To get the points on the perimeter of a Rounded Rectangle

[rashibahal]

Hi all
For some requirement in my project i have made a Rounded Rectangle. Now i want to know how can i calculate to get the points on the perimeter of that rounded rectangle.
I also have a point of reference which will be helpful to get the perimeter points.
Plz help me as its very urgent.

Thanks in advance

How did you accomplish the Rectangle? That should have the data for the rectangle already.

[rashibahal]

No it does not provide the data to calculate the perimeter. I want to know if some algo or code is available for this. I am using it in a method which does not provide any of the helpful functions. I have to calculate it myself.

Jordan says that, to draw a rectangle you need data, basically coordinates. You say that you don't have those?

[rashibahal]

Ok, i misunderstood wht he said. I have the bounds of the figure i.e. the rounded rectangle, which gives me the height, width and the location of that rounded rectangle.

Now you know a fixed location(is that center coordination of the figure?), width and height. Just you want to find the radius of curves, right?

Seems to me you need a simple functionality find the curve length.

No, its not so...let me tell u the whole scene.

I have a Rectangle of draw2d.geometry...which is passed in the graphics.drawRoundedRectangle() method...Hence i get a rounded rectangle figure.
Now, in some other class i am using an overriden method... i get the access of that same draw2d's Rectangle which i used to pass in the drawRoundedRectangle()..but in the present class i am using an overriden method and i dnt have the graphics object available.

Now, using that Rectangle...i want to make a method that would get the point exactly on the edge of the rounded rectangle when i would try to connect two such rounded rectangle figures. So, for that purpose i want to know some algo or method that wld get the points on the edge of the rounded rectangle.
