How do I display an array using vision tools

Hummer1 — Tue, 15 Jul 2008 14:00:12 GMT

I have an array of data that I would like to display on the screen. When I use the picture functions they put a border around the image which is not helpful. I noticed the "IMAQ WinDraw" and used it to display data I got from a Tiff file (without the border)...but there doesn't seem to be a path from an array directly to the windraw function without going through the file process. I'm sure I have missed something...but what is it?

Thanks in advance for your help.

Actually, if I understand your question correctly, you will just need two functions:
IMAQ Create
IMAQ ArrayToImage

You can then use the Front Panel control "Image Display" to display the image.

I do not seem to have IMAQ ArraytoImage anywhere in the help files or in the system. Where can I acquire such a wonderful piece of software?

Not Humming.

Hey, Chris....no kidding.

I have the vision tools and LV Developer Suite and there is no IMAQ Array toImage that I can find. Is there one in the vision developer module?

Look here. It will be in this sub-palette

Vision and Motion >> Vision Utilities >> Pixel Manipulation

Hummer,
Can you post a screen shot of your function palate?

The only function in the pixel manipulation palate is the IMAQ ImagetoArray ... that's it.

Should there be more?

Sorry ... havn't downloaded the Image posting stuff yet...

It sounds like you need to install the Vision toolkit again.

Hi Hummer,

It looks as if you do not have the Vision Development Module installed for this version of LabVIEW (this is a separate purchased software). Most likely, you have installed the free download of Vision Acquisition Software (this comes with all of our IMAQ hardware, as well).

You can refer to this Knowledgebase article to reference the functions that come with the free download of Vision Acquisition Software, without purchasing Vision Development. Unfortunately, the IMAQ Array to Image function is not included with the free download.
