Convert EMF/WMF files to PNG/JPG

Question

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.

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).

The code is somewhat simple:

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))

The error i get is:

IOError: cannot find loader for this WMF file

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

Is there a solution for me on a linux system?

Thanks.

EDIT:

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?

Answer 1

pip install Pillow

from PIL import Image

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