真实世界实现中路径笔画变化的轶事调查
Anecdotal Survey of Variations in Path Stroking among Real-world Implementations
摘要:
勾画路径是矢量图形标准中的两个基本渲染操作之一(例如,PDF,SVG)。我们调查路径笔画渲染结果从现实世界中的软件实现路径笔画的轶事证据表明,这种实现容易渲染的差异。虽然我们的调查是有限的和非正式的,我们收集的渲染结果表明,广泛的渲染变化简单,但有问题的笔画路径几十年前首次确定。我们的结论是矢量图形内容的创建者将受益于一个数学接地标准化的描边路径应如何光栅化。
英文摘要:
Stroking a path is one of the two basic rendering operations in vector graphics standards (e.g., PostScript, PDF, SVG). We survey path stroking rendering results from real-world software implementations of path stroking for anecdotal evidence that such implementations are prone to rendering variances. While our survey is limited and informal, the rendering results we gathered indicate widespread rendering variations for simple-but-problematic stroked paths first identified decades ago. We conclude that creators of vector graphics content would benefit from a mathematically grounded standardization for how a stroked path should be rasterized.
