Operator Properties

There are two types of operator properties: static and dynamic. You can change static parameters only during design phase in VisualApplets, whereas you can change dynamic parameters during design phase and during runtime. See the screenshot below for examples of static and dynamic parameters for the operator IS_GreaterThan.

Static and Dynamic Operator Parameters

Figure 186. Static and Dynamic Operator Parameters


In this sample design, set the following parameters:

Operator IS_GreaterThan:

Set the parameter Number to 600.

This identifies the grayscale of the edges. If you want to find out the grayscale of your edges, set a simulation probe before the IS_GreaterThan operator, run a simulation, and zoom into the pixels that contain edges and see which grayscale they have. This is a dynamical paramter, which you can alter during runtime.

Operator SCALE:

Set the parameter ScaleFactor to 255.

This augments the visibility of the edges. This is a dynamical parameter. However, to save FPGA resources, you can set this parameter to Static.
