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 RGBO format
RGBO — Raw RGB with Opacity
RGBO is a variant of the raw RGBA format used by ImageMagick where the fourth channel represents opacity rather than alpha, with inverted semantics (0 = fully transparent, like an alpha channel). It is used internally in ImageMagick for specific color operations.
Common uses
- ImageMagick internal color processing
- Opacity-based compositing workflows
- Intermediate format in image processing pipelines
- Custom color channel manipulation
