- *========================================================================
-
- This release adds the following features:
-
- * faster, more compact color Postscript printing. Color printers are just
- too cheap and plentiful these days to keep the old algorithms.
- Bob Tatar's colorImage operator has consequently been removed from
- xgrabsc. Though it is good code and quite general, it is very very slow.
- Direct conversion of the rgb table to luminesence values is now used
- instead.
-
- There are still some bugs in compressed binary color output, but I
- didn't want to hold up the release for them.
-
- * a Motif version of the user-interface. You have to mess with the
- makefile (Imakefile or simple.mak) to get the Motif version to build,
- and you MUST have Motif 1.2 or later to use that version of xgrab -
- the resource file uses 1.2 features.
-
- Both versions have had a "matrix" dither toggle button added.
-
- Unless I hear a big scream from you I will be dropping the Athena
- version in v2.4.
-
- * the encapsulated-postscript options in the window interface have been
- simplified. There are now only "Landscape" and "PS Figure" options.
-
- * a "-coords" selection mode contributed by Matthew Freedman. This
- selection mode lets you specify the exact area to be grabbed. Pre and
- Post grab sleeping still applies, but there is no keyboard or mouse
- interaction.
-
- * if you specify an output file name with "-o", xgrabsc now puts a
- %%File comment in Postscript output showing the name of the file the
- image was written to.
-
- * the resource files for the xgrab program are now run through xrdb
- (and consequently the C preprocessor) to set the proper defaults for
- page sizes and other settings from the config.h include file. There
- are new entries at the bottom of config.h for these resources.
-
- * XWD style output for black & white images used to pack eight pixels per
- output byte. This has been changed so that output is one pixel per byte,
- just like the xwd program. A new option "-xwdxy" has been added to
- give the packed style output and is equivalent to the "-xy" option
- for the xwd program. The unpacked format has not been extensively
- tested.
-
-
- and this release fixes the following bugs:
-
- * the man page for xgrabsc said it accepts "-output" but it accepted only
- "-o" or "-out". It now accepts all three.
-
- * NewsPrint had trouble with the "/max" definition in the CheckVM operator.
- It has been changed to "/maximum" as recommended by Joe Ramey.
-
- * several people reported that for little-endian machines (e.g.,
- DECStations) the XWD-writing code was swapping the bits of the size of
- the colormap before padding the output colormap with blacks. This
- resulted in very large output.
-
- * XWD output for dithered images from color displays on screens with
- Black==1 (e.g., color HPUX 9.0 tubes) was giving reversed images when
- displayed with xwud on the same screen. I wish MIT would require
- Black to be 0 in all servers - it would make life a bit easier.
-
- * XScreenNumberOfScreen not found in Xlib on HP's. Xgrabsc now has its
- own copy of this function
-
- * Dumping of subwindows in earlier releases just didn't work at all. In
- this release, you can dump any window by ID.
-
- * Preview images in EPSI files were using 1 for white and 0 for black.
- The EPSF v2.0 spec states that "In the preview section, bits of 0 are
- white, bits of 1 are black". FrameMaker follows this but some releases
- of xfig do not, so I've added a configuration option in config.h and
- made the default follow the standard.
-
- * xgrabsc was always looking at the root window for the colormap of an
- image, even if point-and-click or window-id dumps were selected. It
- now gets the first colormap in the installed colormaps of the target
- window.
-
- * color postscript routines were leaving items on the stack after reading
- an image's color table. This could mess up postscript programs using
- xgrabsc files.
-
- * dithering operations were failing with displays having Black=1. Fixing
- this has unfortunately exposed a bug in xwud. If xwud will display the
- images with reversed colors. xpr will display them properly
-
- * postscript output now always includes %!PS-Adobe-2.0 and %%EndProlog
- lines
-
- * postscript preview output did not always indicate the correct number of
- lines
-
- * postscript previews sometimes had an erroneous blank line between data
- and %%EndPreview
-
- * The -reverse option was only working for color images. It now works for
- black and white images also.
-
- * XPM3 format was not using the output file name in forming a name for
- the image structure
