These are the operations (chosen from drop-down list) that have to be  
applied to the colors of the initial image (frame[i]).

1. Write on clear: frame[i]&0x00FFFFFF (erase the initial image)
2. Maximum: (frame[i]&0x00FFFFFF) | MAX(frame[i]&0xFF000000, t) (leave  
maximal colors compared to alpha map value t)
3. Minimum: (frame[i]&0x00FFFFFF) | MIN(frame[i]&0xFF000000, t) (leave  
minimal colors compared to alpha map value t)
4. Add: add alpha map
5. Subtract: subtract alpha map

The code can be seen here:

 from line 429.

Hope this helps.

Best regards,
Yuri
