I am trying to clip a raster by shapefile perimeter using the clip tool. The percentage has been jumping between 0% and 100% for over an hour, back and forth, climbing to 100% then dropping down to like... %35 or so all over again. Does anyone know how to fix this? I'm desperately trying to cut down this raster file so I can continue doing my work, since it has to re-draw the entire raster every time I add a point to a point shapefile. Arg!
