[gdal-dev] Subsetting based on geo-coordinates.

[Belaid MOA]

Hi Everyone,
 Sorry to bother again! I am looking for a cheap/dirty way of subsetting a GTiff image based on a rectangle specified in the geo-coordinates. Does GDAL has already something for that?   

 Thank you very much in advance.

With best regards.
