--- Comment #5 from ricky.t...@gmail.com --- Correction; "From what I know so far ..." not "From what we know so far ..." as you wrote; you, alone. Talking about yourself in the first person plural is likely to sow confusion. Now, back to the subject. Transparent objects and layers (Optional Content Groups) are forbidden in PDF/A-1 (all variants) –allowed in PDF/A-2. Your sending request is beyond reasonnable. You cannot expect to receive confidential material that is not meant to be shared with Canonical. In this context, creating the condition to have such object inserted in an ODT document, must be left to your complete discretion, More importantly this is even a knowledge that a developer is expected to have for operating fluently. Though that's now for your convenience that i provide guidance; a snapshot taken in Linux might bring the desired transparency property. Otherwise as far as I managed to interpret you, you have ended up with an erroneous conclusion by stating that there would be no issue if a document (here mine) contains (with proof of it) a transparent object. That rather demonstrates something else though as what you say; your lack of ability to consider the whole report. Indeed, as you are taking account of PDF/A-1b separately, you are then missing to evaluate what causes this message to not be displayed when operating PDF/A-2b/3b exports. You are the developer here! -- You are receiving this mail because: You are the assignee for the bug.
