Anybody know why a 1-pixel purplish outline is showing up when using rotosprite? The image displays fine when using drawsprite.
You need to use SMOOTHSHADING FALSE prior to using ROTOSPRITE to get rid of this - it's anti-aliasing, to make the image appear smoother, getting muddled with the mask colour.
:)
or make the transparent pixels with the colour you want and add an alpha layer to the png.
