I was thinking about something simple like taking the extents from the master raster layer and clipping extra layers with it. Equivalent to running gdal_translate -projwin ulx uly lrx lry and appending what gets clipped as a new PDF layer. OGR layers are already trimmed this way. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
