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.
- Parameters
-
| This | A pointer to the EFI_HII_IMAGE_PROTOCOL instance. |
| PackageList | The package list in the HII database to search for the specified image. |
| ImageId | The image's id, which is unique within PackageList. |
| Image | Points to the new image. |
- Return values
-
| EFI_SUCCESS | The image was returned successfully. |
| EFI_NOT_FOUND | The image specified by ImageId is not available. Or The specified PackageList is not in the database. |
| EFI_INVALID_PARAMETER | The Image or Langugae was NULL. |
| EFI_OUT_OF_RESOURCES | The bitmap could not be retrieved because there was not enough memory. |

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.
- Parameters
-
| This | A pointer to the EFI_HII_IMAGE_PROTOCOL instance. |
| Flags | Describes how the image is to be drawn. EFI_HII_DRAW_FLAGS is defined in Related Definitions, below. |
| Image | Points to the image to be displayed. |
| 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. |
| BltX,BltY | Specifies the offset from the left and top edge of the image of the first pixel in the image. |
- Return values
-
| EFI_SUCCESS | The image was successfully updated. |
| EFI_OUT_OF_RESOURCES | Unable to allocate an output buffer for RowInfoArray or Blt. |
| EFI_INVALID_PARAMETER | The Image or Blt or Height or Width was NULL. |
Definition at line 247 of file HiiImage.h.
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.
- Parameters
-
| This | A pointer to the EFI_HII_IMAGE_PROTOCOL instance. |
| Flags | Describes how the image is to be drawn. |
| PackageList | The package list in the HII database to search for the specified image. |
| ImageId | The image's id, which is unique within PackageList. |
| 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. |
| BltX,BltY | Specifies the offset from the left and top edge of the output image of the first pixel in the image. |
- Return values
-
| EFI_SUCCESS | The image was successfully updated. |
| EFI_OUT_OF_RESOURCES | Unable to allocate an output buffer for RowInfoArray or Blt. |
| EFI_NOT_FOUND | The image specified by ImageId is not in the database. Or The specified PackageList is not in the database. |
| EFI_INVALID_PARAMETER | The Blt was NULL. |
