"overlay" over which item?
When you are using graphs you can use the "Plot Images.Front" property to place a crosshair image over the plots. The IntensityGraph also knows that property…
I am using an API from the camera manufacturer, which with the help of .NET api can acquire w/o the need of the Vision module. I am grabbing images from the live feed, and covert to Pixmap, then save to JPG file. I only need to put one simple cross hair (red) in the centre of the live feed.
so you are using 2DPictures in LabVIEW.
I only need to put one simple cross hair (red) in the centre of the live feed.
There are a lot of drawing functions for 2DPictures! You can easily draw two red lines "in the center" of the mage(s)…
(You also could fiddle with the Pixmap data directly as they contain "simple" pixel arrays…)
Thanks for the tip! I found one other topic, where you suggested using these functions:
I will take a look and give it a try! Thanks again!
Million thanks Gerd! Since I am not familiar with these functions, and I am gonna use this app for only temporary stuff, I am too lazy to spend time figuring out how to make a cross from two lines. Instead, I just putted a circle... need only to center it more accurately, and all is done. 🙂
