Description
This PR adds a new abstract
AlphaAwareImageEncodertype which is used to normalize transparent color handling during encoding. Prior to this normalization both PNG and WEBP encoders had separate enum properties that used the same values and behavior. Now any encoder which belongs to an image format that is capable of encoding alpha data shares the same options and functionality.In addition:
ImageFrame.Boundswas normalized to a readonly property to matchImage
