Compute the dimensions of the new Picture object

The code in Listing 5

• calls the getTransformEnclosingRect method
• on the previously scaled Picture object
• passing a reference to the rotation transform object
• to get the required dimensions for a Picture object
• that will contain the rotated image.

Listing 5. Compute the dimensions of the new Picture object.

    Rectangle2D rectangle2D = 
           pic.getTransformEnclosingRect(rotateTransform); 
 
    int resultWidth = (int)(rectangle2D.getWidth()); 
    int resultHeight = (int)(rectangle2D.getHeight());
