Hi there!

I am looking for a possibility to draw e.g. a circle or rectangle with some
text in it (VB.NET and GDI+). The text will be moving, but must never exceed
the edges of the circle/rectangle. So the text should be "cut off" at the
edges of the surrounding circle/rectangle.

Can anyone give me some hints how to achieve this? Would really appreciate
any help!

Thanks in advance!
Phil

Use the drawing2d.GraphicsPath class to draw the shape. Apply a
region to the graphics object using the GraphicsPath to clip the
output eg

//not tested

graphics.DrawRectangle(new Rectangle(500,500,100,60));

graphics.Clip = new Region(graphicsPath);

graphics.DrawString("hello world"); //more parameter options here

Thanks again for your help!!

One more question: how can I now draw other things outside of this "clipped"
area? It seems that once I use "graphics.clip" I am unable to draw other
things around this previously drawn clipped object...

Would (once more) appreciate any hints! ;-)

Thanks!

Hi,

You need to reset the clip - graphics.ResetClip should do the trick

James could you give a more detailed example in VB.NET? I'm trying to make a
simple windows app that places text within a circle.
