I've been experiencing a problem with the QGIS print composer. I am working on a Linux Ubuntu platform (Release 12.04 (precise) 64-bit) and I am using QGIS 2.0.1 Dufour.
I need to export a number of maps I have recently created, in either JPG or PDF format (in both 300 and 600 dpi), however, while I am trying to export them using the QGIS print composer the whole system crashes and shuts down immediately!
A pop out window appears and the the error it gives me is the following:
Java script problem: The script on this page appears to have a problem. Do you want to stop the script?
Whenever I choose -NO- (Not to stop the script) nothing is functioning, unless I choose the option -YES- (To stop the script) so apparently my QGIS project/ workspace immediately shuts down!
Could you give me any hints on how I could fix this problem?
I have already tried to export my maps using much lower dpi (100 and 150, etc.) but unfortunately it still gives me this error (!)
I have already checked previous posts/ replies and I have to mention that I have checked my labelling already. In QGIS 2.0.1 Dufour there is no 'old' and 'new' labelling. I do use however transparency and shadow in my labels.
I just figured out what the problem is! I've been using as background the Google Satellite OpenLayers Plugin, which uses the EPSG code:3857. My population density raster layer is in WGS84, and I have set the CRS of my QGIS Project (from the Project Properties) to be WGS84. So when I was trying to export it using the Print Composer my whole system was crashing!
What I still have to figure out though is how to make my population density raster look better in terms or pixelization. When I set my Project's CRS as WGS84 (EPSG:4326) my raster image looks absolutely fine but crashes if I try to export it as PDF/JPG, on the other hand if I set the CRS of my project as WGS84 Pseudo Mercator (EPSG:3857), my raster seems to pixelate when I make it large.
Any ideas on how to visualise it properly?
