I really need some advice on how to implement features below:
A user clicks an icon (I will provide it), then clicks again in a drawing area, a shape represented by the icon will be there. If a user (right) clicks on the shape, a popup menu will come out with several options, like Add a solid line, convert it, etc. If a user selects "add a solid line", a solid line will be extened from the shape, with an active hot spot at the end. If clicking the hot spot, a user will get the same popup menu again. Users can drag the line to scale it.
If the user selects "convert it", the shape will become another equivalent shape.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
