Description
Bitmap graphic created by MacPaint for the Macintosh, one of the first painting programs for the Mac; supports only black-and-white graphics since the original Macintosh had a monochrome monitor.
Group 4 (G4) used for black and white lossless compression to maintain high-quality images, commonly used in TIFF format compression by fax machines. A picture is seen as black dots and lines on a blank page; the fewer the dots and lines are, the lesser the file size.
