JPEG 2000 Code Stream
The raw code stream of a JPEG 2000 image.
J2C represents the raw code stream of a JPEG 2000 image, stripped of the file format wrapper (JP2). It contains the compressed image data but lacks the metadata and structural information found in a full JP2 file.
A J2C file is essentially the 'payload' of a JPEG 2000 file. It consists of a sequence of markers and compressed data segments. Because it lacks a container, it relies on the decoder to know the image parameters or infer them from the stream markers.
Defined in Part 1 of the JPEG 2000 standard (ISO/IEC 15444-1) alongside the JP2 file format.
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.
