How can i transform a shape ?

Posted by Francisco Ca�ete on June 07, 2000 at 5:23 PM

Hello, i hope u can help me.
I rotate rectangle by executing these sentences:
...
r2 = new Rectangle2D.Float(50,50,50,100);
AffineTransform rot45 = AffineTransform.getRotateInstance(90,0.0,0.0);
g2d.setTransform(rot45);
g2d.draw(r2);

But what i really want is to get the new coordinates of the rotated
rectangle, because if i ask for X,Y points the response will be
(50,50), although the rectangle has been rotated 90 degrees.
If I try to create a new rectangle by calling createTransformedShape, i
get an executing error?!! This is the code:

Rectangle b = new
Rectangle((Rectangle)rot45.createTransformedShape(r2));

I 've tried the same with line2d and the same has happened. Can tell me
how can i get the new coordinates of a shape after rotating it ?


Thanks for all
