Description

I have a 4 band raster loaded into QGIS, under the layer Symbology I've chosen "Paletted/Unique values" and selected Band 3 to be the source of those values. Selecting classify with random colors, all the vales are represented correctly, however the actual raster is rendered based on Band 1, not based on the selected Band 3. I would expect selecting band 3 could cause it to use band 3 in the rendering.

#1 Updated by Andrew Harvey over 1 year ago

My workaround is to use `gdal_translate -b3` to pull out band 3 into a 1 band image and use that in QGIS.
