We use Aspose.PDF Java library to convert files from PDF to PDF/A format in order to remove transparent objects from a document. Recently, we’ve bumped into issue for one PDF file which contains many images.
The PDF/A standard compliance checks shows the following error: Transparency used (soft mask in image)

The library version is aspose-pdf-17.7.0
Could you help us to fix that?
Thanks in advance,
