Hi friends,

Please help me how to set  Layer properties/Symbology/Display back ground value RGB to value 0 0 0 for all 200 raster files in once with python command?

I tried to use arcpy.SetRasterProperties_management but this is not the correct one.

Thank you in advance!

So much time spent and found it here. However, space, indent ...etc. enter.... is challenges!

import os, arcpy, arcpy.mapping

from arcpy import env

mxd = arcpy.mapping.MapDocument("Current")

lstas = arcpy.mapping.ListLayers(mxd,"*.img")

    for las in lstas:

    arcpy.ApplySymbologyFromLayer_management (las, r"C_RE.lyr\20101105t045002_01_or_mo.img")
