Routine Description: | |
Return the graphics image file named FileNameGuid into Image and return it's | |

Routine Description: | |
Convert a *.BMP graphics image to a UGA blt buffer. If a NULL UgaBlt buffer | |
is passed in a UgaBlt buffer will be allocated by this routine. If a UgaBlt | |
buffer is passed in it will be used if it is big enough. | |
Arguments: | |
BmpImage - Pointer to BMP file | |
BmpImageSize - Number of bytes in BmpImage | |
UgaBlt - Buffer containing UGA version of BmpImage. | |
UgaBltSize - Size of UgaBlt in bytes. | |
PixelHeight - Height of UgaBlt/BmpImage in pixels | |
PixelWidth - Width of UgaBlt/BmpImage in pixels | |
Returns: | |
EFI_SUCCESS - UgaBlt and UgaBltSize are returned. | |
EFI_UNSUPPORTED - BmpImage is not a valid *.BMP image | |
EFI_BUFFER_TOO_SMALL - The passed in UgaBlt buffer is not big enough. | |
