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.<br>
<br>gdalwarp may not be the solution to your problem. IMO, there is very little code overlap to integrate this into gdalwarp.cpp<br><br><div class="gmail_quote">On Tue, Jan 19, 2010 at 3:56 PM, <span dir="ltr"><<a href="mailto:SriRam.PrasadBhasker@rmsi.com">SriRam.PrasadBhasker@rmsi.com</a>></span> wrote:<br>

Hi.<br>
<br>
GDAL Warp generates a Resampled Output Image along with a TFW for a<br>
provided set of GCP's<br>
<br>
My question is .. is there any Parameter by which we keep the raw image<br>
untouched & generate only the TFW.<br>
<br>
By Adjusting the TFW parameters we can position the raw image @<br>
geopositioned Location..<br>
<br>
Any guidance would help immensely.<br>
<br>
