Usage

  • Two inputs are necessary for this bitwise operation to take place.

  • The order of inputs is irrelevant for this tool.

  • 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 And operation treats the sign bit as it would any other bit. If one or both inputs for a cell location are positive, the output is positive; if both inputs are negative, the output is negative.

  • If both inputs are single-band rasters or one of the inputs is a constant, the output will be a single-band raster.

  • If both inputs are multiband rasters, the tool will perform the operation on each band from one input, and the output will be a multiband raster. The number of bands in each multiband input must be the same.

  • If one of the inputs is a multiband raster and the other input is a constant, the tool will perform the operation using the constant value for each band in the multiband input, and the output will be a multiband raster.

  • If both inputs are multidimensional raster data with the same number of variables, the tool will perform the operation for all slices with the same dimension value. The output will be a multidimensional raster in CRF format. The variables in the inputs must have at least one common dimension and one common dimensional value for this tool to process; otherwise, an error will occur.

    If both inputs have one variable but different names, uncheck the Match Multidimensional Variable geoprocessing environment (set arcpy.env.matchMultidimensionalVariable = False in Python) before running the tool.

    If one of the inputs is a multidimensional raster and the other input is a constant, the tool will perform the operation for all slices for all variables using the constant value, and the output will be a multidimensional raster.

Parameters

LabelExplanationData Type
Input raster or constant value 1

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 specify a number for both inputs, the cell size and extent must first be set in the environment.

Raster Layer; Constant
Input raster or constant value 2

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 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 And operation on the two inputs.

Raster

BitwiseAnd(in_raster_or_constant1, in_raster_or_constant2)
NameExplanationData 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 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 specify a number for both inputs, the cell size and extent must first be set in the environment.
