In Windows Store app, you can't use GDI/GDI+ graphics API any more. This sample will show you how to draw watermark text or image to a bitmap in D2D. The sample contains two projects: one is a C++ Windows Runtime Component which wraps D2D/DWrite/WIC API and exposes some drawing functions and helper functions; the other one is the Client app which consumes the WinRT Component to finish the real work.
You can find more code samples that demonstrate the most typical programming scenarios by using Microsoft All-In-One Code Framework Sample Browser or Sample Browser Visual Studio extension. They give you the flexibility to search samples, download samples on demand, manage the downloaded samples in a centralized place, and automatically be notified about sample updates. If it is the first time that you hear about Microsoft All-In-One Code Framework, please watch the introduction video on Microsoft Showcase, or read the introduction on our homepage http://1code.codeplex.com/.
