1. inkscape=true

在 LaTeX 中使用 \includesvg[inkscapeLaTeX=true]{...} 时，Inkscape 会将 SVG 图中文字交给 LaTeX 排版，而不是直接转成图形，这样图中文字就能与正文统一，并且像 \cite{} 这样的命令也能被识别执行，因此可以在图里成功引用文献。

2. 替换 \cite 的引用

替换 draw.io 输出的 xml 中的引用。

import xml.etree.ElementTree as ET

    Args:
        xml_content: A string containing the XML content of the draw.io file.

    Returns:
        A string with the modified XML content including BibTeX citations.

3. 修改替换后的 SVG 的 width 与 textLength

因为替换后的引用占用了过宽的 width，首先需要在 draw.io 导入替换后的 xml，重新导出新的 SVG。修改新 SVG 中的 width 和 viewport 为老的 SVG 的数值。

import sys
import xml.etree.ElementTree as ET

def get_svg_width_and_viewbox(svg_path):
    tree = ET.parse(svg_path)
    root = tree.getroot()
    width = root.get("width")
    viewBox = root.get("viewBox")
    return width, viewBox

def set_svg_width_and_viewbox(svg_path, width, viewBox):
    tree = ET.parse(svg_path)
    root = tree.getroot()
    if width:
        root.set("width", width)
    if viewBox:
        root.set("viewBox", viewBox)
    tree.write(svg_path, encoding="UTF-8", xml_declaration=True)

if __name__ == "__main__":
    if len(sys.argv) != 3:
        print("用法: python replace_svg_width.py old.svg new.svg")
        sys.exit(1)
    old_svg, new_svg = sys.argv[1], sys.argv[2]
    width, viewBox = get_svg_width_and_viewbox(old_svg)
    set_svg_width_and_viewbox(new_svg, width, viewBox)

import xml.etree.ElementTree as ET
import os
import sys

def modify_svg_text_elements(svg_filepath):
    """

    and lengthAdjust="spacing" to control the reported width for layout.

    and original <text> content (e.g., with \cite{}) leads to an oversized
    bounding box calculation by Inkscape.

    Args:
        svg_filepath (str): The path to the SVG file.
    """
    if not os.path.exists(svg_filepath):
        print(f"错误: 文件未找到于 '{svg_filepath}'")
        return

    ET.register_namespace('', "http://www.w3.org/2000/svg")

    try:
        tree = ET.parse(svg_filepath)
        root = tree.getroot()
        svg_ns = "{http://www.w3.org/2000/svg}"

        modified_count = 0
        for text_element in root.iter(f"{svg_ns}text"):
            text_element.set('textLength', '0')
            text_element.set('lengthAdjust', 'spacing')
            modified_count += 1

        if modified_count == 0:
            print("SVG中未找到或未修改任何 <text> 元素。")
        else:
            print(f"成功修改了 {modified_count} 个 <text> 元素。")
        try:
            ET.indent(tree, space="  ", level=0)
        except AttributeError:
            print("警告: ET.indent 不可用 (需要 Python 3.9+)。输出可能未美化。")

        tree.write(svg_filepath, encoding='UTF-8', xml_declaration=True)
        print(f"SVG文件 '{svg_filepath}' 已成功更新。")

    except ET.ParseError as e:
        print(f"解析SVG文件时出错: {e}")
        print("请确保它是一个有效的XML/SVG文件。")
    except Exception as e:
        print(f"发生未知错误: {e}")

if __name__ == "__main__":
    if len(sys.argv) < 2:
        print("用法: python text.py <SVG文件路径>")
        sys.exit(1)
    input_filepath = sys.argv[1]
    modify_svg_text_elements(input_filepath)

4. 神奇的垂直居中

仔细看，会发现在 LaTeX 渲染后，有些文字没有垂直居中。而且还与 width=\textwidth 有关，拷打 AI 也没有什么结论。考虑到使用频率，可以使用 \raisebox{-.5\height}{Hello} 自行微调。
