Routine Description:
This function adds the image Image to the group of images owned by PackageList, and returns
a new image identifier (ImageId).
Arguments:
This - A pointer to the EFI_HII_IMAGE_PROTOCOL instance.
PackageList - Handle of the package list where this image will be added.
ImageId - On return, contains the new image id, which is unique within PackageList.
Image - Points to the image.
Returns:
EFI_SUCCESS - The new image was added successfully.
EFI_NOT_FOUND - The specified PackageList could not be found in database.
EFI_OUT_OF_RESOURCES - Could not add the image due to lack of resources.
EFI_INVALID_PARAMETER - Image is NULL or ImageId is NULL.

Routine Description:
This function retrieves the image specified by ImageId which is associated with

Arguments:
This - A pointer to the EFI_HII_IMAGE_PROTOCOL instance.
PackageList - Handle of the package list where this image will be searched.
ImageId - The image¡¯s id,, which is unique within PackageList.
Image - Points to the image.
ImageSize - On entry, points to the size of the buffer pointed to by Image, in bytes. On return,
points to the length of the image, in bytes.
Returns:
EFI_SUCCESS - The new image was returned successfully.
EFI_NOT_FOUND - The image specified by ImageId is not available.
EFI_BUFFER_TOO_SMALL - The buffer specified by ImageSize is too small to hold the image.
EFI_INVALID_PARAMETER - The Image or ImageSize was NULL.

Routine Description:
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.
Arguments:
This - A pointer to the EFI_HII_IMAGE_PROTOCOL instance.
Flags - Describes how the image is to be drawn.
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
output image of the first pixel in the image.
Returns:
EFI_SUCCESS - The image was successfully drawn.
EFI_OUT_OF_RESOURCES - Unable to allocate an output buffer for Blt.
EFI_INVALID_PARAMETER - The Image or Blt was NULL.
EFI_INVALID_PARAMETER - Any combination of Flags is invalid.
