◆ getBoundingRect()

ossimIrect ossimPolyCutter::getBoundingRect ( ossim_uint32 resLevel = 0 ) const

This will return the bounding rect of the source.

We can have several sources which are in a chain to modify the bounding image rect. lets say you are next to an image handler then it will return the bounding rect for that image. If you are at the right side of a resampler then you will get a bounding rect along the image view plane. This is going to be a very import method for both image writers, mosaics or anything that needs to operate only within the bounds of an image.
