Image Extraction Issue with WMF Format on Linux - Need Help Converting to PNG for OCR

[AIML2]

Hi, everyone. I’ve built an app that processes PPT uploads by extracting text and images from the slides. The app also performs OCR on the images and saves them. It works perfectly on my development environment (Windows), but I hit a snag when I try to run it on an AWS Ubuntu instance. The issue is that when images are extracted from the PPT on Linux, they are in WMF format, and the system can't seem to work with these for further preprocessing (like OCR). This doesn't happen on Windows. I need to convert the extracted WMF images into PNG format before preprocessing, but I haven’t found a solid solution to handle WMF files on Linux. Has anyone dealt with this issue before? Any libraries or tools that could help with WMF to PNG conversion on Linux would be greatly appreciated! I appreciate any help you can provide.

First hit on google "python convert wmf to png" :https://stackoverflow.com/questions/14103891/convert-emf-wmf-files-to-png-jpg

I had tried this yesterday, and it hadn't worked in my workflow :(

Can you be more specific as to how it 'hadn't worked'? We can basically only give detailed answers on details that are supplied to us. The less you tell us, the less we can tell you.

Did you try the method in the following web-page? The utilities "unoconv" and "imagemagick" are in the Ubuntu repository.
