[Qgis-developer] Impossible to keep QGIS 2.4 while updating QGIS master (osgeo4W nightly build)

Hello, I use OsGeo4W to install both QGIS stable and master releases. Due to the bug of QGIS 2.6.0-1 that crashes QGIS and ruins some older project file, I decided to not yet upgrade to 2.6 (and keep 2.4) but still update nightly builds. The first time I got 2.7, I choose to keep 2.4. After the

[Qgis-developer] Viewport rotation: QgsMapCanvasMap and angles

After many hours trying to figure out who was ruining my vector data angles I finally found the QgsMapCanvasMap::paint method complaining about DIFFERENT SIZE of image and item. Indeed the documentation for QPainter::drawImage(QRect, QImage) says that the image is scaled to fit the rectangle,

[Qgis-developer] QgsVectorFileWriter.writeAsVectorFormat() created geoJSON Points in 2.4, now Multipoints in 2.6

Hello In 2.4, when writing geoJSON, QgsVectorFileWriter.writeAsVectorFormat() created Point features. In 2.6, this seems to have changed to Multipoint. Is this intentional? If so, why? Thanks Tom Tom Chadwin, UK National Parks Portal Manager Telephone: 01434 611511 Mob: 07881 109617 Web:

[Qgis-developer] Heatmap renderer: caching possible?

Hi, I tried the new heatmap renderer in QGIS master. It works nicely. I wonder if we could introduce a caching mechanism in a temporary raster layer to speed up zooming and panning? The idea would be to recreate the heatmap every time the project is loaded and then cache it while the project
