Remarks

Use the WriteableBitmap class to update and render a bitmap on a per-frame basis. This is useful for generating algorithmic content, such as a fractal image, and for data visualization, such as a music visualizer.

The WriteableBitmap class uses two buffers. The back buffer is allocated in system memory and accumulates content that is not currently displayed. The front buffer is allocated in system memory and contains the content that is currently displayed. The rendering system copies the front buffer to video memory for display.

Two threads use these buffers. The user interface (UI) thread generates the UI but does not present it to the screen. The UI thread responds to user input, timers, and other events. An application can have multiple UI threads. The render thread composes and renders changes from the UI thread. There is only one render thread per application.

The UI thread writes content to the back buffer. The render thread reads content from the front buffer and copies it to video memory. Changes to the back buffer are tracked with changed rectangular regions.

Call one of the WritePixels overloads to update and display content in the back buffer automatically.

For greater control over updates, and for multi-threaded access to the back buffer, use the following workflow.

  1. Call the Lock method to reserve the back buffer for updates.

  2. Obtain a pointer to the back buffer by accessing the BackBuffer property.

  3. Write changes to the back buffer. Other threads may write changes to the back buffer when the WriteableBitmap is locked.

  4. Call the AddDirtyRect method to indicate areas that have changed.

  5. Call the Unlock method to release the back buffer and allow presentation to the screen.

When updates are sent to the rendering thread, the rendering thread copies the changed rectangles from the back buffer to the front buffer. The rendering system controls this exchange to avoid deadlocks and redraw artifacts, such as "tearing".
