- 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.
- Generic Windows or OS/2 bitmap graphic; similar to a .BMP file, but has different header information; supports 1, 4, 8, and 24 bits per pixel if the image is uncompressed and 4 and 8 bits per pixel if the image uses RLE compression; a 24-bit DIB image contains 8 bits, or 1 byte for each RGB color.
