About the MAC format
MAC — MacPaint Image
MAC is the native bitmap format of MacPaint, Apple's original paint application bundled with the first Macintosh in 1984. MacPaint files are monochrome (black and white) 576×720 pixel images that represent one of the earliest consumer bitmap graphics formats in computing history.
Common uses
- Recovering early Macintosh MacPaint artwork
- Historical computing and art preservation
- Converting classic Mac graphics to modern formats
- Computing history archive projects
About the PGM format
PGM — Portable Graymap
PGM is the grayscale member of the Netpbm family. It stores each pixel as a gray value (8 or 16 bits), making it ideal for grayscale image processing, scientific imaging, and intermediate conversion steps. Like PBM, it can be stored as ASCII or binary.
Common uses
- Grayscale image processing and analysis
- Scientific and medical image workflows
- Machine learning image preprocessing
- Intermediate format in Netpbm conversions
