Read MatrixCode using .NET or dll

[LuisMontoya]

Hello.

I'm trying to decode a Picture (get it from WebCam) matrix code using the .net module in labview ???

I'm using LabView, but the licence for vision package is too expensive and I'm going to put this Sequence in 4 testers.

At this time, I already have the VI to get the Picture from any USB-WebCam using AForge .net library

I can provide the Picture as a file or an array of numbers (24-bit pixmap from "Unflatten Pixmap" VI in Labview .

I annexed a picture taken from one of the USB-Cameras

Thank you!

Do any body has a diffrent .dll, .net, or VI to decode MatrixCode for free? (without Vision system.)

Hello Luis,

Thanks for using the NI forums! There are several 3rd party programs that you can use for that purpose only that supports ActiveX (DataMatrix, Moda Barcode Reader). But some of them aren't free either, if your purpose in the near future is to decode matrix bar codes only its ok to use these kind of software and call them via ActiveX within LabVIEW but if you plan to develop more complex projects and applications that involve vision and analysis then I strongly recommend you the Vision Module, its more cost - benefit and it will allow you to focus in you real target and spend less time in software development.

Hope you find this information useful!

Thank you, 

I'm going to use just to read Matrix and Bar code (still we can use scanners), the cost to use Vision Modelue is too high to use it just for this,

I been evaluating to buy the Vision Run time but it's to expensive for all my machines (unless 6 stations for now), 

I already have the Vsion Development package, 

Thank you

DataMatrix Decode Done!!!

Using Freeware DLLs...

PD, Need to Download and Install "AForge.NET Framework-2.2.5.exe" before run the VI's.

Does the barcode reader you mentioned is free to use program? If not, do you have any suggestion for a free .net barcode recognition dll?

[LuisMontoya]

Yes it is free...

This freeware dll only support DataMatrix, other 2d barcodes is not supported?

to decode the picture, VI is using the Zxing.dll, you can modify the of decode if double click the "BarcodeReader" Constructor, there is many options (one is "MultiFormatReader")

you can go zxing.org to get the latest version and maybe you can find more information.

I just make this because I'm using just 2D codes.
