I traced this problem to a one-line bug in the GIF loading code. The code is supposed to initialize a transparency flag to -1 when no transparency is used, or else the palette index of the transparency color. The sample image I was using indicates that the transparency index is 255. Due to an unintended sign extension, the transparency index (held in a Byte array of basic type "signed char") is sign-extended to the variable "transparency" of basic type "signed int". This causes the flag to be assigned the value -1, which happens to be the same value used as a no-transparency indicator. So transparency was ....^^^^^^^^^^^^
Heh, 3 times "the transparency" in exactly the same line position, 4 times "transparency" in exactly the same position - what did you smoke?? ;-) (or worse, what did *I* smoke to recognize this?? :-) OK, I promise I'll stop that useless fun email here. Anyway, thanks for all those nice patches, Andreas Mohr
