Summary
Performs a Bitwise Not (complement) operation on the binary value of an input raster.
Illustration
Usage
If an input is floating point, the values are converted to integer values through truncation before the bitwise operation is performed.
In bitwise operations:
- Binary values are stored in two's complement.
- The tools work on 32-bit integers.
- The leftmost bit position is reserved for the sign (positive or negative) of the value. If the integer is positive, the bit position is 0; if it's negative, the bit position is 1.
The Bitwise Not operation treats the sign bit as it would any other bit. If the input for a cell location is negative, the output is negative; if the input is positive, the output is positive.
See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.
Syntax
BitwiseNot (in_raster_or_constant)
| Parameter | Explanation | Data Type |
in_raster_or_constant | The input raster on which to perform the Bitwise Not (complement) 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
| Name | Explanation | Data Type |
| out_raster | The output raster. The cell values are the result of a Bitwise Not operation on the input. | Raster |
Code Sample
BitwiseNot example 1 (Python window)
This example performs a Bitwise Not operation on an input Grid raster.
import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outBitwiseNot = BitwiseNot("degs")
outBitwiseNot.save("C:/sapyexamples/output/outbitn")
BitwiseNot example 2 (stand-alone script)
This example performs a Bitwise Not operation on an input Grid raster.
# Name: BitwiseNot_Ex_02.py
