When 32RGB (RGBA) pixel format is used, the A channel is not used. Alpha channel is stored in a separated plane (AlphaChannel).

To copy from A channel to Alpha channel you have to call SynchronizeRGBA with RGBAToAlpha=true.

Viceversa to copy from Alpha channel to A channel call SynchronizeRGBA with RGBAToAlpha=false.
