Python实现PDF与SVG的相互转换

简介：本文将介绍如何使用Python实现PDF与SVG之间的相互转换。我们将使用PyPDF2和svgwrite这两个库来完成这个任务。

在Python中，我们可以使用PyPDF2和svgwrite这两个库来实现PDF与SVG之间的相互转换。下面是一个简单的示例代码，演示了如何将PDF文件转换为SVG文件，以及如何将SVG文件转换为PDF文件。

首先，我们需要安装PyPDF2和svgwrite库。在终端中运行以下命令来安装它们：

pip install PyPDF2 svgwrite

接下来，我们来实现PDF到SVG的转换。

将PDF转换为SVG：

import PyPDF2
import svgwrite
def pdf_to_svg(pdf_path, svg_path):
    # 打开PDF文件
    with open(pdf_path, 'rb') as file:
        reader = PyPDF2.PdfFileReader(file)
        # 获取PDF页数
        num_pages = reader.numPages
        # 循环遍历每一页并将其转换为SVG
        for page_num in range(num_pages):
            page = reader.getPage(page_num)
            # 将页面内容转换为SVG字符串
            svg_str = page.extractText()
            # 将SVG字符串写入文件
            with open(svg_path, 'w') as svg_file:
                svg_file.write(svg_str)

将SVG转换为PDF：

```python
