[Qgis-user] reload WMS raster

[Nicolas Cadieux]

Hi,

Specify a tile size like 300x300 in the wms setting.  In your network option(Setting\options\network), you are able to increase the size of the cashe.  I know the first option works, the second option not sure but I do it anyway... 

Use "cache to speed up" in the rendering options.(setting\option\rendering).

Also, I usually have 2 wms layers at once.  One with more layers (Slow), and one with only one layer like the road or water (fast).  I keep only the second one on. When I am where I want to be, I turn on the first, more complex layer.

Each time I change anything, turning on or off layers, editing layers etc, the WMS reloads the raster even if there is no change in the underlying data of the raster. I have a slow connection and it drives me crazy to wait each time I move vertices. I often use ‘save as image’ and load the image, but I already have too many of those temporary rasters and still I find myself using sections or magnification where the rasters I copied are insufficient. Is there a trick to speed up the process of editing the canvas without the WMS reloading?
