About formats

MTV is a simple raster image format created by Mark T. VandeWettering for the MTV Ray Tracer, a ray tracing program released in 1988 as one of the early publicly available ray tracers distributed through Usenet. The format stores 24-bit RGB images with a minimal text header followed by raw pixel data. The header consists of a single line containing the image width and height as ASCII integers, followed immediately by the pixel data where each pixel occupies three bytes (red, green, blue) arranged in row-major order from top-left to bottom-right. The MTV Ray Tracer itself was significant in the history of computer graphics — distributed freely via the comp.graphics Usenet newsgroup, it introduced many programmers and students to the principles of ray tracing: ray-object intersection, reflection, refraction, shadows, and recursive shading. The MTV format was the program's native output, and its simplicity made it easy for users to write custom viewers and converters on whatever platform they had access to — a practical necessity in the fragmented Unix workstation landscape of the late 1980s. One advantage is extreme implementation simplicity: the format can be read in a handful of lines of code in any programming language, with no libraries, no compression algorithms, and no metadata parsing required — just read two integers and then read width x height x 3 bytes of pixel data. The format's historical significance in the computer graphics community provides another dimension — MTV files from early ray tracing experiments represent primary artifacts from the era when ray tracing transitioned from academic research to accessible software. MTV files are supported by ImageMagick and various legacy graphics tools.
Initial release: 1988
G4 is a monochrome image format based on the ITU-T Group 4 facsimile coding standard (Recommendation T.6), ratified by the CCITT in 1984 as an improvement over Group 3 for use on error-free digital networks like ISDN rather than analog telephone lines. G4 files contain 1-bit image data compressed using exclusively two-dimensional Modified Modified READ (MMR) coding, where each scanline is encoded as a set of differences (changing elements) relative to the line above it. By eliminating the one-dimensional coding fallback and the end-of-line synchronization markers required by Group 3, G4 achieves 20-50% better compression ratios on typical document pages while producing a simpler, more regular bitstream. The format is most commonly encountered as a compression method within TIFF files (TIFF compression tag 4), where it became the standard archival format for scanned documents in enterprise document management, government records, and legal imaging systems. G4 compression is specified at 200, 300, or 400 dpi depending on the scanning application, with 300 dpi being the most common for archival-quality document imaging. One advantage is exceptional compression efficiency for document content: G4's two-dimensional prediction exploits the strong vertical correlation in text and line art pages, typically compressing a 300 dpi letter-size page to 30-50 KB — roughly half the size of equivalent Group 3 encoding. The format's entrenchment in document management infrastructure is another strength — G4 TIFF is the mandated format for many government digital records systems, court filing systems, and corporate archives, supported by every enterprise imaging platform.
