Dear Aspose Team,
I have converted the attached simple PowerPoint file
(in test0036.zip) to the PDF file
using Aspose.Slides for Java and further to the PDF/A-2B file
Both results look good and Aspose.PDF is consistent with itself in the
sense that it validates the resulting PDF/A file. However, two
external tools, i.e. Adobe Acrobat Preflight and veraPDF, see the file
as invalid, both reporting a missing Resources dictionary.
The situation is easy to reproduce with other PowerPoint files. On the
other hand, Aspose.PDF is claimed to follow Adobe Preflight for
validating PDF/A conformance. I wonder whether the tools nevertheless
have different interpretations for some part of the standard.
