## Detailed Description

The Fl_PNM_Image class supports loading, caching, and drawing of Portable Anymap (PNM, PBM, PGM, PPM) image files.

The class loads bitmap, grayscale, and full-color images in both ASCII and binary formats.

## Constructor & Destructor Documentation

Fl_PNM_Image::Fl_PNM_Image | ( | const char * | name | ) |
