Open marcosps opened 11 years ago

marcosps commented 11 years ago

Hi guys!

I never saw this warning before, so I'm opening this issue: [13:58:53.651] "Warning: TODO: Support knockout groups." [13:58:53.651] "Warning: TODO: Support non-isolated groups."

Here is a link to the pdf with the error: http://dc230.4shared.com/download/XnQb9rEQ/LM-ED04.pdf

Not sure if this is directly relevant, but the following document is giving me Warning: Knockout groups not supported.: https://pdf.yt/d/1XdBtONLh-nGcAyv

Adding a really good PDF-X4 support document to show in Adobe and PDF.JS (see Page 2 - #10 - for Knockout support). I'll open another issue for overprint support.

I've got another instance of this affecting rendering of a PDF that works in all other browsers and Acrobat Reader.

I get the same message "Warning: Knockout groups not supported.". Are there any internal changes lined up for the future that implements better support for knockout groups?

marcosps commented 5 years ago

Five years after opening the bug, I just found another example of the same warning:

Still reproducible with current Nightly flatpak.

SandMoshi commented 4 years ago

Can someone explain to me why the warning is there and what should be done about it?

lovewinders commented 3 years ago

I upgraded the pdfjs version to 2.5.207, the same problem will also occur

marcosps commented 2 years ago

It has been sometime since I opened the bug :)

I found a new pdf file which also shows the warning using the current flatpak version of Firefox: 91.0.1::

'Warning: Knockout groups not supported.'

22060_A1_01_Plans-1.pdf I also have the problem with this pdf. This issue seems to be open for almost 10 years now. Could we imagine that you'll be able to fix that at some point.

Exemple of one zone with your viewer : And with another one that can handle knockout groups :

Thanks for your work on that project anyway.
