Get front panel image

I want to print the front panel image with a specific resolution independent
of the actual size of the front panel.
I had the following idea: I use a prperty node with "get front panel image"
feed an intensity graph in a sub-VI with the information and print the panel
of the sub-VI. The intesity graph of the sub-VI has always the resolution I
need for the printer.
This works fine. The peoblem I have is that I can not use the property node
with 24 image depth. For the colour table (I need it for the graph) I always
receive an array with the size of 256 as I receive it with 8 image depth.
With 24 image depth I should receive a much longer colour table.
Maybe somebody has another idea to print the front panel with always the
exact res
olution. Independent of the panel size - always the exact similar
picture on the paper.

I've played with this some myself. Apparently, LabVIEW can only use up to a 8 bit depth or 256 colors for this function. Most of the time, that is sufficient for printing images which are usually in grey scale anyway. You might also want to play around with some of the Print Methods using invoke nodes. You can print to an html doc and specify whether you want a JPG or PNG and the color depth for the image. You might be able to take advantage of this to work around odd printing problems.

Problem with Append Front Panel Image To Report.vi

I'm using LV 7.0 with the MicroSoft Report Generation toolkit installed. Under the Report Generation palette there exists an Append Front Panel Image To Report vi. Also on the same palette there is an Easy Print VI Panel or Documentation.vi which uses another Append Front Panel Image To Report vi located under the VI Documentation subpalette. Here is the problem; I have serval vi's that use Append Front Panel Image To Report.vi from the Report Generation palette and I have a couple of vi's that use the Easy Print VI Panel or Documentation.vi which is linked to the Append Front Panel Image To Report.vi located under the VI Documentation subpalette. Clear as mud!
This creates a conflict of intrest. In a nut shell th
ere are two vi's with the same name in different locations doing different things. I have a program with subvi's that need to call each respective Append Front Panel Image To Report.vi and that just is not working.
Is this a known issue with LV7.0 that has already been addressed and/or resloved?
Thanks.

ATC Herman,
Based on the picture you posted and what you are describing, it looks like you might have an incomplete install. What version of the toolkit do you have? Was it first installed on an earlier version of LabVIEW, or did you install it first on 7.0? Your VI Documentation Palette appears the same as if you hadn�t installed the toolkit. I�ve attached a screenshot of what it should look like. The VI in question is a polymorphic VI, which may be causing some of the confusion. If you right-click on it and select �Open Polymorphic VI�, it will show you what options you have, depending on the input. I opened both test and test1, and they appeared the same for me. I was able to have them both on the block diagram. The path to bo
th of them was C:\Program Files\National Instruments\LabVIEW 7.0\vi.lib\printing\ReportDocExtensions.llb\Append Front Panel Image to Report.vi. The .llb ReportDocExtensions has the polymorphic VI, as well as copies of each of the possible instantiations. Make sure you have these VI�s in the .llb in that directory.
There is a KB on having the toolkit on multiple versions of LabVIEW and what files you need. Make sure you have all the files listed.
Please let me know if you are able to get to the bottom of the issue with the above information.
Thanks, and have a happy day!

Append front panel image to report

I am using Labview V6.1 on a Win2000 PC 2.4 Ghz, 512MB RAM.
I am trying to use the append front panel image to report VI to append a VI panel image to a report. I am using notifiers to synch the execution of the VI with the desired front panel an the report generation process. I keep getting an error fron the Append VI that is a 1004 which is VI not in memory. How do I keep a vi in memory? I thought it would stay in memory as it is waiting for a notification from my report section for completion before closing. The notification stuff seems to work properly. Any ideas?

Here is a VI that demonstrates the problem I am having. The other VI is the VI I am trying to append to the report.
Let me know your thoughts. I will be away from this forum starting 8-27 til 9-1.
Let me know your thoughts.
put these files in a c:\P368 folder. or edit my VIs

Save sub-vi's (possibly closed) front panel image to a file

Hello,
I would like to dump a file of a sub-vi's front panel when that sub-vi completes execution. I was thinking of using the "Front Panel:Get Image Method", however the target sub vi's front panel might not be opened. I am looking through the help file, and it says
"If you do not want to display the front panel but want the image to reflect value changes, create a Property Node from any front panel terminal on the block diagram of the VI for which you want to create a front panel image."
I'm not quite sure I understand what that means. Can anyone provide an example?
I am running LV 8.2 for the record.
Thanks,
-Ted

Hi Ted,
"If you do not
want to display the front panel but want the image to reflect value
changes, create a Property Node from any front panel terminal on the
block diagram of the VI for which you want to create a front panel
image."
What that means is to create a property node for something (anything) in your Sub-VI.
I have attached an example for you with a dummy property node. And the front panel of the Sub-VI gets updated on the Main-VI. Try removing the property node in the Sub-VI and you will notice that even though the values are correct in the main-vi, the image of the sub-vi doesn't get updated.
Hope this helps!
Warm regards,

How can I save an EXE front panel image to a file?

The methods to save a VI front panel image to a file don't work on executable applications. How can I save an EXE front panel image to a file? (LabVIEW 6.1)

Hi,
i wrote some vi that save FP to image and created exe and it works fine. How do you save FP to image in VI?
If you use VI server method "Get Panel Image" and use "Write JPG file" ( or BPM) it works fine.

New report page and append front panel image

Hi,
I am trying to create a report using the Report Generation toolkit in LabView 6.1 which gets printed to PDFCreator.
I have 4 front panel images that I am appending to the report, and I would like each image to be on its own page. I am trying to accomplish this using the New Report Page vi, but it doesn't appear as though it is putting any page breaks in the report, and no errors are being generated. Do the page breaks that this vi puts in only apply to text? What is another method that can accomplish putting each image on its own page? Simply creating and printing 4 reports will not work, since I need the 4 images to be in the same PDF file, and PDFCreator does not support appending to PDF files instead of overwriting.
Thanks,
Ian

Hi Ian,
According to the Help for "New Report Page.vi" you can append either text or another file to the new page. Are you creating a standard report?

Printed front panel graphics quality (Print Panel to Printer method vs. Append Front Panel Image to Report.vi)

LV 6.02 (or 6.1)
NT 4.0
I have a vi that the front panel includes all the information I need to print except that it is on different pages of a tab control to conserve screen space. I was attempting to programatically cycle the value of the tab control in a For loop and invoke the Print Panel to Printer method to print 7 pages of the front panel, each with a different tab page selected. The printouts were excellent quality but beginning with the second consecutive Print Panel to Printer method the on screen front panel image of the VI being printed would become jumbled (sometimes, by the time 7 printings were done, the entire front panel image would disappe
ar and a bitmap of the desktop or underlying windows would be visible in the VI's panel frame) yet the subsequent Print Panel to Printer methods continued to print the panel as they should appear. The visible front panel graphics would never return to normal and the only solution was to close the vi (in the dev system) or exe (compiled) and re-launch. I tried a lot of things (like hiding the panel to print before printing and showing it after printing) with no luck. It appears that two or more of these consecutive invoke methods caused the problem regardless of whether the tabs were cycling, or even if there was no tab control and much fewer controls on the panel to be printed than normal. I also had the same problem with LV 6.1.
Finally, I was forced to switch to the report generation toolkit vi's, I cycle through the tab pages and use the Append Front Panel Image to Report.vi to append each image to the report. This is faster and control returns to my program quicker but I a
m unhappy with the printed quality of the graphics of the front panels. They are not as high of resolution as those generated via the Print Panel to Printer method.
Any suggestions?

You might try changing the way the VI is printed by going to tools >> options >> printing. Try the postscript and bitmap settings.

Append front panel image crashes in 7.0

I'm trying to use append front panel image.vi in
Labview 7.0 and when called Labview crashes in the
standard report case calling invoke node for IReportData > AppendPictureFromFile. Labview just
quits. What's weird is it appears to work on a
system w/ a local printer but not one w/ a network
priner. Any ideas?

try to generate an HTML report first, and then print that. Some printers are worse than other at printing (what looks like) a simple object.
Otherwise, I would do some basic trouble shooting, like can you print a simpler front panel image (say two numerics) to the printer. Next, I would try to print to a different networked printer.

TDMS Low level file functions and Saving Front Panel image

Am using TDMS low level file functions to save while also plotting data in my data acquisition programme. However, I also want to programmatically be saving the front panel image on every run of my data acquisition. I have coded all other aspects, except the behavior of functionality of saving the front panel image on every successive runs of the application. Unfortunately, I just have no idea on how to code this aspect on LabVIEW, and all effort to search for example codes on so far have not been successful.
I would appreciate any useful hints or steps from anyone for me to follow, in order to accomplish this behavior, and that is being able to programmatically save my front panel images while using TDMS low level file functions in my File IO system of my application.
Thanks in advance.

How to get front panel sou

how to get front panel sound for me headphones, i have audigy 2 ZS.

Works Great. Thanks
!!! Although .... the gain on the front mic is very low compared to the rear mic jack. Instead of using the x0 pin plug for the mic, I configured/spliced the front mic wires into a (rear) pass through /8" jack lead. Now, the front panel mic is at full output. I lose the?rear mic input, but I'll never use it now that I have front panel input.

Save a front panel image problem

Hi, i'm trying to save at run-time an image of my front panel, and the little code with the Invoke Node (FP.GetImage) works well but there is a problem, i have a background image for my front panel and this image don't show up in the image saved so i have an image with controls and graphs but a blank background. Is there some way to obtain an image of my ENTIRE front panel? Thanks

Hi,
Here's how I got ride of tghis issue, I use Windows "printscreen" function by simulating a keyboard stroke and then I get the data from clipboard (crop it it necessary) and save the image.
What I like about it is that the "crop" makes it easy to get just what I want when there's more than one monitor.
What I don't like is that it's a windows only solution.
Hope it helps

How can I save front panel images each time a loop iterates

So I've been working on some optical codes in LabVIEW for a while, I've read a lot of these similar questions but I can't seem to apply them directly to my situation in all cases.
I essentially have a code that shows an intensity graph that is continually modified in a for loop, I want to save a picture of that intensity graph each loop without having to manually label them. Is there something similar to the get image node that can do this. I've looked through the image acquisition in the vision VIs but only see references to hardware like cameras.
Attached is a simplified version of a changing intensity graph. With the get image I have to establish the names of 10 images and the path there before it will run and save like I want it to.
A million thanks to anyone who can help

Sample image save.vi ‏19 KB

That worked wonderfully and is exactly what I need for the phase diagrams Im working with. I have a new and similar issue, I do have a camera showing us our laser source in a CCD image within my code. I was hoping to get a picture of that each iteration and hoped the solution you provided would work for both but the CCD jpgs are just black. I'm assuming I may have to use a different acquiring technique with that but dont know the best way to go.
Any help there? I cant really post a VI since the camera stuff wouldnt work but heres a screen shot of the front panel and the CCD image that id like to capture.

Get front panel position of the control strange behavior

Hi,
I have a code that returns the front panel coordinates of a control. I use the same code and front panel design (splitter/pane layout) in two separate VIs, but I get two different result in each VI and I cannot find the difference between them. VIs are attached. I have LV2013 f2.

Dear Andrej,
you are indeed correct. If you happen to have multiple panels with splitters, the you have to account for the splitter positions as well, assuming they are to the left, or on top of your control. Here's some very simple code written for your example:
Of course to make it more flexible for any setup, you will need to add some tuning to that (you can programmatically get the right pane instead indexing with Owning property, check splitter Vertical? property to decide which coordinate to add to, check whether to include splitter based on position and other things I've been too lazy to properly code ), but this is the basic idea.
Kind regards:

Printing front panel images of subvis from executables

I have a top level vi which calls a subvi which has all the plots I want to print in a report. This works as a vi as I can reference the subvi that I want to print the image of. When I make it an executable it no longer works, and even if I change the reference to request the image of the toplevel vi, so that there is a clearly viable (.exe) reference to print, it does not work. I can use file print window, but this does not give me the report. only the image. Any advice gratefully received
Solved!
Go to Solution.

We need to see your code to be sure, but I'm guessing you are getting the VI reference using the path to the VI. Well when an EXE is made the path to the VI will not be the same. You should use a Static VI reference to get a reference to the VI, and then the location on disk doesn't matter.
Here is a quick example I did a while ago using replacing VITs in a similar way.
