Subject [jira] [Commented] (PDFBOX-4697) Reduce memory footprint when flattening
Date Sun, 24 Nov 2019 16:24:00 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4697?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16981128#comment-16981128

Tilman Hausherr commented on PDFBOX-4697:
-----------------------------------------

Should I revert? I'd do it if we lose some other feature in Adobe or in other tools (e.g.
editing?) that I don't know about. The reason I did this in the first place was that message
on the user mailing list about the memory usage when having many tiny content streams, even
if that one wasn't about flattening.

> Flattening produces many small extra content streams. We can make one single content
stream from these instead, because each content streams means one "page" of our memory management
is used.
