Yes, the GDAL PDF driver can be used to add georeferencing info to an existing PDF file. This is for example used in MapServer developement version in its PDF output. This is a matter of opening the file in update mode, and setting the appropriate info with the SetGeoTransform() and SetProjection() methods. > > Jim Bellenger > _______________________________________________ > gdal-dev mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/gdal-dev _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
