Operators Functions
Operator functions allow you to perform arithmetic or logical operations between two images or between an image and a constant.
The following table lists the Operators functions. The functions in the Operators class are grouped according to the types of operations they perform. The first column contains the name of the class. The second column contains names of function subclasses. The third column contains names of individual function panels. Each Operators function panel represents one function.
