[gdal-dev] gdalwarp query

Prasad,

gdalwarp stretches the image to fit to the GCPs.

The situation you described is only possible if the GCPs can be located with
a first order polynomial. There will be no need to touch the image file
except to read its filename and the dimensions. In that case you just need a
small script to generate the world file.

gdalwarp may not be the solution to your problem. IMO, there is very little
code overlap to integrate this into gdalwarp.cpp
