JS CS3 Page Item Dimensions

Question

Hi there
I'd like to change the width & height of a rectangle by certain increment. This can be easily done by manipulating geometricBounds.
However when the rotationAngle is other than zero everything goes off the rails.
I tried experimenting with horizontal & verticalScale but these are only relative changes. They might be useful if I knew how to get the original H&W of the rotated object. Unfortunately none of the rectangle's properties seems to be of any use.
My other attempt was through the angle, bounding box and trigonometric hell. I was successful with flat lines. 2D rectangles proved to be too much of a challenge for me. And I still don't think this is the right approach anyway.
So the question is: Is there any way to get or change the values in H & W fields in InD's control panel via JavaScript?
Thanks for help

Answer 1

Following is my attempt at writing a function for width and height. It appears to work on rotated and sheared objects. Can anyone tell me if I'm on the right track?
>function WidthAndHeight(myRectangle) // Returns an array [width,height]
]] var myRectangleTopLeft = myRectangle.resolve(AnchorPoint.topLeftAnchor, CoordinateSpaces.pasteboardCoordinates, true);
var myRectangleTopRight = myRectangle.resolve(AnchorPoint.topRightAnchor, CoordinateSpaces.pasteboardCoordinates, true);
var myRectangleBottomLeft = myRectangle.resolve(AnchorPoint.bottomLeftAnchor, CoordinateSpaces.pasteboardCoordinates, true);
var d1x = (myRectangleTopRight[0][0] - myRectangleTopLeft[0][0]);
var d1y = (myRectangleTopRight[0][1] - myRectangleTopLeft[0][1]);
var myWidth = hypotenuse(d1x,d1y);
var d2x = (myRectangleTopLeft[0][0] - myRectangleBottomLeft[0][0]);
var d2y = (myRectangleTopLeft[0][1] - myRectangleBottomLeft[0][1]);
var myHeight = hypotenuse(d2x,d2y);
return [myWidth,myHeight];
function hypotenuse(d1,d2)
]]]] d1 = Math.abs(d1);
d2 = Math.abs(d2);
return Math.sqrt ( Math.pow(d1,2) + Math.pow(d2,2) );
