Images are always bi-level, 576×720 pixels in size, and use PackBits compression.

[edit] Format details
Some MacPaint files begin with a 128-byte MacBinary header; others do not. The next 512 bytes have little or no significance to most applications (they contain a version number, and usually a set of brush patterns). The pixel data starts at offset 512, or 640 if there is a MacBinary header.
