[gdal-dev] Coordinate space to pixel space with image rotation in python

[Nicolas Cadieux]

Hi,

It's easy to go from coordinate space to pixel space in python using 
something like.

pixel_x  =  int(-124114.3  -  geo_transform[0])/geo_transform[1])

What is the trick when there is an image rotation?  Also, as a second 
very beginner question, what is the difference between geo_transform[2] 
and geo_transform[4]?

Thanks in advance!
