Parameters

Menu:   Measure > Parameters

Script:   selectParam, resetParam

Use this command to define parameters for automatic measurements.

Most of ImageWarp's parameters are scalars, i.e. they render one numerical result for each object (blob) measured. Unlike the scalar parameters, vector parameters render an array of values for each object measured. The examples of such parameters are Histogram, Moments, Radii. To access the individual elements of a vector parameter in your script, you have to use the following syntax:

   x= getParamValue("Histogram",3)

The operator retrieves the third element of the histogram measured for the last object and assigns it to x. See ImageWarp Language Reference for more details.
