Convert G4 to VIFF

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.

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.
