1. Please don't ask to "fix it now!", this is quite rude and many people work on a volunteer basis for this project.
2. You talk about converting from PDF to PNG but your command converts to PDF. Please clarify.
3. Please test with the latest release

Thank you

Correct command line arguments:--headless --convert-to png inoutFile --outdir outputFolder
Comment 4 siyi 2023-10-13 06:16:32 UTC 
This problem still occurs in the latest version
Comment 5 Stéphane Guillou (stragu) 2023-10-13 13:12:43 UTC 
I tested with:

libreoffice7.6 --headless --convert-to png renamed.pdf

Indeed, the process hangs. I stopped it after three minutes.
But I was able to use the same command on other sample PDFs (single-page and multi-page).

This kind of conversion should work, at least for the first page: https://ask.libreoffice.org/t/convert-total-pdf-pages-into-images-command-line/5377
https://stackoverflow.com/questions/41802507/how-to-convert-pdf-files-to-jpg-with-soffice-command
For converting all pages, see this Ask.LO question, which suggests an imageMagick option: https://ask.libreoffice.org/t/use-soffice-to-convert-from-doc-to-png-images/41621

So the issue lies in this particular sample file.
LO also hangs on importing the PDF into Draw.

Version: 7.6.2.1 (X86_64) / LibreOffice Community
Build ID: 56f7684011345957bbf33a7ee678afaf4d2ba333
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

Same in OOo 3.3, so inherited.
Comment 6 Stéphane Guillou (stragu) 2023-10-13 13:15:09 UTC 
With a recent trunk build, I get in the terminal many repeated:

warn:sdext.pdfimport:548997:548997:sdext/source/pdfimport/tree/pdfiprocessor.cxx:121: PDFIProcessor::setMiterLimit(): not supported by ODF

Then it gets stuck after one:

warn:xmloff:548997:548997:xmloff/source/draw/ximpstyl.cxx:365: unknown attribute urn:oasis:names:tc:opendocument:xmlns:style:1.0 style:writing-mode value=lr-tb
Comment 7 Dave Gilbert 2024-02-29 13:55:54 UTC 
Seems to work with my fix of tdf#113050 and I see that the file does use that type of fill; all the slides have this pretty stippled background.
