[jira] [Closed] (PDFBOX-4243) DataFormatException: "invalid stored
block lengths" in FlateFilter
[ https://issues.apache.org/jira/browse/PDFBOX-4243?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tilman Hausherr closed PDFBOX-4243.
-----------------------------------
Resolution: Won't Fix
I'll do it. The best is to have the text extraction run separately for each page. This way you'll only lose one page and get all the rest. (Apache Tika can do this too).
