I believe you and I spoke about this in chat regarding calculating HU values. Getting the pixel intensity is the first step in calculating HU and the demo on http://support.leadtools...rums/24633/ShowPost.aspx shows how to get the pixel intensity.

Keep in mind that this is just s simple demo and doesn't cover all the bases. It is your responsibility to understand how integer values are represented in binary and how to properly convert the binary data returned from GetPixelData into an integer.
