In Imagemagick, there is a -rotate option which can be provided with -annotate to rotate text relative to the image. I do not see how to do this in wand. I am thinking of making a private version of wand with this option added, but the coding is a bit advanced for me. Is there a way to support it?
The hack would be use python to create "convert" command lines which are sent to a shell for execution, but obviously I'd rather use a python binding.
I used to do this sort of thing with PerlMagick.
I tried setting draw.rotate or draw.rotation variables, but inspection of the source code makes it clear these are not supported.
