Overview

This VI takes an image and incrementally removes or "fades" each color plane of the image individually.

 

Description

The VI takes the selected image, uses the ExtractColorPlanes VI to separate the Red, Green, and Blue color planes, and uses the ImageToArray function to convert these planes into a 2D array of pixel intensity values. Each array is multiplied by a constant that is less than 1 in order to reduce the brightness of each plane's pixels during each iteration of the for loop. Each plane is then converted back into an image, and the corresponding plane in the original image is replaced.
