With the 3G development, more and more rich media applications appear on mobile devices. The efficiency of scalable vector graphics player is very crucial for constrained mobile devices. In this paper, we propose a partial rendering algorithm which dynamically traces the invalid areas of elements in the scene and rationally divides the scene into several partial rendering areas. Compared with the traditional algorithms, this algorithm can obviously improve performance on high resolution mobile devices. We also present a new contour algorithm for fitting circular arc, which uses midpoint rule to calculate the control points of cubic bezier curve. This algorithm has lower complexity than the traditional algorithms and is suitable for arc drawing on mobile devices. The test results show that above two algorithms have good effect on rendering optimization.
