Is it able to flip and rotate TIFF-Files with a libtiff-function?

if YES --> Which function is it?!
if NO --> Has anyone written a function to rotate or to flip an image? Is

Do you need to actually rotate an image or you just want to alter the 'Orientation' tag without changing data? In former case read here:

In latter case you should read the image directory, change the tag value and write it back using the TIFFRewriteDirectory() function.
