ShockwaveNN commented 2 years ago

Hi, could you clarify parameters you've used?

I've converted your file via:

curl --location --request POST 'http://localhost/ConvertService.ashx' \
--header 'Content-Type: text/plain' \
--data-raw '{
    "async": false,
    "filetype": "pptx",
    "key": "50ae2df7-f06d-4205-9a68-ea695cfbae1d",
    "outputtype": "pdf",
    "title": "PB.Preview.OO_INSAL_GoFAST_Tuto_Actions_enmasse.pptx",
    "url": "https://github.com/ONLYOFFICE/DocumentServer/files/7959685/PB.Preview.OO_INSAL_GoFAST_Tuto_Actions_enmasse.pptx"
}'

And everything seems fine (I've opened PDF in it Google Chrome and ONLYOFFICE DocumentServer): image

@ShockwaveNN we are checking and give you update next week. It is possible that it is that Onlyoffice PDF export in this case is incompatbile with PDF.js (LO and MS-Office working)

ShockwaveNN commented 2 years ago

incompatbile with PDF.js (LO and MS-Office working)

It may be, I think we got reports of problems with pdf.js earlier, but if file is renders fine in Google Chrome, LibreOffice and Word - this should be reported as bug in pdf.js library

cpot commented 2 years ago

Not exactly, PDF exported from LibreOffice or MS-Powerpoint is correctly displayed by PDF.js, not PDF export from Onlyoffice

ShockwaveNN commented 2 years ago

@cpot Sorry, correct me if I got you wrong, but I've meant another thing

  1. Export pdf from ONLYOFFICE DocumentServer
  2. Open in in GoogleChrome or for example Adobe Acrobat or Okular (my default viewer on KDE) and pdf.js

And if this pdf is OK in Google Chrome, and Okular and not OK in pdf.js - I think it's the problem in pdf.js

I've rechecked resulting pdf in Mozilla firefox (as I understand it uses pdf.js by default) and I confirm that it renders incorrectly, but google chrome and Okular render ok

avanhovedev commented 2 years ago

Hi ! This is the render with firefox :

I confirm, so i think it's a pdf.js problem we will see and come back after we fix this bug.

Thanks,

cpot commented 2 years ago

But still, LO and Powerpoint export a correct PDF of this file in PDF.js ....

ShockwaveNN commented 2 years ago

Maybe because they use completely another engine or some specific operations

I thin the best way right now to handle this situation - file an issue to pdf.js and wait for their analyze of this problem

ShockwaveNN commented 2 years ago

I'll close this issue, seems pdf.js team accepted this problem (judging by their tags)

nicozhang commented 1 year ago

The same problem. The pdf.js team seems not accepted this problem.
