Wow.
How so, wow?
So, shouldn’t this code be removed from your library, as it seems to be useless and bug-inducing?
See the attached example. Are you saying the code is useless? If I have a file ocg.pdf, then I can use the code to get info about PdfLayers and I can apply changes. The file ocg.pdf is changed into ocg_altered.pdf without throwing an exception.
As for paying for a custom solution…we’ll just generate two different files and switch the filenames….
That's fine by me if that works for you, but there's no reason for you to say that iText is useless.
