0007790: Raspberry Pi related faster bitblt code problem with tallyIntoMap combination rule |
|
Description:
|
Reported issue was some PNG file provided as media of Scratch suddenly loading as invisible sprites.
Debugging the image showed a problem in the colorReduced method because the tallyIntoMap bitblt rule was producing incorrect values. After much staring at code we discovered a minuscule typo that had a constant in BitBltSimulation>>copyBits:Fallback: as 16r3FFF instead of 16r7FFF and thus the cmMask value used to write into the map array was wrong. |
