This example demonstrates how to create a partial transparent overlay over an image without the Vision Development Module (VDM).
When trying to create transparent portions of images using the Picture Functions in LabVIEW, your only option is to the Create Mask function. However, it does not allow for partial transparency.
The work around to achieve partial transparency is to average the pixels you would like to be transparent with the pixel values of the original image. See the attached VI for an example of performing this feature.
LabVIEW Base Development System 2012 (or compatible)
If running in a Real-Time context, you will need the LabVIEW Real-Time Module 2012 (or compatible)
