[Gdal-dev] gdal_translate with polygon clip option

[SriRam Prasad Bhasker]

Hi.

Using Gdal_translate we can clip an Image with the below options (in a 
rectangle)
        [-srcwin xoff yoff xsize ysize] [-projwin ulx uly lrx lry]

Is there any option by which we can clip an Image Irregularly .. Thru a 
Set of Points that form a closed Polygon ????
Images will be rectangular anyway.. If we can fill the Outer regions of 
Polygon with Nodata value.. this will be of great help.


cheers
