Custom Watermark Logo on FP

[Guruthilak]

Hello, 

Is it possible to add a custom watermark logo on the frontpanel (at the specified location depending on the FP Size)?

When LV is launched in the "Evaluation mode" you can see the NI logo on the right hand lower corner.. I would like to implement the same for on of my GUI screen.

If you place your watermark image on the front panel (as a png or bmp etc) you can then programmatically show/hide it using the VI property nodes. You can also change the position/size.

You need to look at the decoration properties of front panel

My colleague has pointed out a better solution - that would be to import your watermark as the TRUE image on a boolean indicator and have a transparent FALSE image. You could then simply wire a TRUE/FALSE condition to the indicator to determine whether it is displayed

Be aware that overlapped controls/indicators can place an additional load on the CPU.

If your watermark is visible above a graph/chart that is updated at a high rate, you may see your CPU load increase significantly.

If you are using LabVIEW 8.20 or later, you migtht also consider using the panel properties to assign wallpaper. I believe that this technique does not impose additional CPU load...

hello.

The idea looks good (both the png and the using the bool indicator) but i am not that convinced...Is there any other better way to do the same...Like as i mentioned the way NI puts their watermark on the Eval version and the position gets changed depending on the FP size...

And did you try the wallpaper option?

[Guruthilak]

Yep...

If you experiment with the  stretch options, you should get very close, if not exactly, what you want. If I remember, the watermark maintains it's position relative to the bottom corner as you make the front panel larger or smaller. I've played around with a jpg image and placed the logo in the bottom corner.

In trying the wallpaper, I can only Tile, Stretch, or Center it.  How do you get it to lock to the bottom right of the screen?

Thats exactly the question i had asked in the original post
