Summary

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

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

LabelExplanationData 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

LabelExplanationData Type
Output raster

The output raster.

The cell values are the result of a Bitwise Not operation on the input.

Raster

BitwiseNot(in_raster_or_constant)
NameExplanationData 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

NameExplanationData Type
out_raster

The output raster.

The cell values are the result of a Bitwise Not operation on the input.
