Overview

This example demonstrates how to fade an IMAQ Image to black iteratively.

 

Description

This VI takes the selected greyscale image and uses IMAQ ImageToArray function to convert the image into a 2D array of pixel values. This array is multiplied by a constant that is less than 1 in order to reduce the brightness of the pixels during each iteration. The array is converted back into an image and displayed. The process repeats multiple times.

 

Requirements

 Software

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

 Hardware

  • No hardware is necessary to use this example VI

 

Steps to Implement or Execute Code

  1. Download and open the attached file
  2. Run the program
