Hi,
Is there an easy utility (linux commandline preferable, but windows OK) 
to de-skew a geo-referenced scanned map?
Typically the TFW files look like this:

0.317469
0.001049
0.000994
-0.317666
-19902.462151
-3208549.358736


Why is the row-rotation different from the column rotation?

I have 1268 images to deskew :-(

TIA,
Zoltan
