I agree with Jukka.<div>Working to a lower level of binding (through GDAL/OGR) would let other foss software leavarage the improvements.</div><div>I don't know Inkscape very much, but I've tried to import the latter example from Jukka (the multilayer PDF) and it keeps the layers correctly.</div>
<div>Working on the GDAL level is probably harder then doing the work on the Python level directly between Qgis and Inkscape, but I feel it would be far most used and useful to improve the GDAL PDF support...</div><div><br>

</div>There is heavy work going on with GDAL PDF driver <a href="http://gdal.org/frmt_pdf.html" target="_blank">http://gdal.org/frmt_pdf.html</a><br>
Mapserver can already make georeferenced PDF files like this with the trunk<br>
version of GDAL <a href="http://latuviitta.org/documents/Lahti_geospat.pdf" target="_blank">http://latuviitta.org/documents/Lahti_geospat.pdf</a><br>
Reading the geospatial info of that certain PDF needs TerraGo Toolbar which is<br>
an add-on to Adobe Acrobat reader. Here is another PDF output example<br>
<a href="http://latuviitta.org/documents/raitiovaunulinjat.pdf" target="_blank">http://latuviitta.org/documents/raitiovaunulinjat.pdf</a><br>
It is made with OpenJUMP derivative SkyJUMP and it demostrates using vector<br>
layers on to of a raster layer (tram lines in this case). User can toggle the<br>
layer visibility at least with Adobe Acrobat Reader. I am not sure if GDAL can<br>
do such layered output yet. However, I have a feeling that GDAL may soon be able<br>
to support direct conversion of raster files with OGR vector file overlays into<br>
layered and georeferenced PDF files. See recent PDF commits by Evan Rouault at<br>
<a href="http://trac.osgeo.org/gdal/timeline" target="_blank">http://trac.osgeo.org/gdal/timeline</a><br>
<br>
Perhaps that work will help you with the QGIS to Inkcape work flow. At least it<br>
might be good to study what could be done by feeding GDAL from QGIS before<br>
dublicating those functionalities into QGIS.<br>
