how do I extract Image data?

[Andy2]

Hi,

I am looking to pull out the image data from the information bar along the bottom of an image - specifically, the pixel value and coordinate information. Is there a way to extract the information?

Thank you,

Andy

This thread *may* be relevant...Someone was trying to control a instrument based on the cursor position in an image IIRC....

Hello Andy!

Thank you for contacting National Instruments.  What you are doing can easily be accomplished by using a VI Server Reference.  When you use this reference you can select it to be image (which is the name of the image control on your front panel) then wire it to a property node and extract the "Image Information String".  This should give you all of the information you need.  I am posting an example of how to do this.  Let me know if you have anymore questions.  Thanks and have a great day!

Hi,

Sorry to be painful - I only have version 7.1, and so I can't open your attachment. I have had a fairly thorough look (I think) for what you suggested, and I canno' find it. Is there any chance you can save your 'HL snap.vi" for an earlier version of labview?

Cheers and apologies,

Andy

Hello Andy,

Here is the 7.1 version of the VI I posted.  I hope it helps.  Have a great day.
