PBMLIB - Portable Bit Map (PBM) Graphics

PBMLIB is a C library which creates and reads Portable Bit Map (PBM) graphics files.

Both ASCII and binary PBM formats are supported. The library can also handle the related Portable Gray Map (PGM) and Portable Pixel Map (PPM) formats.

There are many graphics programs, such as XV and GIMP, that can display images in these formats, or translate them to other formats such as BMP, GIF, JPEG, MacPaint, X Window, and so on.
