LV Picture Control

How about a more full featured version hurling NI Eagles at stacks of PXI and cRIO units? 😄

(Of course the NI lawyers might take offense in abusing trademarked graphics, but it might be OK under the parody excemption of fair use.)

 I've tried to change the image control to rotate anothe image, but after I change the control and the property node the VI doesn't rotate the image. Is there something I'm missing to get the image to rotate?

I've attached my code and the new image I want to rotate.

Thanks!

Altenbach can speak to his specific implementation, but if you don't mind having .Net as a dependency, I posted some code here, that can rotate an arbitrary image at various horizontal and vertical points with various modes.  It works with your PNG image.

Thank you! I'll play around with it. Is there a way to get rid of the gray background of the picture? My original file doen's have a background. 

Thanks!

All you did was paste your image into the front panel. You need to read your file, unflatten it (it is 24bit, so use a different output when unflattening) and feed it into the machinery.

However, at 2400x2400, your picture is way too big. Make it 10x smaller in each dimension.

Thanks for your quick response. This really helps! I appreciate it!

The size of the image is not a problem for the .Net method, of course it is a slower than it would be on a smaller image.  The current image can be resized and rotated at about 8 times a second on my computer.  

As for the grey background that is because the pane that the picture box is in is grey.  My method supports alpha layers, and will apply them to the picture shown.  Since the background is grey, this is used on the image.  To change the background color, resize the control to make it smaller, so you can see the pane it is in.  Color it with the LabVIEW color tool, then right click the control and fit it to the pane again.  Now when it runs the background will be the color of the pane that you just picked.
