Save Complex Image to File using LabVIEW

[Justin__D]

Overview

This example demonstrates how to save complex data to an image file.

Description

Complex images are typically created when performing a fast fourier transform (FFT) on an image. Pixels in a complex image consist of a real component and an imaginary component. The complex image type cannot be saved to a file format that other programs can read.  When saving in other file formats, the phase (imaginary) information of the complex image will be lost.

This example can save a complex image to another file type including JPG, PNG, and BMP.  This examlpe uses an invoke node to take a "screenshot" of a front panel image display and save this image to file.  This does not save any of the complex information associated with the image but it does allow the user to save a "screenshot" of the complex image being displayed.
