1178 This function renders an image to a bitmap or the screen using the specified

1181
1182 @param This A pointer to the EFI_HII_IMAGE_PROTOCOL instance.
1183 @param Flags Describes how the image is to be drawn.
1184 @param Image Points to the image to be displayed.
1185 @param Blt If this points to a non-NULL on entry, this points
1186 to the image, which is Width pixels wide and
1187 Height pixels high. The image will be drawn onto
1188 this image and EFI_HII_DRAW_FLAG_CLIP is implied.

1190 will be allocated to hold the generated image and
1191 the pointer updated on exit. It is the caller's
1192 responsibility to free this buffer.
1193 @param BltX Specifies the offset from the left and top edge of
1194 the output image of the first pixel in the image.
1195 @param BltY Specifies the offset from the left and top edge of
1196 the output image of the first pixel in the image.
