PGMA_IO
Portable Gray Map (ASCII) Files
Read and Write Utilities


PGMA_IO is a FORTRAN90 library which reads and writes files in the ASCII PGM (Portable Gray Map) format for 2D grayscale 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.
