when you click on Insert Text it will draw only rectangle on image the text will not get displayed in that rectangle so please tell me what changes I will do in this so that text in rectangle will be visible and how i will get the location and height and weidth of that rectangle.
Also please tell me how should I provide rotate points to rotate that rectangle.Please replay soon.


Thanks

Hi,

please find the demo project attached, please tell me how to make text visible and how I will get the final location,height and width of text rectangle because i have checked it with bounding rectangle property of edit object but by that I got changed Height and width but the location remains same and how to provide rotate control points to text rectangle so that to move the text .Please reply soon.

Thanks
Manju
