The node can be found under Nodes > Input Nodes > Widgets > Video Display Input

Or by right-clicking on the respective widget itself and selecting Create related Node teams> Video Display Input

Node Properties

Display ID:
Enter the VideoInputDisplay ID.

Interval (ms):
Enter here the refresh interval for the incoming video stream.

Defining a region:
Select one out of the eight available regions from the drop-down.
When you click the Draw Region button left of the drop-down, you can draw a rectangle into the video feed corresponding to the selected region. The new region is automatically applied.

Selecting a color:
The eight color select buttons on top of the dialog correspond to the eight regions. Press on the respective color button to open a color picker and select a color.
Alternatively, select a region from the drop-down and press the Pipette button to extract a color directly from the video feed.

The currently selected region is indicated by a white frame around the color select buttons at the top of the dialog.

A number indicating the Match of the selected color within its region, as well as the regions' average R, G and B values are displayed below the color select buttons.

Node control

With Widget Designer version 6, all nodes support so called node commands. Node commands access functions (i.e methods) from a node and / or set a parameter (i.e. property).

Enter "node", followed by the according ID and a dot and a list will pop up showing all available commands for the node. For instance, Node1.TintColor.SetRGB(125,0,255), colors the node in purple.

Node output values

The node generates the following output separately for each region:

- AVG Red
- AVG Green
- AVG Blue
- Match
