So this is the question: Is it possible to determine for NI Vision whether there are dark characters on a light background or light characters on a dark background for any selected ROI?
So this is the question: Is it possible to determine for NI Vision whether there are dark characters on a light background or light characters on a dark background for any selected ROI?
Is this formula the same to one Vision Module uses to convert RGB images to grayscale? It is important because I'm going to use in dynamic determination whether there are dark characters on a light background or light characters on dark background.
There is an easy sample: two buttons Start and Pause, and String Box.
Event Structure has case Value Change for Start button.
If Start button is pressed value in String Box increases each second (I used Loop Structure).
After you have pressed Pause button loop execution pauses and waits until you press Pause button the second time.
The problem is: event for Pause button is not handled until event handling for Start button has been finished
Hi evreybody,
I've faced two problems with Dialogs in LW.
1.) I need to create a Two Button Dialog Form with some Check Boxes on it.
2.) Before Dialog starts, Enabled State for some Check Boxes should be changed to Disabled programmatically.
I am a newbie in LabWiev scripting and and I'll appriciate your help very much.
