Re: [Qgis-developer] Rendering active map symbol as QPixmap
Hey Andrew, This is how I did it with Roam to get all the legend items for the layer: items = layer.rendererV2().legendSymbologyItems(ICON_SIZE) That will give you a list of:Text - Icon pairs if you are using the rule base renderer you get can the symbol for the rule and paint that into a pixmap, however note that one feature can have many symbols so you will have to use the method that returns a list for all the symbols. Depending on what you are doing legendSymbologyItems might give you what you need without extra work. - Nathan On Fri, 8 May 2015 at 07:00 Andrew McClure wrote: > Any takers for this one?

[Qgis-developer] Rendering active map symbol as QPixmap
Any takers for this one? I'd like to render the active symbol for a layer as a QPixmap in a dialog. I have got this far: s = layer().rendererV2() key = s.rootRule().findRuleByKey(s.rootRule().ruleKey()) This tells me the active rule key to be rendered but how to get the image data? Perhaps I am barking up the wrong tree here? Thanks ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
