Convert VDA to G3

The VDA file extension, associated with Truevision Advanced Raster Graphics Adapter (TARGA), is a raster graphics file format developed by Truevision Inc. It was designed for high-color and true-color display on IBM-compatible PCs, supporting resolutions matching NTSC and PAL video formats. VDA files are used for digital photos, textures, and video editing, offering various color depths (8 to 32 bits) and alpha channel transparency. The format includes both lossless and lossy compression options, ensuring high-quality image preservation.

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.
