This is my second (and hopefully better) attempt at porting the PBMPlus package to MS-DOS. I used D.J. Delorie's port of the GNU GCC compiler to DOS to compile the package. The GCC compiler generates 386 specific, protected mode code. Used with DJ's DOS extender (built into the executables distributed with this package) allows for some pretty powerful programs. The current DOS extender (or rather, the one I'm currently using, there may be newer version with more compatibilities), is not compatible with much of anything besides vanilla DOS. No EMM386.SYS, QEMM.SYS, Desqview, Windows, etc. Source for the DOS extender is available with the GCC package. You can obtain the package from the internet at grape.ecs.clarkson.edu:pub/msdos/djgcc/* or (315)268-6667:pub/msdos/djgcc/*. Feel free to add VCPI or DPMI support. Improvements: o RAWBITS binary formats for p?m files. This allows MUCH faster executions times, as well as smaller temporary files. This same fix also allows for the familiar unix-style pipings, such as: tgatoppm dkbtest.tga | ppmquant 256 | ppmtogif > dkbtest.gif This makes for this source code to be much closer to the PBMPLUS package as distributed by Jef Poskanzer. The only minor problem this causes is when you want to use an ASCII only p?m file, you have to change all the LF/CR sequences into LF only (that is, run it through a DOS-to-UNIX text file filter). o MERGE option for binaries. This essentially creates one big exectuable file rather than a bunch of smaller ones. On unix systems, you can use this option, as well as file links (pointers to a file, rather than an actuall file) to point to this one exectuable. It can save a tremendous amount of space. How the program works depends on what the name is of program when you execute it. On a DOS machine, you have to copy or rename the executable to get the appropriate function (remember, how the program works depends on how it's named). If you want the whole package, the MERGE option will take up more room on a DOS machine, but it makes for a smaller package to send around the net, and smaller and putting all the unused files into an archive if you only want part of the package. The entire PBMPLUS package, when compiled into separate binaries, takes up just over 6 Megs of diskspace. The equivalent package compiled using the merge option takes up about 300k. The executables I plan to distribute are the merged binaries. The binaries can be renamed/copied to the following to get the desired results: pbmmerge.exe to brushtop.exe cmuwmtop.exe g3topbm.exe icontopb.exe gemtopbm.exe macptopb.exe mgrtopbm.exe pbmlife.exe pbmmake.exe pbmmask.exe pbmpaste.exe pbmreduc.exe pbmtext.exe pbmto10x.exe pbmtoasc.exe pbmtobbn.exe pbmtocmu.exe pbmtoeps.exe pbmtog3.exe pbmtogem.exe pbmtogo.exe pbmtoico.exe pbmtolj.exe pbmtomac.exe pbmtomgr.exe pbmtopi3.exe pbmtoplo.exe pbmtoptx.exe pbmtox10.exe pbmtoxbm.exe pbmtoybm.exe pbmtozin.exe pbmupc.exe pi3topbm.exe xbmtopbm.exe ybmtopbm.exe pgmmerge.exe to fitstopg.exe fstopgm.exe hipstopg.exe lispmtop.exe pgmbentl.exe pgmenhan.exe pgmhist.exe pgmnorm.exe pgmoil.exe pgmramp.exe pgmtopbm.exe pgmtofit.exe pgmtofs.exe pgmtolis.exe pgmtops.exe psidtopg.exe rawtopgm.exe pgmedge.exe ppmmerge.exe to giftoppm.exe gouldtop.exe ilbmtopp.exe imgtoppm.exe mtvtoppm.exe pcxtoppm.exe pgmtoppm.exe pi1toppm.exe picttopp.exe ppmhist.exe ppmmake.exe ppmquant.exe ppmrelie.exe ppmtogif.exe ppmtoicr.exe ppmtoilb.exe ppmtopcx.exe ppmtopgm.exe ppmtopi1.exe ppmtopic.exe ppmtops.exe ppmtopuz.exe ppmtorgb.exe ppmtouil.exe ppmtoxpm.exe qrttoppm.exe rawtoppm.exe rgb3topp.exe spctoppm.exe sputoppm.exe tgatoppm.exe ximtoppm.exe xpmtoppm.exe ppmpat.exe pnmmerge.exe to pnmarith.exe pnmcat.exe pnmconvo.exe pnmcrop.exe pnmcut.exe pnmdepth.exe pnmenlar.exe pnmfile.exe pnmflip.exe pnminver.exe pnmnoraw.exe pnmpaste.exe pnmscale.exe pnmtile.exe pnmtoras.exe pnmtoxwd.exe rasttopn.exe xwdtopnm.exe pnmgamma.exe pnmrotat.exe pnmshear.exe Diffs will be also be distributed for those who want to compile the package on their own (The DOS port of GCC is necessary for this). Aside from the introduction of the fmod() function to all the main programs, there are some minor adjustments made to the makefiles to make them work with the DOS port of GNU-Make. Two batch files, all.bat and merge.bat are provided to run the make process. ALL.BAT will complete make all of the stand alone executables (.exe's files). MERGE.BAT will only make the 32-bit code in a file called p?mmerge. which will have to be manually appended to the appropriate STUB.EXE or GO32.EXE which comes with the DOS port of GCC. These two batch files are found in the root directory. In each of the p?m directory, there are two more batch files called delp?m.bat and exep?m.bat. DELP?M.BAT just goes through and cleans up all the 32-bit code generated by the compiler and should be used after you make all of the .exe files. EXEP?M.BAT goes through and prepends with the go32.exe or stub.exe DOS extenders to each of the 32-bit code segments. Edit that batch file to have the appropriate environment variable point to whichever you want. I used the BETA TEST distribution of 05feb91 to generate this version of pbmplus (I no longer have net access, so at this time I'm not sure if this is the latest version). NOTICE: I made one minor modification to ppmtogif.c. It now sorts the palette based on it's luminisity. This makes the darkest color the background color, which is a personal preference.
