Codebeispiel

ColormapToRGB example 1

This example converts the raster with a color map to an RGB 3bands raster.

from arcpy.sa import *
out_slope_with_colormap = ColormapToRGB("elevation_raster.tif")
out_slope_rgb_3bands.save("C:/arcpyExamples/outputs/elevtion_rgb_3bands.tif")

ColormapToRGB example 2

This example converts the raster with a color map to an RGB 3bands raster.

# Import system modules
import arcpy
from arcpy.sa import *

# Set the analysis environments
arcpy.env.workspace = "C:/arcpyExamples/data"

# Set the local variables
in_raster = "slope_raster.tif"

# convert the raster with colormap to a RGB 3bands raster
out_slope_rgb_3bands = ColormapToRGB(in_raster)

# save the output
out_slope_rgb_3bands.save("C:/arcpyExamples/outputs/slope_rgb_3bands.tif")
