Portable Pixel Map (ASCII) Files
Read and Write Utilities
is a C library which
reads and writes files in the
ASCII PPM (Portable Pixel Map) 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.
The computer code and data files described and made available on this web page

PPMA_IO is available in
a C version and
a C++ version and
a FORTRAN77 version and
a FORTRAN90 version and
a MATLAB version.
