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.
