Text background in docx is saved as image after PDF conversion

Document Server version: 7.1.1 docker

Hi,
I’m facing an issue when converting a docx file to pdf - the docx file has a background pasted in the head of the page (the letter form with address etc. in this case). This background contains mainly text and vector-based logos.
After conversion to pdf (download as pdf in ONLYOFFICE or convert via API call), all that background gets converted to an image apparently, which causes artefacts when zooming in or printing. Zooming into the docx is fine though.

Example on heavy zoom:

pdf from ONLYOFFICE:
pdf_OO

When I do the same with Word (open docx and export as pdf), the pdf looks sharp.

Also, the pdf created by Word is way smaller than the one created by ONLYOFFICE (167 kB vs. 415 kB).

Are there any settings to optimize the pdf export in document server?
I can provide the full example files if useful, I just can’t paste them here in public (but e. g. send via mail).

Thanks in advance!

Hello @ips-ad
Recently we released Document server v.7.2. Could you please update your installation and re-check the situation? If issue still persists, you can contact me via PM and provide an example of file where the issue reproduces and compare screenshots (MS Word\ONLYOFFICE results).

Thank you for the fast response, and sorry I missed v.7.2! I updated this morning and checked again, but the behavior is still the same. I’ll send you a link to the examples via PM :slight_smile:

Hello @Alexandre, I saw in the release notes that svg support has been added for all editors, this is great.
However I’m still wondering when it’ll be possible to have the pdf exports of e.g. a docx document (containing an svg) generated with true vector-based elements, too? It’s still not possible to work with svg-based letterheads, as the result isn’t sharp enough for good printing anymore.

I just tested with Document Editor 7.5.1.23: Created new docx, added an svg image and exported all to pdf.

Result:

Expected:

By the way, this is a test svg file from Wikipedia (https://upload.wikimedia.org/wikipedia/commons/b/bd/Test.svg). It also loses it’s text elements in pdf:

Thanks for any updates on this topic :slight_smile:

Hello @ips-ad
Sorry for the late reply.

I just tested with Document Editor 7.5.1.23: Created new docx, added an svg image and exported all to pdf.

Please provide us with a test file (original docx file, before exporting to pdf).

By the way, this is a test svg file from Wikipedia (https://upload.wikimedia.org/wikipedia/commons/b/bd/Test.svg). It also loses it’s text elements in pdf:

This one as well. The mentioned link doesn’t contain any data that is related to your screenshots. I see only a medical picture with a human digestive system, but not the colored table with TEST text.

However, I’ve checked scenario with new docx file > paste this svg picture > save as pdf. The final result looks OK. But I would like to check the situation with ‘loses it’s text elements in pdf’ as you mentioned
