The Sun Raster file extension, also known as RAS, is a bitmap graphics file format developed by Sun Microsystems for use on their SunOS operating system. It supports black-and-white, grayscale, and color images with various pixel depths and includes simple Run-Length Encoding (RLE) compression. The format was widely used in UNIX-based systems and is supported by many imaging applications. The RAS format has largely been superseded by more modern formats but remains relevant for legacy systems and specific use cases.
The G4 file extension, standing for CCITT Group 4 Fax Image, is a specialized format used primarily for storing black-and-white facsimile (fax) images. Its origins trace back to the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as the ITU-T, which developed the Group 4 standard in the 1980s to improve fax transmission efficiency over digital networks. This format employs a high compression ratio to reduce file size while maintaining image quality, making it ideal for archiving documents and transmitting faxes in professional and business environments.
