How to build 2d filters?

Is there any simple way to build 2d filters. LabVIEW has a lot of 1d filters but I could not find any 2d filter. It is possible to design a 2d filter by taking the subset of the 2d array and processing it, but it takes a lot of effort. Is there any quick way?

Not so much effort in fact.
I do it with 2D convolution (http://dynabits.com/labview/libview.htm)
