Please note, that this is not an official Pbmplus release. The code in this release is merely a collection of code from various sources around the world. Not all of the new code parts follow the high standard of programming of Pbmplus. We have tried to make the code portable to as many systems as possible, but we haven't cleaned up all routines. We hope that this release will help the many users of Pbmplus to upgrade their code all in one piece, instead of having to hunt down different code fragments at different sites around the world. We also hope, that our effort will help the author of Pbmplus, Jef Poskanzer, to make a new official release soon.
The file Netpbm lists all new featues and functions in netpbm.
Below this line follows the original README file from Pbmplus.
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.
Edit the top-level Makefile, find each line with the string
"CONFIGURE", and follow the directions for setting configuration
Likewise edit pbmplus.h.
If you are using gnu make, you have to edit *all* the Makefiles and remove all the imake stuff at the ends, otherwise gnu make will overwrite the Makefiles.
When you're happy that things compiled ok, make install.
If you want to use Imakefiles:
Edit Pbmplus.tmpl, find each line with the string "CONFIGURE",
and follow the directions for setting configuration options.
Likewise edit pbmplus.h.
Save the original Makefiles, in case you later want to switch back to using them.
The usual X11 sequence of xmkmf, make Makefiles, make depend, then make should work. If you have the TIFF libraries, the second step should be "make SUBDIRS='./pbm ./pgm ./ppm ./pnm' Makefiles".
When you're happy that things compiled ok, make install and make install.man.
firstname.lastname@example.orgWhen 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.
Also, if there is a new format or feature you would like to have added to the package, feel free to drop me a line. If it's a format, include whatever documentation you have, and if possible a uuencoded sample. My response time will depend on how busy I am, and how easy the job looks. If you need it right away, or it's a complicated job, you might consider paying me; lately, that's how a lot of work on the package has gotten done.
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.
