Hi,

Seems to be the same functionality and with the same name as in ERDAS Imagine.
OSSIM can do it, see page 9 in this document
http://download.osgeo.org/ossim/docs/pdfs/ImageLinker_Tutorial.pdf
I am not sure how good OSSIM is with vector layers. OSSIM itself is getting
better with vectors but Image Linker is quite old and not developed any more.
However, it will not hurt to have a look at OSSIM if you want to do some serious
raster processing.
