Is there any way by which we can force the libtiff library to return the data always in TOP-LEFT orientation, no matter what is the actual orientation of image data?

Or, is there any other round-about way by which we can achieve that?

There is a special function TIFFGetRGBAImageOriented() for that purpose. But it always reads the whole image into the memory and always converts pixels to RGBA representation. If you are using TIFFReadStrip/Tile functions you should take care of orientation yourself.
