During application development, we came across a place where DrawImage() does
not fully implement the specification. Specifically, if the image is to be
drawn transparently directly to the screen, it simply returns
EFI_INVALID_PARAMETER (see code snippet from Image.c in HiiDatabaseDxe). I am
surprised that the SCT doesn't catch this issue.
Any plans to implement? Thanks,
Tim
//
// Image cannot be drawn transparently if Blt points to NULL on entry.
// Currently output to Screen transparently is not supported, either.
//
if (Transparent) {
if (*Blt == NULL) {
return EFI_INVALID_PARAMETER;
} else if ((Flags & EFI_HII_DIRECT_TO_SCREEN) == EFI_HII_DIRECT_TO_SCREEN) {
return EFI_INVALID_PARAMETER;
}
}
