Sure. There are 2 specifications mentionned in http://gdal.org/frmt_pdf.html : - Adobe Supplement to ISO 32000: http://www.adobe.com/devnet/acrobat/pdfs/adobe_supplement_iso32000.pdf - OGC GeoPDF Encoding Best Practice Version 2.2 (08-139r3) : http://portal.opengeospatial.org/files/?artifact_id=40537 But I doubt you'll enjoy their reading (especially the ISO 32000 one). In practice the support has been developed by dumping existing files.
Yeah, I've looked at them before and thought of something more easily readable - but I will give them a second look anyway.
The GDAL PDF driver supports update of an existing PDF to add georeferencing to it. You can do that for example with the -a_ullr and -a_srs flags of the gdal_edit.py script. You can also look at the pdf_update_gt() test in https://svn.osgeo.org/gdal/trunk/autotest/gdrivers/pdf.py This is also documented in the "Update of existing files" section of http://gdal.org/frmt_pdf.html
Cool, thanks for the links! Frank _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
