Andrea, Thanks so much. I'm not sure I would have figured that out on my own. I also found that I needed to include the min and max values from the statistics. Here is my final code if anyone else is trying to do this.
layer = iface.activeLayer() provider = layer.dataProvider() stats = provider.bandStatistics(1, QgsRasterBandStats.Min | QgsRasterBandStats.Max) min = stats.minimumValue max = stats.maximumValue # Get the Reds default colorramp style = QgsStyle.defaultStyle() ramp = style.colorRamp('Reds') color_ramp = QgsColorRampShader(min, max, ramp, QgsColorRampShader.Interpolated) color_ramp.classifyColorRamp() raster_shader = QgsRasterShader() raster_shader.setRasterShaderFunction(color_ramp) # Create a new single band pseudocolor renderer renderer = QgsSingleBandPseudoColorRenderer(provider, layer.type(), raster_shader) layer.setRenderer(renderer) layer.triggerRepaint() Thanks, Calvin On Wed, Jun 22, 2022 at 9:47 PM Andrea Giudiceandrea <andreaer...@libero.it> wrote: > *C Hamilton* adenaculture at gmail.com > <qgis-user%40lists.osgeo.org?Subject=Re%3A%20%5BQgis-user%5D%20PyQGIS%20code%20on%20raster%20image%20-%20What%20am%20I%20doing%20wrong%3F&In-Reply-To=%3CCABPxTTq_rYo25hS2NdGZv4fzeQZQ%3DG%3D7NiJQK1cEyFAdGrSL9g%40mail.gmail.com%3E> > *Wed Jun 22 08:36:45 PDT 2022* > ------------------------------ > > color_ramp.setColorRampType(QgsColorRampShader.Interpolated) > > > Hi C Hamilton, > I think you are missing to classify the color ramp here: > > color_ramp.classifyColorRamp() > > > Best regards. > > Andrea Giudiceandrea > >
