About the MAP format

Common uses

- Palette extraction and analysis
- Indexed color image workflows
- Batch color quantization pipelines
About the G3 format
G3 — CCITT Group 3 FAX
G3 is a monochrome image format defined by the CCITT (ITU-T) standard for Group 3 fax transmission. It encodes pages as compressed bitstreams using Modified Huffman (MH) or Modified READ (MR) compression, designed to minimize transmission time over telephone lines.
Common uses
