ColorRamp

Resumen

ColorRamp provides access to a color ramp that is available in a project.

Debate

To reference a color ramp in a project, use the listColorRamps method on the ArcGISProject class. Once a color ramp is referenced, you can assign it to the colorRamp property that is available to the GraduatedColorsRenderer, GraduatedSymbolsRenderer, and UniqueValueRenderer classes.

Gets the name associated with the color ramp. A valid value is only available if a color ramp is referenced using the listColorRamps method on the ArcGISProject object. If a ColorRamp is returned from a renderer or colorizer, the name property will return an empty string because the name is not persisted with the renderer or colorizer.

ColorRamp example

The following script changes the colorRamp property of a GraduatedColorsRenderer to a color ramp named Cyan to Purple that is available in the project.

import arcpy, os, sys

relpath = os.path.dirname(sys.argv[0])

p = arcpy.mp.ArcGISProject(relpath + r"\\GraduatedColors.aprx")
m = p.listMaps("Layers")[0]
l = m.listLayers("Natural*")[0]

sym = l.symbology
colorRamp = p.listColorRamps("Cyan to Purple")[0]
sym.renderer.colorRamp = colorRamp

l.symbology = sym

p.saveACopy(relpath + r'\\SavedOutput.aprx')
