Design of the Advanced GDI+ Extensions
|
To accommodate the new features, we extend the design by adding two new components: the rectangular frame and the ellipsoidal frame. In addition, we declare new member variables to hold additional information that is needed to draw the graphics primitives with the specified color and line width. Figure 7.2 shows the updated class diagram of the photo editor. |

Now that the design is specified, we have some project management issues to take care of before we start the implementation of the new features.
