History

#1 Updated by Maximilian Krambach over 9 years ago

The error lies in /usr/share/qgis/python/plugins/db_manager/db_plugins/spatialite/plugin.py line 231, in toMaplayer(self).

Instead of "rl.setContrast…" it should be "rl.renderer().setContrast…";

but still it won't work on multiband rasters (as in the example). They need to have their contrasts set for each Band displayed.

Commenting out the line makes the raster display nicely on (debian)QGIS 2.8.1
