About formats

JBIG (Joint Bi-level Image experts Group) is a lossless image compression standard (ITU-T T.82) published in 1993, developed by a committee of experts drawn from the same international standards bodies that created JPEG. While the extension .jbig and .jbg refer to the same underlying compression standard, .jbig is the more explicit form commonly used in software that handles the raw JBIG-compressed datastream. The compression algorithm centers on context-dependent arithmetic coding: before encoding each pixel, the encoder examines a configurable template of 10 to 16 nearby pixels (a mix of neighbors from the current and previous lines) to determine a context — one of thousands of possible local pixel configurations. Each context maintains its own adaptive probability estimate that is continually updated as encoding proceeds, allowing the coder to exploit the statistical patterns unique to each image region. This approach handles text, line art, halftoned photographs, and mixed-content pages with a single algorithm, achieving consistently better compression than the fixed Huffman tables of Group 3 or the simpler prediction model of Group 4. A later revision, JBIG2 (T.88), added pattern matching and lossy modes for even higher compression, but the original JBIG remains widely deployed. One advantage is the algorithm's adaptiveness: unlike Group 3/4 codecs that use fixed statistical models, JBIG continuously learns the characteristics of each specific image as it encodes, providing near-optimal compression across widely varying content types. The standard is embedded in many multifunction printers and document scanners for internal image handling. JBIG files are processable by ImageMagick, jbigkit, and enterprise document imaging systems.

TGA (Truevision Graphics Adapter, also known as TARGA) is a raster image format created by Truevision in 1984 for their line of display adapter cards designed for IBM PC compatibles. The format stores pixel data in a straightforward structure: an 18-byte header specifying dimensions, color depth, and image descriptor flags, optional color map data, and the pixel array in either uncompressed or RLE-compressed form. TGA supports indexed color (8-bit with palette), true color (15-bit, 16-bit, 24-bit), and true color with alpha channel (32-bit), and was one of the first PC image formats to include per-pixel alpha transparency. The format became a staple of the professional graphics industry, widely adopted by video editing suites, 3D rendering software, and game development pipelines throughout the 1990s and 2000s. One advantage is native alpha channel support — TGA was one of the earliest formats offering full 8-bit alpha transparency per pixel, making it the standard output format for 3D renderers and compositing software where layered transparency is essential. The simple, well-documented structure is another strength: TGA files are quick to parse and write, with no complex metadata or container overhead, valued in real-time applications and game engines where loading speed matters. While PNG has largely replaced TGA for general use, the format persists in game development, texture pipelines, and 3D rendering workflows where its simplicity and alpha support remain advantageous.
