In this next post René Schulte has extended the WriteableBitmap with some specialized methods for various shapes including a fast ellipse rasterization algorithm.Image

Last week I've released the second part of my WriteableBitmap extensions methods. I've added DrawLine() methods and presented a sample application that showed that the WriteableBitmap line-drawing methods are 20-30 times faster than the UIElement Line class.

A stable and fast line-drawing algorithm is the basis for most shapes like triangles, rectangles or polylines in general.
