Overview

The example demonstrates how to overlay an IMAQ image with another image semitransparently.

 

Description

This example allows for a semitransparent IMAQ overlay.  IMAQ overlay functions do not currently have support for transparency, so this VI manipulates the pixels to give a look of semitransparency.  It performs a weighted average between the overlay image and the IMAQ image. The level of transparency is determined by the transparency factor input.

 

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. Run the VI
  2. (Optional) Change the multiplier settings of 'Transparency Factor' and 'Coordinates of Overlay'
