从svg转换为pdf

Question

我正在尝试用以下代码把一个svg文件转换成pdf，但遇到了错误。

源代码：

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

错误信息：

pydev debugger: starting

    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，我想避免使用硬盘文件，而是想用StringIO来创建一个临时的svg/pdf文件，但我想svg2rlg似乎只接受文件路径作为输入。

为了让它正常工作，我手动编辑了：

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

并且添加了这个缺失的部分：

import string
