Hello,My goal is to replace the values of one raster (of all the 3 RGB bands) with the values of another raster (also 3 bands) where the values of the initial raster meet some requirements, for example only where Band_1 (Red) = 205, Band_2 (Green) = 255 and Band_3 (Blue) = 194. The code bellow does not work saying something like the raster 205 is not supported...I also dont know how to loop through the RGB arrays...Initially I tried to do this in raster calculator but did not figure it out how to do it...Here I put the code where I want to replace the values of the Image17 with the values of Image16:import arcpy, os
arcpy.CheckOutExtension("Spatial")
arcpy.env.workspace = r"Z:\BP\TST"
Image16 = r"Z:\BP\TST\16.tif"
Image17 = r"Z:\BP\TST\17.tif"
Image16_red = arcpy.sa.Raster(Image16+"\\Band_1")
Image16_green = arcpy.sa.Raster(Image16+"\\Band_2")
Image16_blue = arcpy.sa.Raster(Image16+"\\Band_3")
Image17_red = arcpy.sa.Raster(Image17+"\\Band_1")
Image17_green = arcpy.sa.Raster(Image17+"\\Band_2")
Image17_blue = arcpy.sa.Raster(Image17+"\\Band_3")
if Image17_red == "205":
if Image17_green == "255":
if Image17_blue == "194":
output_obj = (Image17_red = Image16_red) & (Image17_green = Image16_green) & (Image17_blue = Image16_blue)
output_obj.save(r"Z:\BP\TST\output.tif")
Could you please give me a hint on how to solve this?Thank you very much
