NNetPBM, GRAPHICS, Suite of graphic image format manipulation & conversion pgmsH Enhanced portable bitmap toolkit. The PBMPLUS toolkit allowsH conversions between image files of different format. By means ofH using common intermediate formats, only 2 * N conversion filtersH are required to support N distinct formats, instead of the N**2H which would be required to convert directly between any one formatH and any other. The package also includes simple tools for$ manipulating portable bitmaps. D The package consists of four upwardly compatible sections: < pbm Supports monochrome bitmaps (1 bit per pixel). H pgm Supports grayscale images. Reads either PBM or PGM, formats and writes PGM format. H ppm Supports full-color images. Reads either PBM, PGM, or PPM) formats, writes PPM format. H pnm Supports content-independent manipulations on any of theH three formats listed above, as well as external formatsH having multiple types. Reads either PBM, PGM, or PPMH formats, and generally writes the same type as it readH (whenever a PNM tool makes an exception and ``promotes'' a< file to a higher format, it informs the user).P--------------------------------------------------------------------------------& N E T P B MJNetpbm is based on the widely spread Pbmplus package (release: 10 Dec 91).IOn top of that, a lot of improvements and additions have been made. AfterDthe latest release of Pbmplus, a lot of additional filters have beenKcirculating on the net. The aim of Netpbm was, to collect these and to turnHthem into a package. This work has been performed by a group of program-Kmers all over the world. If *you* have some code to add, please contact us,Iand we will incorporate it. There is a mailing list for discussions aboutLNetpbm. You post a message to the list by writing to "netpbm@fysik4.kth.se".NIf you want to be on the list, send a mail with the message "subscribe netpbm"Fto "majordomo@fysik4.kth.se". If you want to report a bug, please sendByour report to netpbm@fysik4.kth.se, and to the author of Pbmplus,jef@netcom.com.FPlease note, that this is not an official Pbmplus release. The code inGthis release is merely a collection of code from various sources aroundDthe world. Not all of the new code parts follow the high standard ofEprogramming of Pbmplus. We have tried to make the code portable to asImany systems as possible, but we haven't cleaned up all routines. We hopeFthat this release will help the many users of Pbmplus to upgrade theirDcode all in one piece, instead of having to hunt down different codeEfragments at different sites around the world. We also hope, that ourDeffort will help the author of Pbmplus, Jef Poskanzer, to make a newofficial release soon.>The file Netpbm lists all new featues and functions in netpbm.
