[gdal-dev] Cropping to another image?

[Daniel Clewley]

Hi,

I did something similar to what Doug suggested using the GDAL python 
bindings to get the size, projection and pixel size of an image, then 
cropping and re projecting to match using gdalwarp.
You can view the code at:

Hope this helps,

Thanks,

Dan
