I found out about libtiff while trying to create a low resolution(72dpi) tiff image from a high resolution tiff image and copy the clippath tag along.

If you are scaling the image, you will also need to scale the clippath - NOT just copy it since the values are all wrong now...

There is code in ImageMagick/GraphicsMagick for reading/parsing the clippath to make it into a useable format (SVG), though we don't currently write the clippath back out...
