MacPaint

MacPaint was a bitmap -based image editor that has already been delivered in 1984 on the first Macintosh by Apple along with MacWrite and was in several enhanced versions to 2004 on the market. MacPaint was groundbreaking for many other similar programs that work like pixels Paint and Photoshop, which was available in 1990 on the Macintosh IIfx first time.

Thanks graphical user interface created with MacPaint images could even then be easily inserted into MacWrite documents and also printed. Since the first Macintosh only had a black and white screen, you could edit with MacPaint only black and white images ( resolution of only 576 × 720 pixels). But this was not a limitation, because the then connectable ImageWriter could default, only black and white images of size 203 × 204 mm with 72 DPI Print.

MacPaint image files can be converted using the command line tool macptopbm (part of the Netpbm project) in PBM files, this format can be processed further with today's programs.
