Available with Image Analyst license.

Summary

Changes the sign (multiplies by -1) of the cell values of the input raster on a cell-by-cell basis.

Illustration

OutRas = Negate(InRas1)

Usage

  • If the input is integer, the output raster will be integer type. If the input is floating point, the output raster will be floating point.

  • 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 to be negated (multiplied by -1).

To use a number as an input for this parameter, 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 input values negated (multiplied by -1).

Raster

Negate(in_raster_or_constant)
NameExplanationData Type
