FP Get Image Invoke Method Problem

[jon_mcbee]

I am having trouble with the Invoke Method FP Get Image (I discovered the problem by trying to use the Report Generation Toolkit -> Append Front Panel Image to Report.vi).  I am trying take an image of the entire Front Panel (not just visible) and write it to a word report.  I have software that did this beautifully in LV 8.2.1, but I recently upgraded it to 8.5.1 and it no longer works correctly.  I have attached an image to illustrate the problem.  You can see that most of the front panel exists in the image, but I have an array of XY graphs that only exists as seen on the visible front panel.  I have tried explicitly setting the option to image the entire front panel with the same results.  I dont understand how the other parts of the front panel (the numbers for each graph exist as a table of strings and are overlayed ontop of the graph, there is also a summary graph on the bottom left as well as some text on the bottom right; all of this shows up even though it is not on the visible front panel).  If anyone has seen this or something similar I would love to hear how you handled it.

Thanks!

I have seen similar issues (non-visable object images) on and off through various version of LV and its getting better.

Work-arounds I'd try are;

1) Do an invoke node get image (make sure you use an element of the returned output cluster to enusre LV does not optimize it out) on the object that is not showing.

2) Defer.FP.Updat T/F since a the defer forces an updated (since 6.1?).

3) Hide/show object that needs refreshed.

So anything that effectively "jiggles the handle" has worked in most situations.

If these don't help please post a dumbed down example that demos this so an AE can confirm and file a CAR.

Hello Ben,

I appreciate your help.  I tried to jiggle the proverbial handle with no luck.  I am going to work on a simplified version of my problem so that I can post it.

Thanks!

Alright.  Attached is a simplified version of the issue I am having.  I have contacted NI via phone support and an AE is working on it.  However I am open to any suggested fixes or workarounds as I need to get this software back up.  Please feel free to ask any questions.

Thanks

Hello.  I have built a simplified version of the software that shows the problem I am having.  Please feel free to take a look and make suggestions for either a fix or workaround.  I have been in touch with an AE via phone support so NI knows about and is working on this problem.

Thanks!

I apologize for the double post, having some internet issues at work and I didnt think the previous post had been sent.

Hi Jmcbee,

We tested this out at NI and this is a CAR. We are in the process of filing the CAR and I will update you with the  CAR number when it is done. Thank you for feedback on this! Its truly appreciated.

SubVI missing.

[jon_mcbee]

My apologies.  See the missing Sub VI attached below.

Hi Jmcbee,

I was able to replicate the problem without the sub-vi since we just created our own example. The CAR ID is 117602.

By resize the front panel and/or force redraw, I was able to capture the whole front panel.  See attached zip file.
