I'm a Raster Design newbie.
We have five .sid files which, all together, cover an entire county. These files are in the neighborhood of 600mb (each) and consequently put a lot of strain on a workstation.
What I would like to be able to do is crop a given area out of one of these .sid files. When I attempt this, I get a message saying that the file format is not editable. I am hesitant to 'save as' because (correct me if I'm wrong) a sid file is compressed and the resulting image file would be huge.
We do not currently have any software in-house that will edit sid files and I would like to be able to work with these files without losing too much time.
Any suggestions would be greatly appreciated.
