Hi,

I'm trying to resize rotated node, not via resize handles but just changing the node Size (DiagramAdapterNode.Resize(w,h)

the problem is that when node is rotated the locations is changing not in proper way - i.e when node is rotated 45deg, and when resizing via right bottom handle - the left top position is kept, but when I resize the node via Resize method the location is moved. How to achieve the same behavior when resizing node the same as when resizing via resize handles ?

Regards,

Hi,

Try this method -
[code]
void Resize(DiagramNode node, double width, double height)
{
     var topLeft = new Point(0, 0);
     topLeft = node.TransformItemToDiagram(topLeft);

     double rad = node.RotationAngle * Math.PI / 180;
     var rightVector = new Vector(
           width * Math.Cos(rad), width * Math.Sin(rad));
     rad += Math.PI / 2;
     var downVector = new Vector(
           height * Math.Cos(rad), height * Math.Sin(rad));

     var bottomRight = topLeft + rightVector + downVector;
     var center = topLeft + rightVector / 2 + downVector / 2;
     var rotate = new RotateTransform(
           -node.RotationAngle, center.X, center.Y);
     topLeft = rotate.Transform(topLeft);
     bottomRight = rotate.Transform(bottomRight);
     node.Bounds = new Rect(topLeft, bottomRight);
}[/code]

Thanks,

adapted it to work in all expand/shrink directions.
Don't you thought about putting it to the API or if already is hidden make it public ?

I guess we could add a pivot-point argument to usual Resize method, we'll have it in mind for next releases.
