imaqMorphology problem

[yaHeard]

Hello,

It seems as though this is a known issue with CVI 8.5 and has been reported to R&D (# 43519).  At this time, I could not find a possible workaround other than placing NULL as the element, but I assure you that our R&D department has/is investing time on this issue.  Thank you for the heads up and you can look for the reference number 43519 in future releases.

Thanks Carlton,

I'll keep my eye out for a fix.  In the meantime, is it fine to use the function without the structuring element set to NULL in release mode, and if so, does it work properly in release mode or does it use the default case the same as if NULL were used?

Hello,

I wrote a few VIs that compared the original images with a couple of different builds that performed the ImaqMorphology function in CVI 8.5 and it looks like using the structuring element in a release build produces the same results as using NULL.

Hello,

I'm developping an application using image processing. I set up the image processing method with NI Vision Assistant and generated the C code for Labwindows CVI. Yet I face the same problem, that is to say, as soon as I specify a structuring element in imaqMorphology function, there is the run time error:

Out-of-bounds pointer argument (past end memory block)

My configuration is:

Windows 2000 SP4
Intel Pentium 4 3.6GHz
NI Vision Assitant 8.5.0
NI Labwindows CVI 8.5.0

Thanks.

Hello JS,

This is a known issue with CVI 8.5 and has been reported to R&D.  As a workaround you will need to use NULL as the structuring element.  The reference number for this issue is 43519 so you can check for it in the upcoming releases.

Is there a timeframe available on when an update that fixes this issue?

Hello,

As Carlton mentioned, this is a known issue and will be corrected in a future version of CVI. Unfortunately the specific details of a release date are not yet available. Until the fix is implemented in a future version, continue using the NULL workaround mentioned above. Happy programming 🙂
