Overview

The example demonstrates how to overlay an image with a overlay with variable thickness.

 

Description

The example overlays a rectangle with variable thickness onto the image. The location of the rectangle is defined by the ROI the user selects during the execution of the VI. Since there is no overlay function that directly overlays an image with a rectangle of variable thickness, the example uses multiple overlays, so the resulting overlay appears to be a single rectangle of variable size.

 

Requirements

 Software

  • LabVIEW 2012 Base Development System (or compatible)
  • Vision Development Module 2012 (or compatible)

 Hardware

  • No hardware is necessary to use this example VI

 

Steps to Implement or Execute Code

  1. (Optional) Change the settings for 'Overlay Color' and 'Overlay Thickness'
  2. Run the VI
