Summary

Performs a Bitwise Not (complement) operation on the binary value of an input raster.

Illustration

OutRas = BitwiseNot(InRas1)

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, the following are true:

  • 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.

• If the input is a multiband raster, the output will be a multiband raster. The tool will perform the operation on each band in the input.

• If the input is multidimensional raster data, all slices from all variables will be processed. The output will be a multidimensional raster in CRF format.

Parameters

Dialog

Label	Explanation	Data Type
Input raster or constant value	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 specify a number for both inputs, the cell size and extent must first be set in the environment.	Raster Layer; Constant

Return Value

Label	Explanation	Data Type
Output raster	The output raster. The cell values are the result of a Bitwise Not operation on the input.	Raster

Python

BitwiseNot(in_raster_or_constant)

Name	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 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
