Hi during testing of aspose.pdf 18.8 we can see that compression does not work for some scanned document (when we do conversion from PDF to PDFA). I have added the testcode and the reuslt in an public google drive folder. https://drive.google.com/open?id=0BxDl-cavcm4ONXUzeVVybkQ0N3M
This folder is used for 2 different cases that we have here at aspose free support.
You can recreate the error with the consoleApp that we have provided.
You can see the error by setting CompressImages to true in
private void ValidateAndConvertToPDFA(Document doc, bool compress);
The test result is generated in bin\debug\Testresources folder.
Best Regards
Per Rodstrom
