- image can have pixels with different transparences (alpha)
- it uses colors (R,G,B,A) instead of (R,G,B) ( (R,G,B) == (R,G,B,255) )
- it needs
surface.convert_alpha() surface.fill([0,0,0,0])gives transparent background (important is only alpha=0)- it can't use
set_alpha()to change transparency
important is only alpha=0
- it uses
set_alpha()to change transparency - it uses colors (R,G,B) - (R,G,B,A) makes no difference (it is treated as (R,G,B,255))
surface.set_colorkey([0,0,0])gives transparent background
(it can be any color but [0,0,0] is default background color for new surface)
