编辑:添加了用于生成rst的makefile
最佳答案
我想我知道为什么会这样:问题出在 sphinx.ext.imgmath 扩展名+ hf-tikz无法与DVI文件一起正常工作。
在转换数学方程式时，sphinx将创建一个非常基本的 latex 文档，并使用latexpdf将其编译为DVI文件。之后，将文件转换为SVG，然后将生成的svg文件复制到sphinx的_build目录。问题是dvisvgm(由imgmath使用)无法转换tikz内容。另一种选择是使用扩展的DVI，但效果也不佳。
解决方案是将所有内容都编译为PDF，然后将该PDF转换为SVG。这有点问题，我发现的唯一方法是使用pdf2svg + pdfcrop。我最终将imgmath.py修改为自定义扩展名。以下是我在imgmath.py中所做的更改。所做的更改需要使用外部应用程序，因此，我认为创建拉取请求没有任何好处(至少不是使用可扩展性更高的解决方案)。imgmath.py中的更改:
def convert_pdf_to_svg(pdfpath, builder):
# type: (str, Builder) -> Tuple[str, int]
"""Convert DVI file to SVG image."""
tempdir = ensure_tempdir(builder)
filename = path.join(tempdir, 'math.svg')
name = 'pdfcrop'
command = [name, pdfpath, pdfpath]
run_external_command(command, name)
name = 'pdf2svg'
command = [name, pdfpath, filename]
run_external_command(command, name)
return filename, None
compile_math函数的try块中，将return语句替换为以下if builder.config.imgmath_pdf2svg:
return path.join(tempdir, 'math.pdf')
else:
return path.join(tempdir, 'math.dvi')
render_math方法内部，在块标题# .dvi -> .png/svg中，将try块替换为以下try:
if image_format == 'png':
imgpath, depth = convert_dvi_to_png(dvipath, self.builder)
elif image_format == 'svg':
if self.builder.config.imgmath_pdf2svg:
imgpath, depth = convert_pdf_to_svg(dvipath, self.builder)
else:
imgpath, depth = convert_dvi_to_svg(dvipath, self.builder)
except InvokeError:
self.builder._imgmath_warned_image_translator = True # type: ignore
return None, None
imgmath.py的最后添加一个新的配置条目: app.add_config_value('imgmath_pdf2svg', False, 'html')
之后，您可以写入 conf.py 以启用tikz图像。
imgmath_image_format = 'svg'
imgmath_latex = 'latexmk'
imgmath_latex_args = ['-pdf']
imgmath_pdf2svg = True # Available only in the custom `imgmath.py`
imgmath扩展名的补丁。 包括其他一些东西:)
