This is mainly relevant to WMTS/xyz and other tiled images based (online) data sources (for what I know). Because those tiles actually are server side cached, they have off course one true resolution: in which a 256x256px tile is shown on a 256x256px area of the mapcanvas. When you load such layers in QGIS, QGIS can rescale those tiles, they will be rescaled then, often not making the image prettier. The idea of the native resolution is for what I know: select the tiled layer, the select the "Zoom to native resolution (100%)" and then QGIS will switch to one of the (native) zoom level scales of the tiled layer. It more or less works the same as with the Tile Slider. Maybe (others plz confirm) this also works this way for raster images like geotiffs... Hope this helps, Regards, Richard Duivenvoorde _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
