If alpha is zero, it checks surrounding pixels and averages color. sets new alphas to 1.0 When a mask is given, the mask will be used instead of the alpha channel, where only pixels with a mask value of 0 will be written to, and only pixels with a mask value of 1 will be used for the average. The mask will be set to one for the pixels which were written.
