Problem for linking IMAQ 2D FFT

[pil]

Hello,

I would like to use IMAQ 2D-FFT VI's to make High-pass filtering, but just can't get the conversion VI ("FFT") working.
It always gives me the same message:
"IMAQ FFT source and destinations must be different"
If somebody has just a small source to show me how to make an image file High(or Low) pass filtering using IMAQ features, it would help me to understand how to plug it...

Thanks in advance for help.
(I join a file which shows typically what I do not understand: how to plug the VI FFT)

Hello Jean-Philippe,

To use this FFT function the Image Dst needs to be a complex image and the Image Source for the FFT-1 needs to be a complex image as well. I have attached a VI that uses this FFT function which should shed some light on the issue. Hope this helps. Have a good one.

OK, I get the point,
I gave it some other tries, but always forgot ot precise the complex type for the new image st I was creating...
Thanks for the help Dan,
