Newsgroups: comp.sources.misc From: jef@well.sf.ca.us (Jef Poskanzer) Subject: REPOST: v23i036: pbmplus - Extended Portable Bitmap Toolkit, Part01/24 Message-ID: <1991Oct15.015451.16314@sparky.imd.sterling.com> X-Md4-Signature: 6af94d7cfa30f80c75087ba750b38c52 Date: Tue, 15 Oct 1991 01:54:51 GMT Approved: kent@sparky.imd.sterling.com Submitted-by: jef@well.sf.ca.us (Jef Poskanzer) Posting-number: Volume 23, Issue 36 Archive-name: pbmplus/part01 Environment: UNIX Extended Portable Bitmap Toolkit Distribution of 27sep91 Previous distribution 05feb91 PBMPLUS is a toolkit for converting various image formats to and from portable formats, and therefore to and from each other. The idea is, if you want to convert among N image formats, you only need 2*N conversion filters, instead of the N^2 you would need if you wrote each one separately. In addition to the converters, the package includes some simple tools for manipulating the portable formats. The package is broken up into four parts. First is PBM, for bitmaps (1 bit per pixel). Then there is PGM, for grayscale images. Next is PPM, for full-color images. Last, there is PNM, which does content-independent manipulations on any of the three internal formats, and also handles external formats that have multiple types. The parts are upwards compatible: PGM reads both PGM and PBM files and writes PGM; PPM reads all three and writes PPM; and PNM reads all three and writes, usually, the same type as it read. Whenever PNM makes an exception and "promotes" a file to a higher format, it lets you know. I've tested this stuff under SysV and BSD, on Sun 3's 4's and 386's and Sequents and Vaxen and HPs, with cc and gcc. Nevertheless, I'm sure bugs remain, and portability to systems like Amigas and IBM compatibles is an interesting question. Feedback is welcome; send bug reports, enhancements, etc. to this address: jef@well.sf.ca.us {apple, ucbvax}!well!jef When sending bug reports, always include the output from running any PBMPLUS program with the -version flag. Also include the type of system you are on, what compiler you used, and whether you are using Makefiles or Imakefiles. I try to respond to bug reports and enhancements promptly; say, within a week. Finally, if you have access to Usenet, there's a newsgroup called alt.graphics.pixutils which is specifically for discussion of image conversion and editing packages such as PBMPLUS. Posting stuff there is even better than mailing it to me, since it lets other people help out with the answers. ----- #! /bin/sh # This is a shell archive, meaning: # 1.

The idea is, Xif you want to convert among N image formats, you only need 2*N Xconversion filters, instead of the N^2 you would need if you wrote each Xone separately. X XIn addition to the converters, the package includes some simple tools Xfor manipulating the portable formats. X XThe package is broken up into four parts. First is PBM, for bitmaps (1 Xbit per pixel). Then there is PGM, for grayscale images. Next is PPM, Xfor full-color images. Last, there is PNM, which does content-independent Xmanipulations on any of the three internal formats, and also handles Xexternal formats that have multiple types. X XThe parts are upwards compatible: PGM reads both PGM and PBM files and Xwrites PGM; PPM reads all three and writes PPM; and PNM reads all three Xand writes, usually, the same type as it read. Whenever PNM makes an Xexception and "promotes" a file to a higher format, it lets you know. X X XINSTALLATION X X Unpack the files. X Decide whether you want to use Imakefiles or Makefiles. If you want X to use Makefiles: X X Edit the top-level Makefile, find each line with the string X "CONFIGURE", and follow the directions for setting configuration X options. X Likewise edit pbmplus.h. X If you are using gnu make, you have to edit *all* the Makefiles X and remove all the imake stuff at the ends, otherwise gnu make X will overwrite the Makefiles. X Make. X When you're happy that things compiled ok, make install. X X The Imakefiles are pretty minimal, but if you want to use them anyway: X X Edit pbmplus.h, find each line with the string "CONFIGURE", and X follow the directions for setting configuration options. X Save the original Makefiles, in case you later want to switch back X to using them. X The usual X11 sequence of xmkmf, make Makefiles, make depend, then X make should work. X When you're happy that things compiled ok, make install and X make install.man. X XAfter installing the manual pages, you may want to create the "whatis" Xfile by doing a catman -w -M <directory>, or whatever the equivalent is Xon your system. X X XSUPPORT X XI've tested this stuff under SysV and BSD, on Sun 3's 4's and 386's and XSequents and Vaxen and HPs, with cc and gcc. Nevertheless, I'm sure bugs Xremain, and portability to systems like Amigas and IBM compatibles is Xan interesting question. Feedback is welcome; send bug reports, Xenhancements, etc. to this address: X X jef@well.sf.ca.us X {apple, ucbvax}!well!jef X XWhen sending bug reports, always include the output from running any XPBMPLUS program with the -version flag. Also include the type of Xsystem you are on, what compiler you used, and whether you are using XMakefiles or Imakefiles. I try to respond to bug reports and enhancements Xpromptly; say, within a week. X XAlso, if there is a new format or feature you would like to have added Xto the package, feel free to drop me a line. If it's a format, include Xwhatever documentation you have, and if possible a uuencoded sample. XMy response time will depend on how busy I am, and how easy the job Xlooks. If you need it right away, or it's a complicated job, you might Xconsider paying me; lately, that's how a lot of work on the package has Xgotten done. X XFinally, if you have access to Usenet, there's a newsgroup called Xalt.graphics.pixutils which is specifically for discussion of image Xconversion and editing packages such as PBMPLUS. Posting stuff there Xis even better than mailing it to me, since it lets other people help Xout with the answers. X X XHOW TO FIND THE RIGHT CONVERTER X XSome people get confused by all the different names. If you want to Xconvert a pbm file to a Sun raster file, is it pbmtorast, pgmtorast, Xppmtorast, or pnmtorast? In this case some of the confusion might be Xbecause previous versions of the package did in fact have both Xpbmtorast and ppmtorast. But mostly it's just too many different Xthings to hold in your short term memory. Fine, so don't even try to Xremember what's what. That's what computers are for. Unix, at least XBSD Unix, has this great indexing feature on the "man" program. You Xsay "man -k <keyword>" and it gives you all the one-line descriptions Xwith that keyword in them. All the PBMPLUS man pages have nice useful Xone-line descriptions, that mention all the relevant keywords. Try it, Xyou'll like it. X X XCOPYRIGHTS X XAll the software in this package, whether by me or by a contributer, Xhas a copyright similar to this one: X X Permission to use, copy, modify, and distribute this software and its X documentation for any purpose and without fee is hereby granted, provided X that the above copyright notice appear in all copies and that both that X copyright notice and this permission notice appear in supporting X documentation. This software is provided "as is" without express or X implied warranty. X XMany people get confused by this legalese, especially the part about X"without fee". Does this mean you can't charge for any product that Xuses PBMPLUS? No. All it means is that you don't have to pay me. XYou can do what you want with this software. Build it into your Xpackage, steal code from it, whatever. Just be sure to let people Xknow where it came from.

Datri, Arthur David Olson, David Brooks, X David Elliott, Doug Claar, Duncan Sinclair, Francois Pinard, Gerard X Leurs, Jim Hanko, Ken Laprade, Klaus U. Schallhorn, Markus Bolz, Mike X Hench, Philip Gladstone, R C Smith, Selden E. Ball, Jr., Stephen Uitti, X Steve Allen, Tom Lane, update.kpj-jaakkola@athena.dsv.su.se, X Charles Karney, Unmesh Agarwala, Ed Pendzik, Juha Sarlin, Tom Tulinsky, X Phillip Smith, Lai-King Mau, David Koblas, Mark Donovan. X Added a global -version flag. X Added bunches of statics and prototypes. Now compiles with zero X warnings under gcc -ansi -pedantic. X Changed #ifdef __STDC__ to #if __STDC__, since some non-compliant X compilers define it as 0. X Changed pm_message and pm_error to be varargs routines. Added a X portable version of vfprintf for those systems which don't have it. X Removed the option of not compiling the pgm and ppm parts. Very few X people used it, and it added amazing complexity to the pnm programs, X turning them into maintenance nightmares. X Merged pbmpaste into pnmpaste. X Merged pgmtops and ppmtops into pnmtops. X Added auto-scaling and dpi / page size flags to pnmtops. X Changed the interpretation of bits in pbmlife to conform with other X tools. X Changed xwdtopnm to ignore the pixel number in the xwd color structure. X Added a -pseudodepth flag to pnmtoxwd. X Updated tifftopnm for libtiff 2.4. X Added many option flags to pnmtotiff. (J.T. Conklin) X Added support for X11R5's new color specifiers rgb: and rgbi:. X Added pgmtexture. (James Darrell McCauley) X Added ppmtopj, pjtoppm, and ppmdither. (Christos Zoulas) X Added ppmtotga. (Mark Shand) X Added ppmtosixel. (Rick Vinci) X Added pbmtoatk and atktopbm. (Bill Janssen) X Added ppmtoyuv and yuvtoppm. (Marc Boucher) X Fixes to picttoppm. (George Phillips) X Added 24-bit support to ilbmtoppm. (Mark Thompson) X XChanges since the X.V11R4 / comp.sources.misc distribution of 22nov89: X X Added pgmramp, pgmedge, pgmtoppm, rgb3toppm, ppmtoxpm, pnmgamma, X ximtoppm, pgmtofs, picttoppm, ppmtopict, ppmquantall, anytopnm, X pi1toppm, ppmtopi1, sputoppm, spctoppm, pbmto10x, ppmtoicr, ppmmake, X xpmtoppm, ppmtopuzz, ppmtouil, ybmtopbm, pbmtoybm, lispmtopgm, X pgmtolispm, pbmtogem, pi3topbm, pbmtopi3, pbmtoepson, pbmtoplot, X pbmtozinc, pbmtext, pnmnoraw, pnmmargin, pnmfile, pnmindex, X ppmtorgb3, gouldtoppm, pgmbentley, pgmoil, ppmrelief, pnmtotiff, X ppmtopcx. X Merged some filters: X rasttopbm and rasttoppm into rasttopnm; X pbmtorast and ppmtorast into pnmtorast; X xwdtopbm and xwdtoppm into xwdtopnm; X pbmtoxwd and ppmtoxwd into pnmtoxwd. X Promoted some filters: X pcxtopbm to pcxtoppm; X ppmarith to pnmarith; X ppmconvol to pnmconvol; X ppmcscale to pnmdepth; X ppmrotate to pnmrotate; X ppmscale to pnmscale; X ppmshear to pnmshear; X ppmsmooth to pnmsmooth; X tifftopgm to tifftopnm - new version based on Sam Leffler's libtiff. X Bugfixes to pbmtoicon, ppmtops. X The Makefiles now have a "merge" option. X All flags are now case-insensitive. X Added $(MAKE) stuff to Makefile. X Changed pnmsmooth from a csh script to a sh script. X Made macro use in pbmtox10bm and pbmtoxbm more portable. X Moved compataliases to compat.csh, and added compat.ksh. X Made ppmtoilbm less Amiga-specific. X Added -headerskip and -rowskip flags to rawtopgm. X Enhanced rasttopnm to interpret 8-bit rasters with no colormap as grayscale. X Changed sscanf %g to %f - some systems can't handle %g on input. X Added -expand flag to pbmmask. X Speedup to pnmflip - don't buffer if possible. X Added color-name-to-value routine to ppm - uses X11's rgb.txt if present. X Updated Imakefile support to reflect X.V11R4. X Removed picttopbm. X Improved pnmcut argument syntax so that negative coords work like pnmpaste. X Added "magic" file, for use with the "file" program. X 40% speedup for pgmnorm from Robert Stockton (rgs@cs.cmu.edu). X Fixed long-standing bug involving colormaps on SPARCstations when X compiled with gcc -- had to do with passing structs by value. X Removed the -x flag from pnmtorast -- it's not really needed. X Fixed subtle bug in the pnm reading code that caused pnmcat to blow X it on images that differed greatly in width or height. X New version of giftoppm that handles the GIF89a standard, and doesn't X use fseek. X Fixed fitstopgm to handle three-axis images, such as the Hubble pix. X Xwdtopnm and pnmtoxwd finally handle byte-order properly. X Added -xysize flag to pnmscale. X Added conditional ANSI function prototypes to library routines. X Added -noantialias flag to pnmrotate and pnmshear. X Removed the TIPS file. No one ever sent in any new tips, so I just X moved the few I had into the relevant man pages. That's probably X where they belonged in the first place. X Added justification flags to pnmcat. X Added -map flag to ppmquant - user-specifiable colormap. Also, the X Floyd-Steinberg error diffusion finally works right. X Added -map flag to pgmtoppm. X Added DirectColor support to xwdtopnm and pnmtoxwd. X Speedup to pgmtolj from Arthur David Olson: avoid sending whitespace. X Fix to pbmtogo from Bo Thide': 2D compression now works. X XPatch 1 to the X.V11R4 / comp.sources.misc distribution of 22nov89: X X Fixed bug in pgmtops -rle. X XChanges since the alt.sources distribution of 13sep89: X X Small corrections to ppmtorast, pgmtops. X Moved pbm/tifftopbm to pgm/tifftopgm - it now handles grayscale TIFF files. X Fixed tifftopgm to handle non-native byte order. X Changes to tifftopgm to handle bogus AppleScan TIFF files, to have X better command syntax, and to use stdio. X Optimizations to xbmtopbm, pbmtoxbm, and pbmtox10bm, courtesy of X Juha Sarlin, to make them go about three times as fast. X Optimization to pgmtops and ppmtops to make them go three times as fast. X Optimization to pnmcrop. X Added PBMPLUS_BROKENPUTC defines in pbmplus.h to handle systems (such as X ULTRIX) which have broken putc() macros. X Rewrote ppmscale, pnmcat, and pgmhist to operate line-by-line, instead X of reading in the whole image. X Rewrote pnmflip to keep only one copy of the image in memory. X Added pgmtofits, courtesy of Wilson H. Bent, plus bugfixes to fitstopgm X and a patch to giftoppm to handle black&white GIF files. X Added picttopbm and rawtopgm. X Fixes to xwdtoppm and ppmtoxwd so they compile with SunOS cc as well as gcc. X Another small change to ppmtoxwd having to do with colormap size. X Changed macptopbm's -headersize flag to be -extraskip. X Changed tgatoppm to read color values as BGRA instead of ARGB; the Targa X documentation is apparently wrong about the order. X Some changes to the Makefiles, partially to work around bugs in gnumake. X Got g3topbm working, and added pbmtog3, courtesy of Paul Haeberli. X Added some pixrect work-alike code so that rasttopbm, pbmtorast, rasttoppm, X and ppmtorast can be used on non-Sun systems. This also provides a X final solution to the persistent byte- and bit-order problems on 386's. X Moved the SYSV-checking #ifdefs to *after* the include of pbm.h, which X defines SYSV. X Made all the #else's and #endif's ANSI-compliant. X Added manual pages for libpbm, libpgm, libppm, and libpnm, courtesy X of Tony Hansen. X Changed man page installation so that pages from different sections X can go in different directories. X Fixed Imakefiles. X XChanges since the expo.lcs.mit.edu FTP distribution of 06sep89: X X Added #ifdefs to pnm/libpnm3.c to allow the PBM-PNM-only configuration. X Small corrections to TIPS, pnm/Makefile, pnm/Imakefile, ppm/ppmrotate.1, X ppm/ppmshear.1, ppm/ppmtoilbm.c, pbm/xwdtopbm.c, ppm/xwdtoppm.c, X ppm/ppmtoxwd.c, ppm/ppmtoxwd.1, pbm/x11wd.h. X XChanges since the comp.sources.misc distribution of 31oct88: X X Added pbmreduce, pbmlife, pbmmask, and pbmupc. X Added gemtopbm, tifftopbm, pcxtopbm, pbmtogo, mgrtopbm, pbmtomgr, X cmuwmtopbm, pbmtocmuwm, g3topbm, and pbmtobg. X Minor bugfix to pbmtolj. X Slight restructuring of most of the programs to use vastly less memory. X Various other minor optimizations. X Fixed pbmtorast and rasttopbm to handle byte-swapped big-endian 386 boxes. X Slight changes to argument syntax of pbmcrop, pbmmake, pbmreduce. X Moved to the new PGM package: pbmtops (which now produces Conforming PS). X Moved to the new PPM package: giftopbm. X Moved to the new PNM package: pbmcrop pbmcut pbmenlarge pbminvert. X Consolidated into a single pnmflip tool: pbmfliplr pbmfliptb pbmtrnspos. X Consolidated into a single pnmcat tool: pbmcatlr pbmcattb. X Added compataliases script for upward compatability with changed tools. X Removed xxxtopbm. X Added a -headersize flag to macptopbm, to help get around annoying X problems in MacPaint file format. X Added the RAWBITS compilation-time option, to use a more compact and X much faster (but less portable) external format. X Removed the CBM format - use compress(1) and / or RAWBITS instead. X Pbmpaste (and the new pnmpaste) now accepts negative x and y coords, X which are interpreted relative to the right and bottom sides. X Changed all programs to accept a "-" file argument as meaning standard X input. X Removed pbmtox10wd, since it was never very useful (X10 doesn't have xwud). X Added Imakefiles, for X11 types to use. X XChanges since the X.V11R3 distribution of 31aug88: X X The cbm format has been revised to support run-length encoding. X Pbmtops now does run-length encoding. X XMajor changes since the X.V11R2 distribution of 28mar88: X X The pbm format now has a "magic number".
