[jira] [Commented] (PDFBOX-4399) Disabled optional content groups are rendered

["Andreas Lehmkühler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-4399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16736225#comment-16736225 ] 

Andreas Lehmkühler commented on PDFBOX-4399:
--------------------------------------------

Sorry for the delay. I had a look and it looks good to me. I'm not sure if it is always a good idea to omit the content if there aren't any properties defining the OCG, but maybe that's simply because I didn't understood every bit of that part of the spec (the clipping stuff etc.) As long as there aren't any regressions we are fine with the current approach.

Maybe one could think about adding that stuff to the text extraction as well to suppress optional text. Does this make sense?
