Hi Bill,
First of all, thanks for your reply.
It seems ti be what I'm looking for, but unfortunately I have some 
problems with documentation.

In OGRGeometry class I foud this two methods:


As I said I'm working to a C application, so I shall use these functions:


But I found a reference only for the OGR_G_Intersects() function...

Furthermore, I cannot understand HOW to create two geometry from a 
geo-referenced image.
Someone can help me?
