So I need to include the extent of a river into my map, but only have a raster file that shows the outline of the river with a blank (white) background:
Is there any way to crop this file so that my result is a raster which includes only the river without the white background so that I can put the layer above for example a ortho and still see the ortho with the river on top?
Alternatively, a raster to vector conversion should work as well, if possible...!?
I hope I made myself clear... Thank you very much for any help!
