This function optionally updates an image and/or its display coordinates and optionally displays
|
|
the image.
|
|
If the function displays the image OR the function wants to prevent the kernel from
|
|
displaying the image, this function should return EFI_SUCCESS.
|
|
If the function does not display the image, but updates the image data or image type, this
|
|
function should return EFI_MEDIA_CHANGED. The caller will free the original image data and the
|
|
returned image data.
|
|
If the function does not display the image, but updates the image coordinates, this function
|
|
should return EFI_MEDIA_CHANGED. The caller will free the original image data.
|
|
If the function does not wish to make any changes to the image data or image coordinates OR the
|
|
function is not implemented, it should return EFI_UNSUPPORTED.
|

|
|
@param[in out] Id The logo identifier describes how the kernel plans to use the logo.
|
|
On entry, points to an unsigned integer that specifies the logo identifier.

|
@param[in out] PosX On entry, points to an integer that specifies the horizontal offset relative to the origin specified by OriginX.
|
|
On exit, points to an updated integer.
|
|
@param[in out] PosY Points to an integer that specifies the vertical offset relative to the origin specified by OriginY.
|
|
On exit, points to an updated integer.
|
|
@param[in out] OriginX On entry, points to an enumerated value that specifies
|
|
the horizontal origin.
|
|
On exit, points to an updated enumerated value.
|
|
0 = Left edge is 0.
|
|
1 = Left edge is the width of the screen, less the width of the
|
|
logo.
|
|
2 = Left edge is the width of the screen, less the width of the
|
|
logo, divided by 2.
|
|
@param[in out] OriginY On entry, points to an enumerated value that specifies the
|
|
vertical origin.
|
|
On exit, points to an updated enumerated value.
|

2 = Top edge is the height of the screen, less the height of the logo, divided by 2.
|
|
@param[in out] ImageType On entry, points to an enumerated value that specifies the format of the image data pointed to by ImageData.
|
|
On exit, points to an updated enumerated value.
|
|
0 = BMP
|
|
1 = JPEG
|
|
2 = GIF
|
|
3 = PNG

|
@param[in out] ImageData On entry, points to a pointer to a buffer that contains the raw image data.
|
|
On exit, points to a pointer to an updated buffer that contains the raw image data.
|
|
@param[in out] ImageSize On entry, points to an unsigned integer that specifies the size of ImageData, in bytes.
|

On exit, points to an updated unsigned integer.
|
|
|
|
@retval EFI_UNSUPPORTED The function is not implemented or the image data and attributes have not been updated.
|
|
The kernel should display the image at the specified coordinates and free the image specified by
|
|
ImageData.
|
|
@retval EFI_SUCCESS Image has been successfully handled by this function.
|
|
The kernel should free the image specified by ImageData and should not display the image.
|
|
@retval EFI_MEDIA_CHANGED Image data or attributes have been updated by this function.
|
|
The kernel should display the image at the specified coordinates and free the image passed in to the function,
|
|
as well as the image specified by ImageData.
|
|
@retval Others Based on OEM design.
