Raster band properties example

The following stand-alone script displays some properties for a raster band:

import arcpy

# Create a Describe object from the raster band
#
desc = arcpy.Describe("C:/data/preston.img/Band_1")

# Print some raster band properties
#
print("Height: %d" % desc.height)
print("Width:  %d" % desc.width)
print("Integer Raster: %s" % desc.isInteger)
