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 PackBits 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.

Identifiers

  • MacBinary type: PNTG

Sample files

Specifications

Software

  • Netpbm (macptopbm). Use the -extraskip 128 option if the file has a MacBinary header.
