All Implemented Interfaces:

GPTool

public class ATan
extends AbstractGPTool

Calculates the inverse tangent of cells in a raster. The ATan tool is contained in the Spatial Analyst Tools tool box.

Usage tips:

• In mathematics, all Trigonometric functions have a defined range of valid input values, called the domain. The output values from each function also has a defined range. For this tool:Note that here -? and ? represent the smallest negative and largest positive value supported by the particular raster format, respectively.
• The input values to ATan are interpreted as unitless.
• Output values are always floating point, regardless of the input data type.
• The output values from this tool are in radians. If degrees are desired, the resulting raster must be multiplied by the radians-to-degrees conversion factor of 180/pi, or approximately 57.296.See for examples of converting output values from radians to degrees.

Constructor Detail

ATan

public ATan()

Creates the ATan tool with defaults.

Initializes the array of tool parameters with the default values specified when the tool was created.

ATan

public ATan(Object inRasterOrConstant,
            Object outRaster)

Creates the ATan tool with the required parameters.

Initializes the array of tool parameters with the values as specified for the required parameters and with the default values for the other parameters.

Parameters:

inRasterOrConstant - the input for which to calculate the inverse tangent values. in order to use a number as an input for this parameter, the cell size and extent must first be set in the environment.

outRaster - the output raster. the values are the inverse tangent of the input values.
