PPT to PDF: Textboxes underneath images appearing on top of image

[datermine]

I have a process that uses unoconv to convert PowerPoint presentations to PDFs (and then eventually PDFs to images), but quite often I have these sorts of artifacts where slide template textboxes are appearing on top of images that would normally occlude them.

For example:

Is this a known issue? Is there a way to fix this?

@datermine did you get any solution or any alternate way to do this. I also stuck in similar problem.

@Aabir1 -- Yup. I switched to using headless LibreOffice.

/usr/bin/soffice --headless --convert-to pdf test.key --outdir .

FYI - It's been giving me trouble with Keynote files though:

@datermine It seems strange that a direct conversion using soffice --headless would work correctly in this case. Could you by any chance have upgraded LibreOffice in the process ? Because this seems like a bugfix in LibreOffice, unoconv really doesn't do anything but call LibreOffice. (This is explained in the documentation)

If that's the case, then I have no idea how this got solved for me. I made the switch to calling soffice directly a little while ago and don't recall everything I did in the process.

@Aabir1 - perhaps you could let us know if soffice fixed your issue?
