The goal of this project is to create an open source light weight screen capturing Framework for Windows based applications. Supports the following:
Some times we want to capture the contents of the entire screen programmatically. This library helps achieve it. The article at http://www.geocities.com/krishnapg/screencap.html explains how this library works and how you can use it in your own applications.
Typically for screen capturing, the immediate options you have, among others, are Using GDI and/or DirectX. Another option that is worth considering is Windows Media API. For best performance, GDI is the way to go. But when you want to add further options like distributing the captured content to multiple audience over network, then Windows Media API offers good collection of classes to achieve it easily.
Optionally, with GDI approach or DirectX approach, once you get a sequence of screen shots, you can then process them further to generate a movie for offline viewing.
Refer to the article Create Movie From HBitmap for more details about creating movies from bitmap sequences, or to the article Simulation Recording for details on a simulation recording library for windows.
In the download section, you will have the option to download sample applications demonstrating the use of capturing the screen content using the three approaches above mentioned, namely GDI, DirectX and Windows Media Encoder.
