Property Node Width and Height

[oglakan]

I have a Jai cv-a70ge camera and the image is 767x576.  When i set the height and width in the property node for the grab, it gives me an error saying they are out of range.  Any help would be appreciated. 

While I am at it, how could I set it up to get the Bayer encoded image.  All the examples I have seen the images look like they are black and white.  Is there a way to configure the grab to be baye encoded?

Hello Matt,

Could you provide some more detail about this error

- What version of LabVIEW are you using?

- Which version of Vision software are you using?

- Is there an error code associated with this message and what is the exact wording on the error message?

- A brief description of the VI's you are using or applicable details about your code would be helpful too.

Thanks,

Anna K.

I figured out the issue with the property node, but the second question is really the one I need help with. 

     The camera manual says that it uses bayer encoding and I want to set up an automatic white balance using labview.  From all the stuff I read on the posts, the only way to do it besides property nodes, which is kind of useless since each time a correction needs to be made, the session has to be closed and a new one opened with the new rgb gain values, is to use the bayer encoded vi along with the bayer LUT vi.  Now the problem is, how can i take the feed from the camera and make it a bayer coded image?  when i try to wire it to the vi, it gives me a runtime error saying incompatible image.  Can you please help me with this?  I looked on the options in the property node and saw none.  I also looked for some kind of a clue in MAX but nothing stood out.  There a post with an example but it doesn't use a camera input it uses a file, so that didn't help much.  My specs are below.

JAI cv-a70ge camera

labview 8.2.1

VAS 860and VDM 850

The Jai uses a gigE ethernet to connect to computer.  

Thank you

Matt,

I went to the NI Example Finder and typed in the search keyword - Bayer - and found 4 examples of Bayer decoding with snap, grab and ring. Did those not help?

A Bayer image is going to come in as a greyscale image and then must be decoded according to the camera specs.
