The Design and Implementation of 2D Vector Graphics Interactive Tools Based on “Smart Handle

摘要：

This article summarizes several kinds of interactive tasks and tools in 2D vector graphic system,analyses an ordinary design idea for interactive tool.We find that it is difficult to find a point of balance between user experience and codes maintainability and extensibility.So we present a design idea for smart handle-based interactive tool.Handles are usually expressed as rectangles or circles when graphic-cells are selected.Smart handle is a concept proposed in this paper.Compared with the handle,smart handle knows how to operate its own graphic-cell.So a complicated interactive task is assigned to every smart handle.It proves that this is a better solution to solve a contradiction between user experience and codes maintainability and extensibility.
