PDF-export does not succeed

Describe your problem or propose a new feature in the following sections. Keep the headings and replace the paragraphs with your own text.

Summary of your problem or feature request

Trying to export result into PDF. Separate pop-up window opens, shows first slide and then stops. No PDF-file is produced. Then I just close Sozi. I used earlier SVG-file and Sozi files, just edited a bit and wanted to export into PDF again.

Version of Sozi and other relevant software

• Which version of Sozi are you using? v22.03.25
• Which drawing software did you use? Inkscape 1.2.1 (9c6d41e410, 2022-07-14)
• On which platform? EndeavourOS with KDE, all updates done + rebooted, still not exporting PDF
• If your problem happens when playing a presentation, which browsers have you tried? No issues here.

Steps to reproduce the problem

• open *.svg file
• make some slides in Sozi
• try to export PDF
• additional window opens but nothing more and no PDF created

Expected behavior

PDF-file is produced

Observed behavior

No PDF-file.

Hints and solutions (optional)

Tried also *.AppImage - still same issue. Haven't exported since this version came out, so did not discover, that PDF-exporting is not working. I guess that separate pop-up window would not be needed. I remember from earlier times, that each slide will be showed in that pop-up window during export. I guess we have seen our document already in Inkscape, Sozi. I propose to allow to configure in Sozi, whether such pop-up will be opened during export or not.

It would help if you could check the JavaScript error console while running the PDF export and tell me whether you get error messages. See Helping debug Sozi for details.

I will try to reproduce the problem in your specific OS, but PDF export should be platform-independent.

I propose to allow to configure in Sozi, whether such pop-up will be opened during export or not.

To save each page of the PDF, Sozi needs to display it in a window. It would be great if we could hide this window but last time I checked it did not work.

I guess I don't need to include those referred files as you presumably already have them. EndeavourOS can be downloaded here. You can easily test as live session either in virtual machine or Live USB. For Live USB stick/disk is easy way to use Ventoy.

Pop-up window can be if needed. Just guessed, that perhaps it is not necessary to show it and if not shown, perhaps the load for computer is smaller. Just could not find practical value for pop-up window. But most critical, that PDF-export works.

When you wrote:

I remember from earlier times, that each slide will be showed in that pop-up window during export.

Did you mean that in the current version you didn't see each slide in the pop-up window?

That's true...

OK. So it means that rendering your presentation fails even before attempting to save it to PDF.

I understand that you do not use this feature often. Have you tried to export several presentations and got the same error, or dit it work in some cases ?

[edmundlaugasson]

Actually HTML-version of presentation is rendered fine. Only PDF-exporting fails.

I understand that you do not use this feature often.

Actually I need to export near every presentation into PDF also. People would like to print them also out. Certainly I can send also *.html file but somehow PDF is quite often preferred by people, I guess due to printing need mainly. Actually also people cannot select+copy text from HTML but from PDF there is possible to select and copy text. E.g. hold certain key to pause animation and just allow to select+copy text would be appreciated. Currently I solve it so, that I make also *.svg available - then people can select and copy text from there.

Does not matter, which presentation I try to export - none works. I tried to create brand new slides in Inkscape and then export via Sozi into PDF - did not work either. In same computer and OS with earlier version of Sozi I've exported PDFs.

[aumouvantsillage]

I have just published a Beta release that addresses this issue. I had to upgrade several pieces of software that Sozi uses internally, so I think it still deserves a testing period before being officially considered as the new stable release.

[edmundlaugasson]

Thank you! Now I could export to PDF and that PDF opened fine and was readable. I used AppImage version. Here is the output from command line:

Thanks for your feedback. The error messages that you see can be safely ignored.

I can confirm that the export to pdf works now.

[RichardScharf]

I encountered the same problem. Slides do not progress on .pdf export (only pptx works) OS: Linux Mint 21.1 x86_64 Sozi Version: 22.03 (.AppImage)

Running .pptx export from terminal yields the following warning message: (node:40464) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

[aumouvantsillage]

@RichardScharf This issue is supposed to be solved by version 22.09 Beta. Have you tried it.

[kingofbroccoli]

I used to have the same issue with the official v22.03.25. I've updated to the Beta v22.09.23 and I can as well confirm that the integrated pdf-conversion tool is now properly working. Thank you very much!
