Convert VIFF to G3

The Khoros Visualization Image File Format (VIFF), developed by AccuSoft Corporation, is a bitmap image format used primarily within the Khoros software environment for scientific and engineering applications. It supports various image types, including grayscale, color, and multi-spectral images, making it useful for visualizing complex datasets. Despite its powerful capabilities, VIFF is now considered somewhat obsolete due to the emergence of newer, more versatile image formats. However, it remains an important part of the history of image processing and visualization technologies.

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.
