Hi, Could it be possible to make GDAL PDF driver (http://gdal.org/frmt_pdf.html) to apply automatically -spat filter for the OGR_DATASOURCE layers which are to be drawn on top of raster layers? The values for the filter could be captured from the raster layer extents.
Now by default all the features from the vector layer are inserted into the PDF document. The features which lie outside the map borders on the map are rather unusable for users because it is impossible to show the features on a map even it is possible to select the features from the list and show the attributes. However, I suppose that usually people suppose that the map and feature list suit together. I can imagine that there could be some troubles in automatic construction of -spat filter if the PDF targer srs is different than the native srs of OGR_DATASOURCE. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
