Visually Display and Manipulate Arrays

[Eden_S]

Overview
his example displays an array as different coloured pixels in a 2D picture and allows the user to change the individual values.

Description
This example will build a simple 100x100 array of integers between 0 and 2 and display these as different coloured pixels in a 2D picture display. The user then has the ability to change the individual values (or pixel colours) by clicking on each pixel or, alternatively, to change a large group of pixels using a ROI selector.

Requirements

• LabVIEW 2012 (or compatible)
• IMAQ/IMAQdx drivers

Steps to Implement or Execute Code

1. Run the Visual_Array.vi and notice that a randomly generated 100x100 array of 0s, 1s and 2s is generate as 'Original Array';
2. Use either the pixel selector or ROI selector to change the values of pixels in the 2D picture display. You can select which colour/value to change to using the drop-down menu.
3. Hit 'Set New Pixels' to write these new values to 'New Array' and notice that the values have changed between Original and New Array.
