Alpha (Non)Premultiplied RGB for PNG files in GapiDraw?


Alpha (Non)Premultiplied RGB for PNG files in GapiDraw?

Postby Bunkai » Nov 20, 2006 @ 7:59pm

Does anybody have experience, if it is better to use Alpha Premultiplied RGB images in PNG files, or Alpha NonPremultiplied RGB values in PNG files? I mean for GapiDraw functions of course.

The difference can affect both intensity of transparency and a speed, because AlphaPremultiplied RGB values requrie only one multiplication to compute with background.

With regards,
Rene.
