PPMA_IO
Portable Pixel Map (ASCII) Files
Read and Write Utilities

PPMA_IO is a C++ library which reads and writes files in the ASCII PPMA format for 2D color graphics information.

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