This function renders an image to a bitmap or the screen using the specified color and options. It draws the image on an existing bitmap, allocates a new bitmap or uses the screen. The images can be clipped. If EFI_HII_DRAW_FLAG_CLIP is set, then all pixels drawn outside the bounding box specified by Width and Height are ignored. If EFI_HII_DRAW_FLAG_TRANSPARENT is set, then all 'off' pixels in the images drawn will use the pixel value from Blt. This flag cannot be used if Blt is NULL upon entry. 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.

This function renders an image as a bitmap or to the screen and can clip the image. The bitmap is either supplied by the caller or else is allocated by the function. The images can be drawn transparently or opaquely. If EFI_HII_DRAW_FLAG_CLIP is set, then all pixels drawn outside the bounding box specified by Width and Height are ignored. If EFI_HII_DRAW_FLAG_TRANSPARENT is set, then all "off" pixels in the character's glyph will use the pixel value from Blt. This flag cannot be used if Blt is NULL upon entry. 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. This function renders an image to a bitmap or the screen using the specified color and options. It draws the image on an existing bitmap, allocates a new bitmap or uses the screen. The images can be clipped. 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.

| typedef EFI_STATUS(EFIAPI * EFI_HII_GET_IMAGE) (IN CONST EFI_HII_IMAGE_PROTOCOL *This, IN EFI_HII_HANDLE PackageList, IN EFI_IMAGE_ID ImageId, OUT EFI_IMAGE_INPUT *Image) |
This function retrieves the image specified by ImageId which is associated with the specified PackageList and copies it into the buffer specified by Image. If the image specified by ImageId is not present in the specified PackageList, then EFI_NOT_FOUND is returned. If the buffer specified by ImageSize is too small to hold the image, then EFI_BUFFER_TOO_SMALL will be returned. ImageSize will be updated to the size of buffer actually required to hold the image.
