Overview

This example shows how to take a histograph of a color image and display it on a graph.

Description

After creating a temporary memory location for a color RGB image, IMAQ ReadFile.vi reads in an image from a specified file path and outputs the image to the IMAQ ColorHistograph.vi. The three planes of the image are unbundled to pull out the red, blue, and green data arrays and are then built into a 2D array to be displayed on a graph.

Steps to Implement or Execute Code

  1. Specify the File Path to your desired image on the Front Panel
  2. Run the VI

Requirements

Software

LabVIEW 8.6 or later
