I have looked at this function and could not find it as you already mentioned. I believe there is a loop running on Vision Assistant, which tries values and suggests fastest parameters. So, if someone share the algorithm behind that, we can create such a function.

Here is some code that can be used to suggest datamatrix parameters, similar to what Vision Assistant is doing behind the suggest values button. I am attaching a zip file that contains 2 VIs. The main VI you want to use is "Data Matrix Suggest Values.vi".
Hope this helps. Let me know if that works for you.

Hi Christophe,
I came across your VI posted for Data matrix suggest values. But I am getting an error constantly when I pass my image and ROI.
Error -1074395635 occurred at IMAQ Read Data Matrix Barcode 2m
IMAQ Vision: The passed shape descriptor is invalid.
the ROI being passed is a rectangle. I have 34 barcodes in a single image and trying to decode them all.
I need a solution for this very badly. Appreciate your help!!

Hi, I just got this error like you when I tried to inspect a DataMatrix Code: the passed shape descriptor is invalid.
On the Barcode Size Option, I reduced the minimum size of the bacode to 0 and the maximum to 1000.
Good luck
