using .net GDI functions in labview

[david_jenkinson]

Hi,

I want to find out if I can do an image operation, using .net "GDI", which I've been told contains a gaussian blur function, which I want to perform.  I am familiar with activex usage in labview, properties/methods etc, and have used that quite a bit.  In browsing around the .net palette, there appears to be similar "property" and "methods", and an additional "constructor".  It appears I can choose from libraries, similar to activex.  But I do not see a "GDI" or image related library.  Does anyone know how to get at image related functions in .net?  Also, I was trying to find some examples of .net usage in the labview examples, but couldn't find any.  Are there any examples there or elsewhere that I may be missing?  

Thanks

Dave

There are a couple of .NET examples that ship with LabVIEW. If you open the Example Finder and search for .NET you'll find 4 examples. Not many, grant you. As for your specific question, when you plop down the constructor you have to select the appropriate .NET assembly. A lot of the classes are in the "mscorlib" assembly that is in the list, though in your case you probably want the System.Drawing namespace. Your best bet is to find a working .NET example (such as this one) and that will tell you the steps you need to perform.

Addendum: You may also want to consider the image functions in LabVIEW, such as the stuff available in the Vision Toolkit.

Thanks,

I did find those examples now.

We do have the vision development module, but there is no blur function.

Actually, in case this post leads anyone astray, there IS the ability to blur using NI vision functions.  It is using the "IMAQ Convolute" filter.  I stumbled across this using vision assistant.
