remove threshold imaq image

[eliel]

Hello,

I´m using labview 2011 with development vision.

I'm working with some images and created a function to enable and disable the image THRESHOLD.

I can open the original image and activate the threshold but can not get the image back to the original when I disable the threshold.

Does anyone know how I could activate it and deactivate it with a button?

Thank You.

1. Try to make copy of your image (with IMAQ Copy) then apply Threshold to copy.

2. Show your code here.

Here is the code.

The IMAQ Images transfreed by references, not by values. After thresholding you have no original image.

Use design pattern like this:

See attached VI too.

Hi

Place a slide to control either the min or max value of your threshold range and use the slider value change event in your event structure: like this

Hope this helps
