矢量图的漫游显示

Display wandering of vectorized graphics

在分析矢量图形特点的基础上，提出了两种矢量图漫游显示的方法：一种是针对显存容量大、可分页的情况的漫游；另一种是针对显存容量只有一页的漫游．本文着重讨论了实现后一种情况的漫游所采用的各种技巧及一些具体问题的解决方法．

Based on the analysis of the characteristics of vectorized graphics,two methods are proposed for display wandering of vectorized graphics. One is wandering about the video buffer that has large volume and several pages,another is wandering about the video buffer that has only one page. Emphasis is put on the techniques which are used in the latter display wandering.
