如何在 Inkscape 中使用 LaTeX 将 SVG 图像转换为 PNG？

如何在 Inkscape 中使用 LaTeX 将 SVG 图像转换为 PNG？

我正在使用 Inkscape 绘制图像，同时能够生成包含所有文本的单独 LaTeX 文件，如所述这里。到目前为止，效果很好，但现在我只能使用.png、.jpeg或.bmp来处理我的数字。

有没有办法让我继续使用 Inkscape 和 SVG + LaTeX，然后从 SVG + LaTeX 图像转换为其他格式（例如.png），使得与文档中包含的 SVG 相比，LaTeX 字体及其缩放比例保持不变？

附加信息：

如果我只是在 Inkscape 中绘制 SVG，将 LaTex 内容添加到图片并将其导出为位图，那么 LaTex 文本当然不会被处理。

如果我使用 TexTex，字体的缩放将会丢失，这通常是包含在 SVG 中的。

安装inkscape2tikz。以下示例取自inkscape2tikz 主页。

在此处输入图片描述

使用 inkscape2tikz 我们将其导出到 tikz 代码：

\documentclass{article}

将此文件命名为image.tex（例如）。以下是您的main.tex文件。将image.tex和main.tex放在同一文件夹中。对于此示例，我已image.tex添加filecontents。

\documentclass{article}
\usepackage{graphicx}
\usepackage{charter}                  %%%% Added for demo of fonts Keep this in image.tex also to have same fonts
\usepackage{filecontents}
\begin{filecontents*}{image.tex}      
    \documentclass{article}            %%% tex file for image begins
    \usepackage{tikz}
    \usepackage{charter}               %%%% Added for demo of fonts

这假设您已经安装了 imagemagick。

答案2

要安装，svg2tikz您应该将tikz_extport.py文件和tikz_export_effect.inx文件复制tikz_export_output.inx到您的inkscape/share/extensions directory，如以下链接所述https://code.google.com/archive/p/inkscape2tikz/。但此链接提供了对文件的下载引用，，tikz_extport.py安装后无法使用。tikz_export_effect.inxtikz_export_output.inx

从此链接下载扩展文件（适用于 Inkscape v.0.91），然后按照上面的安装说明进行操作：

https://raw.githubusercontent.com/kjellmf/svg2tikz/master/svg2tikz/extensions/tikz_export.py

https://raw.githubusercontent.com/kjellmf/svg2tikz/master/svg2tikz/extensions/tikz_export_effect.inx

https://raw.githubusercontent.com/kjellmf/svg2tikz/master/svg2tikz/extensions/tikz_export_output.inx

如果扩展已正确安装，您将在“效果”->“导出”->“导出到 TikZ 路径...”菜单中找到导出器。您还可以选择“另存为”，并选择 TikZ 代码作为输出格式（适用于 Inkscape v.0.91，但据我所知，不支持 v.0.48.5）。
