X PixMap
Color icons written as text.
XPM (X PixMap) is the usage successor to XBM. It allows for color images (and transparency) to be stored as C source code arrays. It was the standard format for icons in the Common Desktop Environment (CDE) and many Unix window managers.
An XPM file is valid C code defining a character array: `static char * icon[] = { ... }`. The data defines a color palette (mapping characters like '.' or '#' to hex colors) and then draws the image using those characters. This makes it human-readable and editable in a text editor.
Developed by Groupe Bull in 1989 to bring color support to X11 icons.
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.
