Hi!
I'm having a problem and hoping to get help to resolve it.
I'm currently working on a project where I have to search muximum of raster layers. The problem occurs when I subtracted one raster from another, by the fact that one is polygon and the other is polyline. At the end I'm left with the display, which is the size of polyline and everything else disappears. How can one deduct one raster (polyline) from another (polygon) without losing the rest of the display?
Thank you for helping me.

Example:
[url=http://b.imagehost.org/view/0125/skupno1][/url] minus [url=http://d.imagehost.org/view/0815/skupno2][/url] = [url=http://b.imagehost.org/view/0635/skupno3][/url] (the whole work area, and not only polyline, as a get)
