产生

使用 Xelatex 进行编译---我已经能够勾勒出单词的轮廓（\contour似乎不起作用），但我还没能弄清楚如何将类似的轮廓技术应用到图像psvectorian（在本例中是羽毛）上。

有人知道在使用编译代码时执行此操作的方法吗xelatex？

Answer 1

只是一份草稿。

我必须提供一个新的 PostScript 标头 ( mypst.pro)，它分叉羽毛的定义（编号 94）并fill用（先描边然后填充）替换原始路径操作gsave <setting color> stroke grestore fill以产生轮廓效果。

我不知道为什么设置\psset{linecolor=...,fillcolor=...,...}不起作用\mypsvectorian。因此，到目前为止，它是用in<setting color>硬编码的。0 setgraymypst.pro

% !TeX TS-program = xelatex
