Error message: incompatible image size when using IMAQ in image processing

[Riq]

I want to do low pass filter and convolution on an acquired image. When I connect the image to the VI, the message: incompatible image size appears. I have tried to set the border to 3 in IMAQ create, but it does not help. Anyone know how to solve this problem?

A couple things might be causing this problem-

1) The convolution matrix is bigger than 7x7, or

2) You have created an image, but there is not yet anything in the buffer

You can check number 2 by doing a winDraw window just before you do the convolution.
