Using part of image has target.

[oivvio]

I'm experimenting with MindAR for a client-project and having great success. Thanks for providing this resource!

My client is doing an exhibition where posters will be used as targets. So far I've manged to get an entire poster (hanging on a white wall) to act as a target.

My client wants to be able to use a subsection of a poster a target, so that we can position the model exactly relative to this subsection of the poster. Is this possible. I've tried to get it working simply by cropping the original poster and feeding it to the Image Targets compiler, but it has not worked.
