FormShaper is a .NET component that can change the form to any non-rectangle shape in very simple steps.

You do not need to write a single line of code, instead, what you need to do is just clicking some properties by mouse. It is so easy to to get a REAL non-rectangle Form in seconds.

FormShaper is 100% native .NET framework managed components written in C#. The shape of the Form is determined by a bitmap and a transparent color, by which the color is used to scan the outline boundary. If detecting by Spy++, you will find that the Form's window was really changed to non-rectangle shape. This is different to setting the TransparencyKey property of the Form.
