DelmPaint *.DEL, *.DPH<br />
<br />
Delmpaint is a 256 color painting package. It works in 320x200 and 320x240 but<br />
there is no difference in the file type. From a .DEL file you can not tel whether<br />
it is a 320x200 or a 320x240 file. The same is true for a *.DPH file, which is <br />
either a 640x400 or a 640x480 file. The bigger format is always assumed.<br />
<br />
*.DEL format:<br />
The *.DEL format contains 3 compressed blocks which are decompressed 32000 bytes.<br />
Those three blocks joined together are the depacked file.<br />
Paked:<br />
1 long length of 1st packed block<br />
1 long length of 2nd packed block<br />
??? bytes 1st packed block, depacked 32000 bytes<br />
??? bytes 2nd packed block, depacked 32000 bytes<br />
??? bytes 3rd packed block, depacked 32000 bytes<br />
The blocks are packed with the same algorithm as used in Crackart<br />
<br />
Depacked:<br />
256 longs Palette 256 colors, in Falcon format, R, G, 0, B<br />
38400 words Picture data, 8 interleaved bitplanes<br />
<br />
*.DPH format:<br />
The *.DPH format contains 11 compressed blocks which are decompressed 32000 bytes.<br />
Those three blocks joined together are the depacked file.<br />
Paked:<br />
10 long length of 11st to 10th packed block<br />
<br />
??? bytes 1st packed block, depacked 32000 bytes<br />
??? bytes 2nd packed block, depacked 32000 bytes<br />
....<br />
??? bytes 1th packed block, depacked 32000 bytes<br />
The blocks are packed with the same algorithm as used in Crackart<br />
<br />
Depacked:<br />
256 longs Palette 256 colors, in Falcon format, R, G, 0, B<br />
38400 words Picture 1 320x240 data, 8 interleaved bitplanes<br />
38400 words Picture 2 320x240 data, 8 interleaved bitplanes<br />
38400 words Picture 3 320x240 data, 8 interleaved bitplanes<br />
38400 words Picture 4 320x240 data, 8 interleaved bitplanes<br />
Finally you have to join the pictures into one huge 640x480 picture.<br />
Take 320 bytes from picture 1, then 320 from 2, repeat 240 times, do<br />
the same for picture 3 and 4.<br />
