Testing WriteableBitmap's realtime capabilities

WpfRealTimeBitmap

Demo to test WPF's WriteableBitmap's realtime capabilities

This application creates a backing image ColorScaleImage with randomized values scaled from 0 to 1. These values are translated into greyscale as they are mapped to WPF's WriteableBitmap which can be directly shown on screen. This process is repeated for every frame up to WPF's default limit of 60 fps.

Major concepts demonstrated

• Convert a custom image type to a WriteableBitmap so it can be displayed
• Efficiently use pointers to move data into WriteableBitmap
• Parallelize the conversion process
• Use CompositionTarget.Rendering to improve render timing compared to DispatcherTimer
