How to change the image display position on FP programmatically?

[Anne Zuo]

Hi All,

I need to change the IMAQ image display on FP programmatically.  I check the property node and find out it is read-only. Is there a way to do that?

Thanks a lot for any help.

Hi Anne,

In the subject line of your message you mention that you want to change the "image display position" while in the message body you mention that you want to change the "IMAQ image display". Which one of the two do you wish to change?

Which read-only property node did you try?

I am guessing you want to change the size of your IMAQ "Image Display" indicator and you tried the read-only "Bounds" property. To change the size of the image display area you can access the "Image Area : Size" property.

Hope this helps.

I have the same problem.

Could Anne please tell me how you do it?

Thanks!

use property "Position".

I attach a simple example. First select a grayscale image, run the vi and click "shift" button, you will see the image display moves.

Hope it helps.

Thank you very much Verg, that's very cool.

On the other hand, do you know how to display a picture automatically at the left top corner of the screen? There must be a setting to do this, and I am trying to display a picture full screen, but its position is always biased from the left top corner.

Thanks.

To add, I have set the picture position to the original point at 0,0.

But how to set the original point to be displayed at the top left corner of the front panel each time I run?

Thank you.

I use openG vis.  Goolge it and download it. It's free and open source. There is a vi called "Fit VI window to Content".

Hope it helps.
