[mapserver-users] Cut from raster data files

[Iacovlev Pavel]

Good day all.

	I have some raster data (.tif & .tfw) and created the index file with gdal 
index. Now I need too "cut" a polygon (I input the polygin data 
x0,y0,x1,y1,x2,y2...xn,yn) from this raster files, it's ok if the resulting 
image is not transparent, but I need to preserve image type & dpi.

What are the possible ways to do this ? thank you in advance Iacovlev Pavel.
