- Description
- The PNM (Portable Any Map Image) file format is a subset of the broader Netpbm format, designed for storing various types of digital images. It acts as an umbrella term for three specific types of grayscale, color, and black-and-white images, represented by PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap) formats respectively. PNM files are known for their simplicity and ease of conversion to other image formats.
- Image saved in the native graphics format used by Silicon Graphics workstations; can store 8 to 32 bits per pixel; also supports Run-length encoding (RLE) compression for reducing the image file size.
