This sample project shows how to use the v15 .NET libraries in C# 2.0 to:

1.
Declare and use Windows API functions to create a System.Drawing.Image object

2.
Create a new RasterImage from a System.Drawing.Image.

Here's a version of the same demo that uses only the LEADTOOLS SDK rather than low level Windows API function declarations.

It uses the ScreenCaptureEngine.CaptureFullScreen and then the CropCommand to crop the image to the desired size.

I've updated this project to use the LEADTOOLS v17.5 in C# using Visual Studio 2008. This project uses the ScreenCaptureEngine.CaptureFullScreen and then the CropCommand to crop the image to the desired size.
