TRawImageDescription.MaskBitsPerPixel : Byte; |
A pixel Mask (currently) has a logical depth of 1 bit per pixel, but a pixel can occupy an entire byte. As opposed to the Alpha (transparency) channel, a Mask is stored in its own array. A Mask value of 1 means that the pixel is masked (transparent); a value of 0 means the pixel value is shown (opaque).
