绘制柯尼斯堡风景，展示桥梁

只是为了好玩，我试着画了这幅画（我发现这里)：

但是，我不知道如何在中创建不规则形状tikz。有人可以帮忙吗？

答案1

这是您的身材的可能复制品。

我只是将图像放大，然后在 Gimp 中手动追踪轮廓的坐标（像素），然后填充必要的区域。代码很长，而且不太好。:)

如果您不介意没有精确的复制品，那么可以相当简单地获取所需图像的要点：

\documentclass[tikz,border=5]{standalone}
\usetikzlibrary{decorations.pathmorphing,topaths}

当然，可以优化跟踪...只是为了提高速度。

下一步：搜索 svg2tikz 转换器...

不使用Export to Clipboard会导致错误：

Traceback (most recent call last):

  File "tikz_export.py", line 1415, in <module>

    main_inkscape()

    file = __builtin__.open(filename, mode, buffering)

IOError: [Errno 13] Permission denied: 'Test'

我必须登录 Github 才能从https://github.com/kjellmf/svg2tikzextensions。然后我将和文件夹中的文件inkexlib直接放入C:\Program Files (x86)\Inkscape\share\extensions。其中一些文件已经在那里了。

最后的话：

这个答案被否决了。不知道为什么……以为这是一个“只是为了好玩”的问题。
