Hello,
the PDF/A-3A standard defines, that the interpolation of images in a PDF/A document must be disabled.
After the conversion of our documents (from PDF to PDF/A) and a validation through an online validator, following error appeared:
<validationreport profilename="PDF/A-3B validation profile" statement="PDF file is not compliant with Validation Profile requirements." iscompliant="false">
<details passedrules="123" failedrules="1" passedchecks="2536" failedchecks="2">

</check>
</rule>
</details>
</validationreport>
From the error message I deducded that the interpolation for the images should be false, but is true.
Furthermore, I could see that the image is an inline image which doesn’t appear in the Documentpage.Resources.Images Collection
Is it possible to transform the original PDF file to a PDF/A file and to deactiviate the interpolation?
Thank you very much in advance,
Best regards
