arcpy.mp adding excluded values and reclassify

Trying to get implement an ArcMap (arcpy.mapping) to ArcGIS Pro 2.7

Here's what I have in ArcMap:

fringe_shades = os.path.join(os.path.dirname(__file__), "lyr", "Fringe{}.lyr".format(cycles)) outlyr = arcpy.mapping.Layer(fringe_shades) pth = os.path.dirname(rast.catalogPath) outlyr.replaceDataSource(pth, "NONE", os.path.basename(rast.catalogPath)) outlyr.symbology.excludedValues = ex_str outlyr.symbology.reclassify() outlyr.name = results # add to map mxd = arcpy.mapping.MapDocument("CURRENT") arcpy.mapping.AddLayer(mxd.activeDataFrame, outlyr) arcpy.RefreshActiveView()

I can't see a way to apply an exclusion and reclassify in arcpy.mp. Here's what I have so far. I don't seem to be able to add my layer to map like I did in ArcMap as I m.addLayer doesn't seem to let me add a geoprocessing layer object to my map. So I'm adding it using the GP environment.

outlyr = arcpy.MakeRasterLayer_management(rast.catalogPath, results) fringe_shades = os.path.join(os.path.dirname(__file__), "lyrx", "Fringe{}.lyrx".format(cycles)) outlyr = arcpy.ApplySymbologyFromLayer_management(outlyr, fringe_shades, None, "UPDATE") parameters[5].value = outlyr arcpy.SetParameterAsText(5, outlyr)

It seems like I should be able to use the arcpy.mp.Layerfile() class to access a Layer object, but I don't seem to have anything like the .reclassify() method.

The ApplySymbologyFromLayer tool works with a geoprocessing layer object, applying new data ranges, but then I can't exclusions and reclassify. I had to write a separate tool to apply exclusions after I added the raster layer tot he map using CIM access -- but I can't reclassify, just turn the pixels off by setting the exclusion values:

# use CIM to set exclusion ranges p = arcpy.mp.ArcGISProject("CURRENT") m = p.activeMap ly = m.listLayers(parameters[0].valueAsText)[0] lyc = ly.getDefinition('V2') lyc.colorizer.exclusionRanges = [-.0001, .0001] ly.setDefinition(lyc)

This works for me, but wish I could figure out how to do it in the main tool.

~~Good~~ Great news, the ArcGIS Pro dev team is working on this. Thank you @JeffBarrette
