[gdal-dev] Problems with transform raster image

[Chaitanya kumar CH]

Jan,

You need to assign not only the projection of the source file but also the
geographical extents. The easiest way to do this is by adding GCPs to it
using the -gcp option of gdal_translate to create a new tif file. Use the
four corners of the image. Remember that the top left of the top left pixel
is (0,0) and bottom right of the bottom right pixel is (width,height).
