如何将 tikzpictures 导出为 png 以在 PowerPoint 中使用？

我用 LaTeX 为我的论文制作了不少图表。现在我想将其中大约五个图表导出为具有清晰背景的 .png，以便在 PowerPoint 演示文稿中使用它们。我正在使用 TexStudio 和 MikTex。我找到了一些关于此内容的旧帖子（通过命令行将 TeX 转换为图像，如何在徽标中创建透明背景？，如何去除 png 图片的背景，制作具有透明背景的图像)，但似乎没有一个能回答我的问题。

例图：

\usepackage{pgfplots}
\pgfplotsset{

    % created a style for the common `ybar' options

        % state absolute positions for the `nodes near coords'
        scatter/position=absolute,
        node near coords style={
            % state where the nodes should appear
            at={(\pgfkeysvalueof{/data point/x},0.5*\pgfkeysvalueof{/data point/y})},
            anchor=center,rotate=90, %<-added

    },

是否有类似的命令 \savefig{'my_export_image.png', clear = True}？

如果只是 tikz 图片，你可以尝试使用 Troy Henderson 的 Latex Previewerhttp://www.tlhiv.org/ltxpreview/。只需在“包”下添加 tikz 包，然后您可以选择想要的输出类型 - 例如 png。

最近发现它并且运行得很好！
