| /** | |
| 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. | |
| @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. It is the caller's | |
| responsibility to free this buffer. | |
| @param BltX Specifies the offset from the left and top edge of | |
| the output image of the first pixel in the image. | |
| @param BltY Specifies the offset from the left and top edge of | |
| the output image of the first pixel in the image. | |
| @retval EFI_SUCCESS The image was successfully drawn. | |
| @retval EFI_OUT_OF_RESOURCES Unable to allocate an output buffer for Blt. | |
| @retval EFI_INVALID_PARAMETER The Blt was NULL. | |
| @retval EFI_NOT_FOUND The image specified by ImageId is not in the database. | |
| The specified PackageList is not in the database. | |
