Difference between System.Drawing.Bitmap and System.Windows.Media.Imaging.WriteableBitmap

Question

What is the difference between the 2? Some examples would be great!

Answer 1

There is no System.Drawing.Bitmap in Silverlight.

If you are asking for a comparison between this in the .NET framework and WritableBitmap in Silverlight then the differences are huge. The WritableBitmap is a simple representation of a bitmap with very few constructors or means of manipulation. Most of what you can do with Bitmap you would need to implement yourself via the Pixels array.

Answer 2

The most powerful aspect of WritableBitmap is the Render() method which allows rendering a UIElement atop the bitmap. This can be used to transform images (scale, etc.) or to render overlays, etc.
