Usage

Syntax

BitwiseOr (in_raster_or_constant1, in_raster_or_constant2)
ParameterExplanationData Type
in_raster_or_constant1

The first input to use in this bitwise operation.

A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment.

Raster Layer | Constant
in_raster_or_constant2

The second input to use in this bitwise operation.

A number can be used as an input for this parameter, provided a raster is specified for the other parameter. To be able to specify a number for both inputs, the cell size and extent must first be set in the environment.

Raster Layer | Constant

Return Value

NameExplanationData Type
out_raster

The output raster.

The cell values are the result of a Bitwise Or operation on the two inputs.

Code Sample

BitwiseOr example 1 (Python window)

This example performs a Bitwise Or operation on two GRID rasters.

import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outBitwiseOr = BitwiseOr("degs", "negs")
outBitwiseOr.save("C:/sapyexamples/output/outbitor")
BitwiseOr example 2 (stand-alone script)

This example performs a Bitwise Or operation on two GRID rasters and outputs the result as a TIFF.

# Name: BitwiseOr_Ex_02.py
# Description: Performs a Bitwise Or operation on the binary values
#              of two input rasters
# Requirements: Spatial Analyst Extension

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

# Set environment settings
env.workspace = "C:/sapyexamples/data"

# Set local variables
inRaster1 = "degs"
inRaster2 = "negs"

# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")

# Execute BitwiseOr
outBitwiseOr = BitwiseOr(inRaster1, inRaster2)

# Save the output 
outBitwiseOr.save("C:/sapyexamples/output/outbitwiseor.tif")
