i think this should be done in edje_cc - not eet. :) (reason - edje_cc isn't speed critical. eet saves may be). :) > Hi, > Attached to the mail is a patch to set the alpha information for an image > header to 0 with alpha present but all the texels being opaque. > > The objective of this patch is to avoid the alpha blending for the images > which don't use alpha but while creating, the alpha channel has been added by > the creator.
