MPNT to SGI Conversion: FAQ

What are MPNT files?

MPNT is an image format associated with MacPaint, an incipient version of Paintbrush. MacPaint was released in the 1980s as part of the basic software pack included on MacIntosh computers and it represented a basic drawing program meant to help users create and edit images quickly. The last stable release of MacPaint dates from 1988, so MPNT files are now considered archaic and obsolete. As its successor, Paintbrush offers users a wider variety of image editing options and can be used on both Microsoft and Apple platforms.

What are SGI files?

SGI (Silicon Graphics Image) is a raster image format associated with Silicon Graphics workstations. It is a bitmap file that can store black-and-white, gray-scale and color images, and may also contain color maps and alpha channels. SGI files are sometimes referred to as RGBs and can either use no image compression or RLE compression. Alternative extensions for the SGI format are BW, RGB and RGBA.
