将 EMF/WMF 文件转换为 PNG/JPG [英] Convert EMF/WMF files to PNG/JPG

问题描述

我收到一个带有 Word docx 文档的表单上传.我成功完成了所有解析.然后我必须在网络上显示该 Word 文档.

I am receiving an form upload with a Word docx document. I got all the parsing done successfully. I have to then display that Word document on the web.

我此时遇到的问题是我嵌入了 EMF 文件(PIL 库将其识别为 WMF 格式)，我无法弄清楚如何将它们转换为可以在网络上显示的内容(任意选择)PNG).

The problem I am running into at this moment is that I have embedded EMF files (that the PIL library recognizes as WMF format), and I cannot figure how to convert them to something that can be displayed on the web (arbitrarily chosen PNG).

代码有点简单:

im = PIL.Image.open(StringIO.StringIO(data))
fmt = im.format
if (fmt == 'WMF'):
  fmt = 'PNG'
  output = StringIO.StringIO()
  im.save(output, format=fmt)
  data = output.getvalue()
  output.close()
return '''<img src="data:image/{0};base64,{1}" />'''.format(fmt, base64.encodestring(data))

我得到的错误是:

IOError: cannot find loader for this WMF file

这些 Word 文档来自普通用户，他们可能只是从网络上剪切和粘贴图像或从文件中插入.

These Word documents come from average user that may just have cut-and-paste images from the web or insert from file.

在 linux 系统上有没有适合我的解决方案?

Is there a solution for me on a linux system?

谢谢.

为了我的辩护，我尝试将该文档上传到谷歌驱动器，但图像也未显示.也许没有简单的解决方案?

To my defense, I tried to upload that document to google drive and the image is not displayed either. Maybe there are no simple solutions?

推荐答案

pip install Pillow

pip install Pillow

从 PIL 导入图像

Image.open("xxx.wmf").save("xxx.png")

Image.open("xxx.wmf").save("xxx.png")
