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.

Other MegaPaint formats include:
- .PAT - MegaPaint pattern
- .VEK - MegaPaint vector format
- .LIB - MegaPaint symbols library
- .VLB - MegaPaint vector symbols library
- .FNT - MegaPaint font
[edit] Format details
BLD format:
| Offset | Type | Details |
|---|---|---|
| 0 | signed int16 BE | Code for the image width and compression scheme. Actual width is 1 + the absolute value of this field. If negative, image is compressed. |
| 2 | signed(?) int16 BE | Code for the image height. Actual height is 1 + the value of this field. |
| 4 | bytes | The pixel data. After decompression if necessary (see below), the format is 1 bit/pixel, white-is-zero. Rows are padded to the next byte boundary. |
[edit] Decompression algorithm
Read the next byte, follow the instructions below, repeat.
| Code byte (N) | Instructions |
|---|---|
| N=0 or N=255 | Read the next byte (C). Emit C+1 bytes of value N. |
| Any other | Emit 1 byte of value N. |
