IMAQ arraytoimage example

[Stephen]

Hi all,
Does anyone know of a Labview example utilising the IMAQ ArrayToImage funtion?
The LabView help files in this instance are not terribly "helpful".

Thanks in advance.
Stephen.

Hello,
An example of using the IMAQ Array to Image VI would be to create an 2D array of pixel values which is data type I16 or U8 or floating point values. Then input the array into the appropriate input parameter of the IMAQ Array to Image VI corresponding to your data type: I16, U8 or floating point. You only have to select one of the parameter types. You will also need to use an IMAQ Create to create a new image and feed that image into the image input for the IMAQ Array to Image VI.

As far as I can tell, I have done exactly as is recommended, but no image appears at the output. I haven't figured out a way of debugging this either. The vi is too simple !

Can you post your VI here so that we can see what is going on?

Thanks

Brian,
Thanks in advance for your help on this. I am trying to display an image as a eries of gray levels. The gray level depends on the value in the array. I suspect I am misinterpreting how things are working as there doesn't seem to be anywhere to set the gray levels or to set what palette is needed if you want to work in color.
Best regards

I'm not sure what is in this VI, but Labview crashes when trying to open it up. Any ideas why?

Andrey,
Thanks very much for your help. I'd give four stars, but it doesn't seem possible on replies to comments.

Brian,
I don't understand why Labview crashes, but Andrey Dmitriev seems to have found a solution. Thanks for your time.
