Hi Sandro, How are you thinking of implementing this? In the map canvas only? I don't know yet, that's why I'm asking. Ideally, I think this should be supported in the map renderer - QgsMapRendererJob. Would that be similar to considering it an additional transformation on the input data, like reprojection ?

As a result all labels, symbology, etc also get rotated, which isn't ideal. If support for rotating maps was added to the actual map renderer then the composer would also benefit, as we'd be able to properly rotate the map without messing up labels and symbology.

[Qgis-developer] PostGIS tables with missing gemoetries: how to handle them?
Hi all. If one has a pg table with records with a missing geometry (e.g. there are records with a geom in a point column, others in a line column, others with both), the table will show only the records with a geom; if I click on Show all, I also get records without a geom. Of course, selecting a record like this and clicking on Zoom to selected does nothing. I'm unsure this is the least confusing behaviour for the user: opinions?

Re: [Qgis-developer] PostGIS tables with missing gemoetries: how to handle them?
Hi, I wasn't aware of this. Although I do not understand why one should put points and lines in the _same_ table, geometries are allowed to be NULL if the field does not have a NOT NULL constraint. I see two possible solutions 1) mark the dataset as having no geometry 2) (preferred) do only load datasets which have a geometry reasoning: As one can load any relation geometryless I would assume when loading the relation _with geometries_ there are geometries contained. I am aware that solution 2) can be achieved with the user applying a filter like codegeom_column IS NOT NULL/code to the layer but that's for advanced users only Bernhard Am 20.11.2014 14:07, schrieb Paolo Cavallini: Hi all.

If you want to test, you need the pyopengl bindings:

I've test personnly on several machine and cannot say if the crash is
reproductable.
Someone has any hints of path ?

I guess there would need to be some rotation knowledge at various levels for things to be flexible enough. Yes, for map rotation to work properly, its delta would have to be passed into the calculations for each type of labeling placement, to provide 'expected' results. Such a delta would have to include not only the rotation but also the new location of the label's point of reference. Towards that end, I would say the most straightforward means of implementing map rotation for effective labeling is to pre-rotate the duplicated, temporary feature geometries first, before they are acted upon, i.e. before extent (view port) clipping, etc., which would be prior to sending into the PAL library for processing. Such an approach should keep from having to pass the rotation offsets into the labeling calculations, since the rotated features would already be in their output juxtaposition. Maybe the feature pre-rotation could be done in the map renderer, prior to sending to the labeling engine.
