Hi All,
Regarding PDFBOX-2301, and the use of scratch files: right now, each COSStream
uses one or two scratch files.
I recently ran into the problem on Linux where the max number of open files
allowed to the JVM by the OS was reached because of this.
Is there a plan around this?
Is it maybe that my use case is not expected?
I'm aware of that. The refactoring is still in progress. I expect to reduce the
number of open files.
My use case is:
Open PDDocument 1
Open PDDocument 2
for a few hundred times
import page 1 of PDDocument 1 into PDDocument 2 and overlay some stuff
ontop.
save PDDocument 2.
I have written a patch to use one single java.io.RandomAccessFile as a scratch
file per COSDocument, using pages in a doubly linked list to separate streams in
the same file. Would you be interested in adding this to PDFBox?
To use one file only led to problems when creating pdfs from scratch. It is
possible to write to 2 COSStreams at the same time which corrupts pdf.
Thanks,
Jesse
