Display a color image in front panel.

[heartland]

Hi there,

How do I display a color image in front panel? Which graphic indicator should be used to display a color image? I do not want to use Imaq WindDraw.

Thanks in advance.

You can use a picture indicator...(from the graph->controls palette). You find VIs to read in the picture in the picture folder in vi.lib.

I believe you'll find the PICTURE functions very useful for this. The nice thing about the picture functions is that you can keep daisy-chaining them together to add features....such as a grid, or a cursor, or even a photographic background. You can even animate the colors. Look in the Examples in the help files. They're pretty good.

Try this "draw flatten jpg to pic ctrl.vi"

Thank you for your VI. It works well. I need some time to understand it. I have many years experience in Labview and very new to color imaging. A quick question: How do I display a image in a fixed picture control no matter image's spatial resolution.

Thanks again.

Thanks very much, Mads. I will take a look at the picture control.

Thank you very much, Eric, for your help. I will take a look at the examples.

Me too, not really having much exp. in color imaging.

I am not sure if I understand your question, but if I do, fixing the property node "DrawAreaSize" for picture control should do the job.

Hope this is not a nonsense :<

Cheers!
Others might be able to give you a better answer.

Hi Ian,

Hope I did not mess up your name. DrawAreaSize does not do exactly what I want. My question was how to fit a image into a picture control in fixed size. Picture control does not resize itself to fit the images in different spatial resolution. Thanks again.

My Image Toolbox VIs can resize pixmap data, and display images. Support bmp, gif, jpg, png, tiff, wmf, emf, ico, etc. You can download demo at:
