If EFI_HII_DRAW_FLAG_CLIP is set, then + all pixels drawn outside the bounding box specified by Width and + Height are ignored. The EFI_HII_DRAW_FLAG_TRANSPARENT flag + determines whether the image will be drawn transparent or + opaque. If EFI_HII_DRAW_FLAG_FORCE_TRANS is set, then the image + will be drawn so that all 'off' pixels in the image will + be drawn using the pixel value from Blt and all other pixels + will be copied. If EFI_HII_DRAW_FLAG_FORCE_OPAQUE is set, then + the image's pixels will be copied directly to the + destination. If EFI_HII_DRAW_FLAG_DEFAULT is set, then the image + will be drawn transparently or opaque, depending on the + image's transparency setting (see EFI_IMAGE_TRANSPARENT). + Images cannot be drawn transparently if Blt is NULL. If + EFI_HII_DIRECT_TO_SCREEN is set, then the image will be written + directly to the output device specified by Screen. Otherwise the + image will be rendered to the bitmap specified by Bitmap. + + @param This A pointer to the EFI_HII_IMAGE_PROTOCOL instance. + + @param Flags Describes how the image is to be drawn. + + @param PackageList The package list in the HII database to + search for the specified image. + + @param ImageId The image's id, which is unique within PackageList. + + @param Blt If this points to a non-NULL on entry, this points + to the image, which is Width pixels wide and + Height pixels high. The image will be drawn onto + this image and EFI_HII_DRAW_FLAG_CLIP is implied. + If this points to a NULL on entry, then a buffer + will be allocated to hold the generated image and + the pointer updated on exit.
