to put the image in the given image buffer. That allows the caller to put an

image overlap on the original image. The transparency is handled by the image

decoder because the transparency capability depends on the image format. Callers

can set Transparent to FALSE to force disabling the transparency process on the

image. Forcing Transparent to FALSE may also improve the performance of the image

decoding because the image decoder can skip the transparency processing. If **Bitmap

free the memory for EFI_IMAGE_OUTPUT. Image decoder doesn?t have to handle the
