Convert EPSF to G3

An EPSF, or Encapsulated PostScript File, is a graphics file format used primarily in the publishing and printing industries for embedding high-resolution images within other PostScript documents. Introduced by Adobe Systems in the late 1980s, EPSF files enable seamless integration of complex visual elements, maintaining quality and device independence. They encapsulate both vector and raster graphics, allowing detailed illustrations and photographs to be embedded without loss of resolution, facilitating professional-quality output across various platforms and devices.

The G3 file extension refers to the CCITT Group 3 Fax Image, a standardized format developed by the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as ITU-T. This format was created to efficiently compress black-and-white fax documents for transmission over telephone lines. It employs a method called Modified Huffman Coding for data compression, enabling reduced transmission time and bandwidth usage. G3 was widely adopted in the 1980s and 1990s as the primary standard for fax transmissions, ensuring compatibility across different fax machines and systems.
