Ok, new report here : * Instead of using an HTML item which forces to load an external html file, I just use a classical Text item. I have checked the "Display in HTML" checkbox
* I setup an ID for this text box, for example "myid" * I can request the getPrint and add the parameter and content, for example ...&LAYERS=commune&myid=<h1>a small test</h1><br/><br/><p>lorem ipsum blablabl</p> * It seems to work, but I get a tiny tiny box with some unreadble text in it. I think I must pass some extra parameters to the fake X Server, like the screen size, etc. I will report further attempts Cheers Michael 2013/5/23 kimaidou <[email protected]> > I report my progress here > > I managed to get a PDF via the GetPrint request by following these steps > > 1/ Create a fake X server > Xvfb :99 -ac -noreset & > > 2/ Add the option in the fastcgi , for example > FastCgiConfig -idle-timeout 70 -maxClassProcesses 50 -minProcesses 3 > -init-start-delay 3 -restart-delay 20 -startDelay 15 -initial-env > DISPLAY=:99 LD_LIBRARY_PATH=/home/kimaidou/src/qgis/build/lib/ > > 3/ Restart Apache > service apache2 restart > > > After this, I tried the GetPrint request from my QGIS project with a > composer containing a HTML item.
