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.

PALM is a bitmap image format used by the Palm OS operating system, introduced in 1996 with the original Palm Pilot 1000. Palm bitmap files store raster images in formats optimized for the extremely constrained hardware of early Palm handheld devices — the original models featured a 160x160 pixel monochrome (2-shade) display, 128 KB of RAM, and a 16 MHz Motorola 68328 processor. The format evolved through several versions as Palm hardware improved: PalmOS 1.0 supported 1-bit monochrome, later versions added 2-bit (4 shade grayscale), 4-bit (16 shade), 8-bit (256 color), and eventually 16-bit (65536 color) direct color modes. Palm bitmaps use a simple header specifying width, height, row bytes, flags, and bit depth, followed by the pixel data which may use optional Scanline compression (a PackBits-like run-length encoding) or dense packing. The format also supports bitmap families — multiple versions of the same image at different bit depths bundled together, allowing the OS to select the best version for the current device's display capabilities. One advantage is the format's documentation of early mobile computing: Palm OS was the dominant handheld platform of the late 1990s and early 2000s, and Palm bitmap files from applications, games, and content of that era represent important artifacts of mobile computing history. The multi-depth bitmap family feature provides another notable design strength — a single resource could serve devices ranging from monochrome Palm Pilots to the 16-bit color Sony CLIE and Palm Tungsten. PALM bitmaps are supported by ImageMagick, pilot-link utilities, and Palm emulator tools.
