Hi.
I am converting different documents to pdf/a and usually I need to generate pdf/a-1a. Some times the documents grow a lot, and I am hoping you can help me understand what is happening and hopefully find a solution to this.
PowerPoint.zip (1.7 MB)
In the attached zip-file is an example document, PowerPoint.pptx which is a 49 kB file. When generating a pdf/a-1a or pdf/a-1b the output file grows almost 20 times to 831 kB. But when generating pdf/a-2a, pdf/a-2b, pdf/a-3a or pdf/a-3b the target file actually shrinks to 45 kB. And when looking at the result, the pdf/a 2 and 3 files are visually much better looking.
With this example document I use Aspose.Slides.Presentation to save the PowerPoint as pdf and I use Aspose.Pdf.Document to convert the pdf to pdf/a. I have validated all the pdf/a output files using Adobe Preflight.
The attached zip-file contains the example powerpoint document and the six different generated pdf/a versions of it.
Thank you for your help!
Best regards,
