MacPaint

Overview
MacPaint is the native image format of the MacPaint paint program for Apple Macintosh.

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

Format
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. The pixel data starts at offset 512, or 640 if there is a MacBinary header.
