Description

When classifying a raster to apply a colorscale, a very handy option would be to be able to equalize the histogram. I'm thinking on GRASS's r.colors here. The advantage of having this in QGIS is that QGIS can use the min-max (and histogram?) for a subset of the raster, based on what is displayed, for instance. A classification of colors based on a equalized histogram would make a great exploratory tool, since it would allow to see features on a raster that would normally be hidden by the usual color classification. https://grass.osgeo.org/grass70/manuals/r.colors.html
