Feature request #8358
The composer should retry more than one time the retrieve of a tile from a layer wms
|Pull Request or Patch supplied:||No||Resolution:||fixed/implemented|
I know the composer will apply a tile strategy client size.
It work very well.
But sometimes in the print result(i use the pdf export) will appear one or more white rectangles as if the qgis composer was unable to retrieve some tile section.
Usually this is due to a network failure (iternet), or sometims to a temporary wms failure (due to too much requests)
I guess a good enhancement to bring the client tile strategy to a really good affordable using it on internet is to
enhance the driver to retry another time the request to the tile (when the first one was failing).
As suggest from Marco H. (http://lists.osgeo.org/pipermail/qgis-user/2013-July/023243.html)
The right solution probbly is to implement some logic in some module like QgsRasterDrawer or similar.
