Ok, I got the magic wand to work. I need to grab the byte array that is the region and then save that off to an object. I have tried the following

Dim test As RegionData = RasterImageViewer1.Region.GetRegionData()
test does not instantiate and the lead tools error tells me to use the new keyword
If I use the new keyword then i get the following error

Type 'System.Drawing.Drawing2D.RegionData' has no constructors.

If I use the code from the documentation as follows then I get another error.
Dim data() As Byte = RasterImageViewer1.Region.GetRegionData()
I get the following
Value of type 'System.Drawing.Drawing2D.RegionData' cannot be converted to '1-dimensional array of Byte'.

So what steps do I take to get the regiondata for this region. I see that IRasterImage.GetRegionData() uses RasterRegionXForm as a parameter but can't find in the documentation how to use this object.

If someone can point me to a sample app or where in the documentation to look I can take it from there.

Thanks, JC

JC,
Before I go into the details of the question, I want to make sure you're searching in the right direction.
Do you want to get the coordinates of the region, or the image contents (pixels) within the region?
I'm asking because the GetRegionData method gives you the coordinates of the region, not the bitmap contents.

I need to get the coords of the region. Don't care about what is there, just the coords.

JC,
I think I found the problem.
You seem to be using RasterImageViewer1.Region.GetRegionData(), which is inherited from the System.Windows.Forms.Control class.

The function you need is RasterImageViewer1.Image.GetRegionData, which is the LEADTOOLS region data function.
