The Silicon Graphics Image (SGI) file format, developed by Silicon Graphics Inc. in 1995, is a raster graphics format designed for high-quality color images. It supports 8 to 32 bits per pixel, three primary color channels, and an optional alpha channel for transparency. The format employs run-length encoding (RLE) compression to minimize file sizes. Initially utilized on Silicon Graphics workstations, the SGI format remains compatible with modern image viewers and editors.
The PNM (Portable Anymap) file extension, developed by Jef Poskanzer in the 1980s, stands for Portable Any Map. It is an uncompressed raster graphics format designed for portable image storage and exchange, encompassing three sub-formats: PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM files store image data in plain text or binary format, ensuring easy usage across different platforms and applications. This format is widely supported by various image editing software and is valued for its simplicity and lossless compression.
