Document.Optimize corrupts pdf document

Aspose.PDF Product Family
1

Hello,


We’re using the Aspose.Pdf package v17.4.0 for .Net.
We’ve noticed that calling Optimize() on a specific pdf document causes it to become corrupted when saved to an output file (all the pages are blank when opened in Adobe Acrobat).
Currently, we’ve only seen it happen with this one document, so not sure what is going wrong.

Here’s some simple sample code:
Document doc = new Document(inputFile);
doc.Optimize();
doc.Save(outputFile);

If we remove the Optimize call, then the output is fine.
I’ve attached the document we’re seeing this with (InputDoc.pdf), and the corrupted output (OutputDoc.pdf).
Any help would be appreciated.

Thanks,
Luke

Hello, I seem to be experiencing this issue also with Aspose.pdf for Java (19.3). I know you have been working for a solution for .net since(or you have an open ticket to work on a solution), can we expect also a solution for java, and if yes is it likely to be soon ?

Thanks

We apologize for the inconvenience.

The issue has already been logged for .NET API and is pending for resolution due to other high priority implementations and enhancements. Furthermore, once the issue is resolved in Aspose.PDF for .NET, its fix will also be ported in equivalent version of Java API. As soon as the issue is resolved or we have any update in this regard, we will share with you.

Is this still an issue in .NET API version 24.4?
I’m seeing “Serialization error” when calling pdfDocument.Optimize();

It may be related to the specific document. Can you please share the sample PDF for our reference so that we can test the scenario in our environment and address it accordingly?
