was a minor typo (& for &&) that didn't affect execution.
(gxccman.c)
	- There was a trailing comma in an enumeration.  (gsiparam.h)
	- Internal and public interfaces weren't separated properly.  THIS
IS A NON-BACKWARD-COMPATIBLE CHANGE for clients using certain undocumented
interfaces to the graphics state.  (gsstate.h, gxstate.h, gzstate.h,
gsstate.c)
	- A 'private' declaration was missing (yet again).  (gxclimag.c)

Version 3.68 patch 1 (5/10/96)
====================

This is the first bug fix (patch) incremental release for the next general
release.

Procedures
----------

Fixes bugs:
	- Many Windows-specific files were omitted from the previous
fileset: dw*.rc, dw*.cpp.

Version 3.68(limited) (5/9/96)
=====================

This release cleans up the new Windows files, mostly implements the
high-level driver API for bitmap images, and adds practical strip
(AccurateScreens) halftoning.  This is the first "serious beta" fileset for
the next general release.  It still has more problems than I would have
liked.

Documentation
-------------

Fixes bugs:
	- The names of the executable files for MS Windows were out of date.
(make.doc)
	- gxcindex.h still referred to "drawing color".  (gxcindex.h)
	- The name of the default font directory for Unix systems was
incorrect.  (make.doc)

Moves the list of files required for installation, and some other
installation instructions, from make.doc to install.doc.  (install.doc,
make.doc)

Adds a description of the PNGPredictor filters.  (language.doc)

Updates the documentation of the higher-level driver procedures to match the
specification changes.  (drivers.doc)

Documents the change in the Watcom build procedure.  (make.doc)

Improves the documentation of bitmap IDs.  (gxbitmap.h)

Adds documentation for the new strip_tile_rectangle and strip_copy_rop
driver procedures.  (drivers.doc)

Changes the few remaining direct FTP addresses in README to URLs.  (README)

Notes that zlib does not compile correctly on IRIX 6.n with optimization.
(make.doc)

Adds references to PDF and TrueType fonts to language.doc.  (language.doc)

Updates fonts.doc to remove references to fonts.mak.  (fonts.doc)

Describes how to substitute an LZW compressor for the LZW-compatible
compressor provided in the standard release.  (make.doc)

Procedures
----------

Fixes bugs:
	- Some lines had exceeded the 120-character limit of the
MS-DOS shell.  (int.mak)
	- The configuration files weren't generated correctly when CONFIG
wasn't an empty string.  (unixhead.mak)

Factors out shared DLL makefile rules into a new file.  (bcwin.mak,
bcwin32.mak, dwcommon.mak)

Makes the cp and rm commands into makefile parameters, allowing automatic
generation of build scripts even in the MS-DOS and MS Windows environments
where the shell requires the CALL command for sub-scripts.  (*.mak,
genconf.c)

Adds the PDF writer to the default Unix configurations.  (ansihead.mak,
cc-head.mak, gcc-head.mak)

Adds TrueType support to all Level 2 configurations.  (int.mak)

Removes fonts.mak, which is no longer relevant.  (fonts.mak)

Brings the font compilation procedures up to date.  (cfonts.mak, int.mak)

Utilities
---------

Fixes bugs:
	- There was an extra 'show' in one file.  (align.ps)

Drivers
-------

Fixes bugs:
	- The bit devices were missing the map_color_rgb procedure.
(gdevbit.c)
	- The MS Windows driver sent a redundant message. (gdevmswn.c)

Adds a device that keeps track of the page bounding box.  This device is not
included in any standard configuration.  (drivers.doc, gdevbbox.h,
gsmatrix.h, gsstruct.h, gxdevice.h, gdevbbox.c, gdevnfwd.c, gsmatrix.c)

Updates the PDF writer to track the changes in the high-level driver API,
and to write out images in a reasonable way.  NOTE: the current
implementation doesn't write out CIE color space parameters, so CIE-color
images won't be colored accurately.  (gdevpdf.c, gdevpdfi.c)

Adds a forwarding procedure for tile_rectangle.  (gxdevice.h, gdevnfwd.c)

Changes the copyright notices on the PDF writer to be the same as on the
rest of Ghostscript.  (gdevpdf*.[ch])

Updates Gunther Hess's Epson Stylus Color driver from 1.21 to 1.90.  (Aladdin
Enterprises takes no responsibility for this driver: if you have questions,
contact the author.)  (devices.doc, devs.mak, gdevstc*.c, gdevstc.h)

Platforms
---------

Removes some obsolete MS Windows files and #defines.  (gp_mswtx.h,
gp_mswtx.c, gp_mswin.h)

Works around a memory limitation in the Watcom make utility.  (wmakebat.bat)

Fonts
-----

Changes the standard Fontmap from using the low-quality fonts converted from
bitmaps to using high-quality fonts recently contributed by URW++.
(Fontmap, Fontmap.GS)

Interpreter
-----------

Fixes bugs:
	- A macro containing an if-else, and a macro generating a compound
statement, could cause incorrect grouping of 'if' statements.  (files.h,
ostack.h)
	- .setrasterop didn't pop its operand.  (zrop.c)
	- A rounding inaccuracy could cause bounding box rangecheck errors.
(gsdps1.c)
	- CIE-based images in PDF files didn't work.  (gs_pdf.ps)
	- The page parameter .MediaSize didn't get updated when PageSize was
set.  (This is just the most recent manifestation of the setpagedevice
morass.)  (gs_setpd.ps)
	- %lineedit and %statementedit were limited to 160 characters.
(zfileio.c, ziodev.c)
	- Compiled initialization files didn't work properly.  (geninit.c,
gs_l2img.ps)
	- Attempting to parse a command line with argc = 0 caused a crash.
(imainarg.c)

Renames some files to allow separating the non-DLL 'main' procedure into a
separate file, and to make the file naming more consistent:
	gs.c (except for 'main') => imainarg.c
	gsmain.c => imain.c
gs.c now consists only of 'main'.  The name gs.c is still inconsistent (it
should be i- something), but at least it's consistent with the name of the
executable.  (*.mak, imain.h, iminst.h, imainarg.h, gs.c, gsmain.c, imain.c,
imainarg.c)

Adds PNGPredictorEncode/Decode filters, and increases the size of filterdict
slightly to make room for them.  (iinit.c, zfpngp.c)

Makes zwrite external, per a customer request.  (opextern.h, zfileio.c)

Updates clients to work with the new API-based bitmap imaging calls.
(iimage.h, zcolor1.c, zimage2.c, zpaint.c)
