使用svglib包在python中进行SVG 2 PDF转换对我的svg文件不起作用 [英] SVG 2 PDF conversion in python using the svglib package does not work on my svg file

问题描述

您好，



我正在尝试使用svglib和reportlab python包将一堆svg文件转换为pdf。



我正在使用一个小程序，我在相邻的帖子中找到了这个程序（

在python中将SVG转换为PDF [ ^ ]）



因此，组装后的转换器如下所示：

Hi there,

I am trying to convert a bunch of svg files to pdf, using the svglib and reportlab python packages.

I am using a small program, that I found in a neighboring thread (
Convert SVG to PDF in python[^] )

So, after assembling the converter looks like this:

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

我使用以下svg文件测试它：

I tested it with the following svg file:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" 

"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
 
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" height="1000.0" width="1000.0">
  <circle cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="blue" />
</svg>

就像魅力一样。

我的真实文件就是这个：

Works like a charm.
My real file is this one:

<?xml version="1.0" encoding="utf-8" ?>
<svg baseProfile="full" height="210.0" version="1.1" viewBox="0,0,297.0,210.0" width="297.0" xmlns="http://www.w3.org/2000/svg" xmlns:ev="http://www.w3.org/2001/xml-events" xmlns:xlink="http://www.w3.org/1999/xlink"><defs><style type="text/css"><![CDATA[

这里没有运气，只是一个空白的pdf文件。

我哪里错了？

我很感激任何提示！如果您需要更多信息，请告诉我。



提前致谢！

No luck here, just a blank pdf file.
Where am I wrong?
I am thankful for any hint! Please tell me if you need more information.

Thanks in advance!

推荐答案

我不知道真的知道这是否有帮助，因为我不熟悉你正在使用的工具，但我尝试粘贴你的SVG下面我发现CodeProject的HTML东西在接受SVG时有点挑剔而且直到我才显示图像删除了CDATA部分中的空格和换行符（我实际上认为CDATA部分可能是真正的问题）。

再次，我不知道当你引入那些空格和换行符时将SVG元素粘贴到您的问题中，但我认为值得一试。

BTW，图像非常无聊:)。

I don't really know if this helps because I am not familiar with the tool you are using, but I tried pasting your SVG below and I found that CodeProject's HTML thingy is a bit picky when it comes to accepting SVG and it did not display the image until I removed the spaces and line breaks within the CDATA section (I am actually thinking the CDATA section could be the real problem).
Again, I don't know if those spaces and line breaks were introduced when you pasted the SVG element into your question, but I think it is worth a shot.

BTW, the image is pretty boring :).
