- Description
- AT&T Group 4 is a file format used for compressing high-resolution data. It is most commonly used for storing images such as TIFFs, JPEGs, and GIFs. The format is lossless, meaning that no data is lost during compression.
- A BMP file is an uncompressed raster image comprised of a rectangular grid of pixels. It contains a file header (bitmap identifier, file size, width, height, color options, and bitmap data starting point) and bitmap pixels, each with a different color.
