一种通用矢量图形闭合区域填充算法
首发时间:2009-02-27
摘要:本文给出了一种基于Mesh管理的通用矢量图形闭合区域填充的解决方案。该算法中,构成图形区域边界的线均为贝塞尔曲线,通过贝塞尔曲线的求交算法和自身锚点确定节点,边,路径,面等用于区域搜索的数据结构。在这些数据结构信息的关联下, 实现了用表达不同意义的颜色填充区域。由于该区域是一个由矢量化线段组成的区域, 从而可以实现不同比例、不同方向的变换。为图形输出提供丰富的形式和图形文件保存节约了大量空间。该方法己在PC 机上实现。

A General Arithmetic To Fill Vector Graphics With Close Region
Abstract:This paper provides a general resolvent to fill vector graphics with close region based on Mesh’s administration. In this arithmetic, all graphics border of lines are Bezier curves, the region searching of data structure which contains node, margin, path and face is defined by the intersecting arithmetic of Bezier curve and the control points of it. On the association of this data structure, that using different colors to fill different regions can be implemented. Because these regions are composed of vector lines, they can be transformed by different scale and different orientation, further more, it can provide many abundant types for graphics of output and economize memory for saving files. This arithmetic has been implemented on PC machine.
Keywords: Bezier Curve Close Region Fill
