MegaPaint BLD is the main native raster graphics format of MegaPaint, a graphics editor developed by TommySoftware. There were editions of MegaPaint for Atari ST, MS-DOS, and Windows. Some were released as shareware. The best information about MegaPaint might be in German.
In addition to raster graphics, MegaPaint apparently has some sort of support for vector graphics.
