bug in IMAQ GetKernel family type enumeration

[Root_Canal]

Your kernel filter family enumeration type for IMAQ GetKernel contains an item that crashes the function when selected.

To see this irritating bug,

1)      place IMAQ GetKernel on the block diagram

2)      right click on the Kernel Family input node

3)      create a control

Notice that the enumerated type that you have programmed into IMAQ GetKernel contains a blank value for the number zero. This value breaks IMAQ GetKernel. What’s worse, IMAQ GetKernel requires this broken type, so if you create a control that doesn’t break IMAQ GetKernel, you have to cast it to a broken type on the block diagram to use it, then increment the value to make it correct.

 

Furthermore, the default control for the kernel size input node correctly coerces the minimum value to 3 and sets the increment to 2, but inexplicably allows a maximum value of  (2^32)-1.The maximum allowable value is 7, beyond which GetKernel will once again break.
