AxCWIMAQViewer.ControlImage question

[Pratt]

I am trying to use the AxCWIMAQViewer.ControlImage() method (Vision 8.6, C#) to extract a currently displayed image for saving to a file. The image after extraction has a very large pixel size (image.Width, image.Height) which is greater than the original data or the screen size. My first question is where is this resolution coming from? The second thing I am seeing is edges of different shades of gray surrounding the image (frame borders?). I would like to extract only the data and not the background around the data or the borders of the control. I have been trying to extract the rectangular region of the data by finding the transition of the image and the actual data, but I am finding multiple shades of grays and blacks and they are not the same on any of the sides. Once you get the image is there a way to then extract only the actual data and not the blackground, borders and/or what ever else is in the image surrounding the data?
