◆ HiiDrawImageEx()

EFI_STATUS EFIAPI HiiDrawImageEx ( IN CONST EFI_HII_IMAGE_EX_PROTOCOL This,
IN EFI_HII_DRAW_FLAGS  Flags,
IN CONST EFI_IMAGE_INPUT Image,
IN OUT EFI_IMAGE_OUTPUT **  Blt,
IN UINTN  BltX,
IN UINTN  BltY 
)

Renders an image to a bitmap or to the display.

The prototype of this extension function is the same with EFI_HII_IMAGE_PROTOCOL.DrawImage(). This protocol invokes EFI_HII_IMAGE_PROTOCOL.DrawImage() implicitly.

Parameters
ThisA pointer to the EFI_HII_IMAGE_EX_PROTOCOL instance.
FlagsDescribes how the image is to be drawn.
ImagePoints to the image to be displayed.
BltIf 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.
BltXSpecifies the offset from the left and top edge of the output image of the first pixel in the image.
BltYSpecifies the offset from the left and top edge of the output image of the first pixel in the image.
Return values
EFI_SUCCESSThe image was successfully drawn.
EFI_OUT_OF_RESOURCESUnable to allocate an output buffer for Blt.
EFI_INVALID_PARAMETERThe Image or Blt was NULL.

◆ HiiDrawImageIdEx()

EFI_STATUS EFIAPI HiiDrawImageIdEx ( IN CONST EFI_HII_IMAGE_EX_PROTOCOL This,
IN EFI_HII_DRAW_FLAGS  Flags,
IN EFI_HII_HANDLE  PackageList,
IN EFI_IMAGE_ID  ImageId,
IN OUT EFI_IMAGE_OUTPUT **  Blt,
IN UINTN  BltX,
IN UINTN  BltY 
)

Renders an image to a bitmap or the screen containing the contents of the specified image.

This function is similar to EFI_HII_IMAGE_PROTOCOL.DrawImageId(). The difference is that this function will locate all EFI_HII_IMAGE_DECODER_PROTOCOL instances installed in the system if the decoder of the certain image type is not supported by the EFI_HII_IMAGE_EX_PROTOCOL. The function will attempt to decode the image to the EFI_IMAGE_INPUT using the first EFI_HII_IMAGE_DECODER_PROTOCOL instance that supports the requested image type.

Parameters
ThisA pointer to the EFI_HII_IMAGE_EX_PROTOCOL instance.
FlagsDescribes how the image is to be drawn.
PackageListThe package list in the HII database to search for the specified image.
ImageIdThe image's id, which is unique within PackageList.
BltIf 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.
BltXSpecifies the offset from the left and top edge of the output image of the first pixel in the image.
BltYSpecifies the offset from the left and top edge of the output image of the first pixel in the image.
Return values
EFI_SUCCESSThe image was successfully drawn.
EFI_OUT_OF_RESOURCESUnable to allocate an output buffer for Blt.
EFI_INVALID_PARAMETERThe Blt was NULL or ImageId was 0.
EFI_NOT_FOUNDThe image specified by ImageId is not in the database. The specified PackageList is not in the database.

◆ HiiGetImageEx()

EFI_STATUS EFIAPI HiiGetImageEx ( IN CONST EFI_HII_IMAGE_EX_PROTOCOL This,
IN EFI_HII_HANDLE  PackageList,
IN EFI_IMAGE_ID  ImageId,
OUT EFI_IMAGE_INPUT Image 
)

Return the information about the image, associated with the package list. The prototype of this extension function is the same with EFI_HII_IMAGE_PROTOCOL.GetImage().

This function is similar to EFI_HII_IMAGE_PROTOCOL.GetImage().The difference is that this function will locate all EFI_HII_IMAGE_DECODER_PROTOCOL instances installed in the system if the decoder of the certain image type is not supported by the EFI_HII_IMAGE_EX_PROTOCOL. The function will attempt to decode the image to the EFI_IMAGE_INPUT using the first EFI_HII_IMAGE_DECODER_PROTOCOL instance that supports the requested image type.

Parameters
ThisA pointer to the EFI_HII_IMAGE_EX_PROTOCOL instance.
PackageListThe package list in the HII database to search for the specified image.
ImageIdThe image's id, which is unique within PackageList.
ImagePoints to the image.
Return values
EFI_SUCCESSThe new image was returned successfully.
EFI_NOT_FOUNDThe image specified by ImageId is not available. The specified PackageList is not in the Database.
EFI_INVALID_PARAMETERImage was NULL or ImageId was 0.
EFI_OUT_OF_RESOURCESThe bitmap could not be retrieved because there was not enough memory.

◆ HiiGetImageInfo()

EFI_STATUS EFIAPI HiiGetImageInfo ( IN CONST EFI_HII_IMAGE_EX_PROTOCOL This,
IN EFI_HII_HANDLE  PackageList,
IN EFI_IMAGE_ID  ImageId,
OUT EFI_IMAGE_OUTPUT Image 
)

This function returns the image information to EFI_IMAGE_OUTPUT. Only the width and height are returned to the EFI_IMAGE_OUTPUT instead of decoding the image to the buffer. This function is used to get the geometry of the image. This function will try to locate all of the EFI_HII_IMAGE_DECODER_PROTOCOL installed on the system if the decoder of image type is not supported by the EFI_HII_IMAGE_EX_PROTOCOL.

Parameters
ThisA pointer to the EFI_HII_IMAGE_EX_PROTOCOL instance.
PackageListHandle of the package list where this image will be searched.
ImageIdThe image's id, which is unique within PackageList.
ImagePoints to the image.
Return values
EFI_SUCCESSThe new image was returned successfully.
EFI_NOT_FOUNDThe image specified by ImageId is not in the database. The specified PackageList is not in the database.
EFI_BUFFER_TOO_SMALLThe buffer specified by ImageSize is too small to hold the image.
EFI_INVALID_PARAMETERThe Image was NULL or the ImageId was 0.
EFI_OUT_OF_RESOURCESThe bitmap could not be retrieved because there was not enough memory.

◆ HiiNewImageEx()

EFI_STATUS EFIAPI HiiNewImageEx ( IN CONST EFI_HII_IMAGE_EX_PROTOCOL This,
IN EFI_HII_HANDLE  PackageList,
OUT EFI_IMAGE_ID *  ImageId,
IN CONST EFI_IMAGE_INPUT Image 
)

The prototype of this extension function is the same with EFI_HII_IMAGE_PROTOCOL.NewImage(). This protocol invokes EFI_HII_IMAGE_PROTOCOL.NewImage() implicitly.

Parameters
ThisA pointer to the EFI_HII_IMAGE_EX_PROTOCOL instance.
PackageListHandle of the package list where this image will be added.
ImageIdOn return, contains the new image id, which is unique within PackageList.
ImagePoints to the image.
Return values
EFI_SUCCESSThe new image was added successfully.
EFI_NOT_FOUNDThe PackageList could not be found.
EFI_OUT_OF_RESOURCESCould not add the image due to lack of resources.
EFI_INVALID_PARAMETERImage is NULL or ImageId is NULL.

◆ HiiSetImageEx()

EFI_STATUS EFIAPI HiiSetImageEx ( IN CONST EFI_HII_IMAGE_EX_PROTOCOL This,
IN EFI_HII_HANDLE  PackageList,
IN EFI_IMAGE_ID  ImageId,
IN CONST EFI_IMAGE_INPUT Image 
)

Change the information about the image.

Same with EFI_HII_IMAGE_PROTOCOL.SetImage(),this protocol invokes EFI_HII_IMAGE_PROTOCOL.SetImage()implicitly.

Parameters
ThisA pointer to the EFI_HII_IMAGE_EX_PROTOCOL instance.
PackageListThe package list containing the images.
ImageIdThe image's id, which is unique within PackageList.
