我有一个 SVG 形状，我想将其用作 TikZ 节点边框。该形状基本上是带有描边效果的路径 - 但效果已被“嵌入”，因此现在我只有一个非描边路径作为最终输出；因此它看起来inkscape像这样：
因此，将其用作“适当的”边框将会很困难 - 所以我想要下一个最好的东西：也就是说，将“边框图像”缩放到矩形节点的大小。
源 SVG 在这里：自定义边框形状.svg。使用 中的 Tikz 导出器inkscape，我可以将相同的文件导出到tikz，该文件已粘贴为下面custombordershape_tikz.tex。（编译它，我获得custombordershape_tikz.pdf，它用于下面的测试代码）。
这时我发现了两个相关的问题：
第一种方法要好得多 - 但我没有足够的时间将图像中的路径转换为低级 pgf 命令，因此我只能使用缩放后的图像。这让我只能使用第二个链接中的方法，该方法除其他外还推荐\includegraphics。因此，这里有一个小型 MWE，test.tex，我用它来尝试一下：
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning}
\usepackage{lipsum}
\begin{document}
\begin{tikzpicture}
\node[draw=red] (n1) at (1,0) {\pgftext{\includegraphics[width=\linewidth]{custombordershape_tikz.pdf}}Testing};
\node[draw=red,align=left,text width=250pt,minimum width=250pt] (n2) [right=5pt of n1] {\pgftext{\includegraphics[width=\linewidth]{custombordershape_tikz.pdf}}\lipsum[4]};
\end{tikzpicture}
\end{document}
输出如下：
我希望 custombordershape 能够适合相应节点的红色边界框（最好是在文本后面；应该将颜色设为灰色来检查）；然而，显然结果并非如此。
那么，推荐使用什么方法来实现“自定义节点”（希望最终只能通过 tikz 样式调用）并使用可缩放至节点大小的外部背景图形？
鉴于我也有tikz路径格式的背景形状，是否有更简单的方法可以将其重新用于“自定义”节点定义，而不是\includegraphics在生成的 pdf 上使用？

答案1
嗯，这里有一种方法，path picture使用具有多种形状的 TikZ 节点并按照\includegraphics手册第 165 页“15.5 广义填充：使用任意图片填充路径”中的示例进行操作。诀窍基本上就是计算节点的大小，并将其应用于所包含图形的大小。这是输出：
请注意，较大的形状在右边缘有些错误地被剪裁；可以通过取消注释\p3代码中使用的手动位移来修复，但这有点蛮力的方法。如果有人知道更合适的方法来实现这一点，请发布答案。
