IMO the ideal solution would be to have it undefined in Win32 too.

Should I draw random data into alpha? Smile

Win32 clears it for me.

Quote:

ImageDraw::alpha should be initialized to 0. Perhaps this could be done on the first call to Alpha() so there is no additional overhead for none-alpha situations?

Should not it be rather 255?
