X BitMap
Images written as C source code.
XBM (X BitMap) is a unique image format that is actually a valid snippet of C source code. It defines an array of bytes representing a monochrome bitmap. Because it is code, it can be compiled directly into an application binary, which made it the standard for X11 icons and cursors.
An XBM file contains `#define` statements for width and height, and a static array of unsigned chars: `static unsigned char image_bits[] = { 0x00, 0xFF, ... };`. It supports only 1-bit color (black and white). Transparency works by defining a mask.
The original format for X Window System bitmaps (X10/X11). Used extensively in the 90s for the early World Wide Web (Mosaic browser) before GIF/JPEG took over.
Quite OK Image Format
Lossless compression that is incredibly fast.
QOI (Quite OK Image Format) is a modern lossless image format created by Dominic Szablewski in 2021. It was designed to be a simpler, faster alternative to PNG, prioritizing encoding and decoding speed over maximum compression ratio.
The QOI specification fits on a single page of paper. It achieves compression ratios similar to PNG but encodes 20x-50x faster and decodes 3x-4x faster. It uses a simple streaming algorithm with a running array of previously seen colors.
Released in 2021 as a reaction to the complexity of formats like PNG and the slowness of their reference implementations. It quickly gained viral popularity in the developer community.
