    Hi,

    If programming by yourself is not needed, you could perhaps use gdal programs, see http://www.gdal.org/

    If you have at least three tie points for an image, you can use gdal_translate to input tie points and gdalwarp to warp the image:

    gdal_translate -gcp pixel line easting northing -gcp ... scanned.tif tmp.tif

    gdalwarp tmp.tif result.tif

    gdal_translate can also be used to convert tif/tfw to geotiff, if that
    is enough for you.

    if anyone please convert the following tiff to geotiff please.Its very urgent http://www.zamzar.com/getFiles.php?uid=e9e62f2a6ab13d2c7ec48aac424c91d-e39896bf5b132be9&targetID=pmVo4ovEokn3e0OeWCcFSQ_I_I
