World File Details

[Flavio Hendry]

Hi Kyle

I don't know of any software using the rotation parameters. ESRI
software should, as world files were "invented" by them as far as I
remember. 

Anyway, MapServer supports rotation. Be aware that you have to specify
Projection for every layer in the mapfile to be able to do that.

See:

Mit freundlichem Gruss / Best Regards
