When I delete virtual folder in me project this results in a LabVIEW crash. This happens in windows 10 and in windows 7, even if I have a project with only empty virtual folders and I start deleting them.
Are there other people where this is happening too?
I need one help regarding changing the image image type
How can I convert grey scale image to false color image?
Here, I have attached two images. 1. greyscale image 2. is just an example that I want to convert. (False Color).
Any help would be appreciate.
Understandably NI's own line of analog video frame grabbers have been obsolete for some time (since 2010 I believe).
I have an industrial application where I am bound to using legacy analog VGA cameras. Upgrading the cameras is not an option
I would like to use LabVIEW for testing purposes. Are there any good non-NI frame grabbers still out there that are easy to get up and running with LabVIEW?
Unfortunately due to the bureaucratic purchasing processes ordering an old NI card of e-bay is not really feasible.
So, I've installed LabVIEW 2017 and I'm starting to play around with it. Malleable VIs are cool! (No more giant OpenG toolkits where there are 10 instances of the same VI for multiple datatypes.)
Another cool thing that I've observed is that the example "sort 2D Array" function can support a scalar and an array input for index. Upon further digging, there appears to be an interesting disable structure that intelligently selects the upstream input that yields non-broken code.
Does anyone have more information about this structure? Is this related to the experimental structure that Hooovah talked about in his Xnodes presentation at NI week? I'm just curious if this is stable... and if I can start using it... and it there is any documentation on it that would tell me how to use it.

In the attached image I have four Code 128 and two Code 39. I have problem detecting them without down sampling the image first. Since I want to grade the bar codes I don't want to down sample since the code quality is reduced then. I noticed this from that sometimes some of the bar codes are found without down sampling an then the grade is higher for those. Down sampling a factor 2 sometimes work, down sampling a factor 4 always works.
I have tried croping the image around the bar code but this doesn't help.
I'm using IMAQ Read Barcode 2, and have tried to change the parameter Min Bar Width with no result. Is there any other parameter I can change for the algorithm to find the barcodes, without having to down sample my image.
