[jira] [Commented] (PDFBOX-4297) Allow to space efficiently analyse
large PDFs
[ https://issues.apache.org/jira/browse/PDFBOX-4297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16589087#comment-16589087 ]
Tilman Hausherr commented on PDFBOX-4297:
-----------------------------------------
I think that what you want is parsing on demand. If this would exist, then creating 1+2+3 would just be a tool like many others.

> Key: PDFBOX-4297
> URL: https://issues.apache.org/jira/browse/PDFBOX-4297
> Project: PDFBox
> Issue Type: Improvement
> Reporter: Ralf Hauser
> Priority: Major
>
> Assume you get a 300+MB large pdf and need to know
> 1) the file names of embedded files if any
> 2) whether it is encrypted (symmetric or asymmetric)
> 3) certification level (and whether it is signed)
> This should not use more than 5 MB (extra) memory
>
> P.S.: seems to an exampe of https://pdfbox.apache.org/ideas.html "Handle large PDF files"
