PBMPAK - Portable Bit Map Graphics

PBMPAK is a collection of C routines for creating and reading Portable Bit Map files (PBM). Both ASCII and binary formats are supported. The library can also handle the related Portable Gray Map files (PGM) and Portable Pixel Map files (PPM) formats. Many utilities exist to translate between these formats and others such as GIF, MacPaint, X Window, and so on.

PBMPAK is a C version of a subset of the FORTRAN PBMLIB collection.

Files you may copy include:

• pbmpak.c, the library source code;
• pbmpak.h, the INCLUDE file;
• pbmpak_prb.c, the sample calling program.
• pbmpak_prb.out, the sample output file.
