How to get length and width of a bounding box?

edit

Basically a bounding box is stored as a rectangle. This means that you have the following parameters stored

EITHER

• Left top corner point
• Right bottom corner point

OR

• Left top corner point
• Width and height

In both cases you can use the properties of a rectangle to access it dimensions. A small code snippet

Rectangle retrieved_rectangle;
int width = retrieved_rectangle.width;
int heigth = retrieved_rectangle.heigth;
