IMAGESQR

Description

Finds the square root of the input raster channels and places the value in the specified output file.

Parameters

Name	Type	Length	Value range
Input1: Input raster channel(s) *	Raster port	1 - 1024
Result1: Output raster channel(s)	Raster port	0 - 1024
Replacement for Invalid Numeric Value	Float	0 - 1	0.0 - Default: 0.0

* Required parameter

Parameter descriptions

Input1: Input raster channel(s)

Specifies the input channel(s) to be processed.

Result1: Output raster channel(s)

Specifies output image channels to receive the image produced by taking the square root of the input image channels (DBIC).

The number of output channels (DBOC) must be the same as the number of input channels (DBIC).

Replacement for Invalid Numeric Value

Specifies the number used as replacement for invalid numerical values.

The default value is 1.0.

Details

IMAGESQR takes all the pixel values from the input channel(s) and calculates the square root value, placing those values in the output channel(s). If an invalid value exists, the value specified in the Replacement Value parameter is used instead.
