Commercial drawing component???

[Hakan Andersson]

Hi!

I'm a system designer/programmer starting up a new project where we
want to be able to let the end user create graphic pictures.

The application will be web-based using C#. The drawing-area need to
have a bitmap as a background and on that bitmap, the user should be
able to put/create approx. 10 different custom-made objects.
Objects should not be resized. Some should be possible to rotate and
some not. Custom lines with arrows on the end should be able to be
placed on the graph also. They could be attached to an object, but do
not need to be. If they are, they should be automatically moved when
the object is moved. Some of the lines are not just a straight line,
but have a sig-saw shape. These sig-saw lines should be able to extend
without the sig-saw shape being extedned like a accordion.
It must be possible to present a sub-set of all controls to the end
user so that the the user does not see more controls than he/she have
to.

Can anyone please suggest a commecial component that can do all this?

All the best /Hakan Andersson
