Convert PFB GRAPHICS to G3

The PFB (Printer Font Binary) file extension refers to an Adobe Type 1 font used primarily on Windows PCs. Developed by Adobe Systems, PFB files contain fonts in binary format, requiring an associated PFM (Printer Font Metrics) file for proper functionality. Initially proprietary, Adobe later released the specification to third-party font manufacturers. PFB files can also be converted to image files, and AutoCAD utilizes them to create compiled font files.

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.
