[jira] [Commented] (PDFBOX-1462) Use file backed buffer for FlateFilter?

["Tilman Hausherr (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-1462?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14169726#comment-14169726 ] 

Tilman Hausherr commented on PDFBOX-1462:
-----------------------------------------

There's one risk with this: it won't work in an applet.

However Flatefilter has improved since you created the issue, see rev 1608537 and 1133726. Do you have a file that doesn't render (or whatever) with the standard settings?

> org.apache.pdfbox.filter.FlateFilter#decompress can cause OOM (depending on the size of the document and configured heap of course.) Consider using something like http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/io/FileBackedOutputStream.html to constraint memory pressure.
