The purpose of this open source project is to provide a basic template for a Photo Effect Editor in UWP that takes advantage of Win2D’s capability for processing images very rapidly using GPU and video memory.

Learners of Win2D can make use of this application to visualize and explore the various parameters provided by each effect in Win2D. A programmer looking into writing a photo effects editor will not need to start from scratch. This project may be used as a basic template that can be extended further with more effects and features (such as text overlays) to make it a full fledge product.
