When creating custom properties in my presentation and saving as a PPTX file, I can see the properties in the PowerPoint inspector just fine. But when I save as PDF, they don’t appear in the Acrobat Reader properties inspector. I suspect this is a bug, or possibly a feature omission.
I noticed that other libraries, like Aspose.Words, have save options that must be explicitly set, e.g.
PdfSaveOptions options = new PdfSaveOptions();
options.ExportCustomPropertiesAsMetadata = true;
But this option does not exist in Slide’s PdfOptions class.
Thanks for your assistance. And, congrats on the tremendous improvements in the online documentation.
