.net image editor management

I am looking for a .net control that allows me to edit images. The following functions are desirable:

• Crop
• Click to enlarge
• Pen
• Line
• Brush
• a circle
• Polygon
• Complete undo / redo
• Measurement tool
• Layers (not critical)

This control can be Winforms or WPF, but must be extensible.

I am happy that this is commercial control or open source. If source code is also available, C # is required.
