JPEG 2000 File Format
The advanced successor to JPEG that never quite took off on the web.
JPEG 2000 (JP2) is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard with a newly designed, wavelet-based method.
JP2 uses discrete wavelet transform (DWT) technology, which allows for higher compression ratios without the 'blocky' artifacts seen in standard JPEGs. It supports both lossy and lossless compression in a single architecture and allows for progressive decoding (quality or resolution).
Released in 2000 as a modern upgrade to JPEG. Despite its technical superiority, it failed to gain widespread web adoption due to patent concerns, complexity, and the 'good enough' nature of standard JPEG.
Palm Pixmap
The graphics format for Palm Pilot PDAs.
The Palm Pixmap format is the native bitmap resource used by Palm OS devices (like the Palm Pilot, Tungsten, and Treo). It was designed for the constraints of early handhelds: low memory, low CPU power, and limited screen depth (initially 1-bit, then 4-bit grayscale, then 8/16-bit color).
Palm images are usually stored inside a pdb (Palm Database) container file. The pixel data itself supports multiple compression types, primarily PackBits (RLE) and ScanLine. It handles transparency via a designated transparent index color. The format is tightly coupled with the Palm OS resource manager structure.
Debuted with the original Palm Pilot in 1996. As screen technology evolved, the format was extended to support color and high density (double density) screens on devices like the Sony Clie and Palm Tungsten.
