Convert PowerPoint to PDF/A-2u format - text spacing messed up?

It seems that there’s some issue when the conversion of text in PowerPoint files into PDF/A-2u format?

Sample PowerPoint.pptx:
PowerPoint.zip (24.3 KB)

Original screenshot of how it looks like:

Converted to PDF/A-2u:
PowerPoint.pptx.pdf (16.9 KB)

How the converted PDF/A-2u looks like:

I’m testing the fix.

While it is confirmed that v24.5 has resolved the issue, I’m encountering a very odd situation whereby it takes very long for the first conversion to complete.
Subsequent conversions are fast.

The first conversion for the simple PowerPoint.pptx sample provided earlier above takes almost 3 minutes to convert to PDF/A-2u.

We couldn’t not reproduce this issue at our end using following Presentation file.

The conversion took almost 18 seconds image.png (141.8 KB). Could you please share the sample application and the problematic file using that issue could be reproduced?

I’m using the same sample file.
Perhaps it is just that my machine is slower?
I think 18 seconds is still too slow for such a simple sample.
Noted that simple MS Word documents convert much faster.

Also, I was testing the new PresentationLoadOptions - removing the below seems to speed things up even though the sample didn’t contain any embedded files.
Please try adding the below to confirm if it increases your conversion time.

    if (nativeFileType is GroupDocs.Conversion.FileTypes.PresentationFileType)
    {
        return new GroupDocs.Conversion.Options.Load.PresentationLoadOptions
        {
            ConvertOwned = true
        };
    }

Hi, any updates on this issue?

Noted in GroupDocs.Conversion for .NET 24.7 Release Notes

That there’s a similar bug fix for Word to PDF:

CONVERSIONNET-6900 Bug Particular Word to PDF conversion taking a lot of time

@jarrodwee

Please note that the issue CONVERSIONNET-7005 is still under investigation.

Could you please share this particular Word file and the conversion code as well.

Apologies for the confusion, not reporting any issue with Word to PDF conversion - just noting that it has been resolved in the latest Conversion.NET - was hoping that it might have also been resolved for PPT to PDF.

@jarrodwee

Yes, we are already working on this issue. You’ll be notified in case of any update.
