python - 从 svg 转换为 pdf

Question

我正在尝试使用以下代码将 svg 文件转换为 pdf，但出现错误

来源:

from svglib.svglib import svg2rlg
from reportlab.graphics import renderPDF
drawing = svg2rlg("test.svg")
renderPDF.drawToFile(drawing, "test.pdf")

错误:

    normPath = normaliseSvgPath(d)
  File "C:\Python27\lib\site-packages\svglib\svglib.py", line 146, in normaliseSvgPath
    a = string.replace(a, 'e-', 'ee')
NameError: global name 'string' is not defined

此外，我想避免硬文件并使用 StringIO 创建临时 svg/pdf 文件，但我猜 svg2rlg 只接受路径作为输入。

为了让它工作，我手动编辑了:

/Users/<MY_USER>/.virtualenvs/<MY_VENV>/lib/python2.7/site-packages/svglib/svglib.py

并添加这个缺失

导入字符串
