Object offsets should be of type long + PATCH
---------------------------------------------
Key: PDFBOX-1196
URL: https://issues.apache.org/jira/browse/PDFBOX-1196
Project: PDFBox
Issue Type: Improvement
Components: Parsing
Affects Versions: 1.6.0
Reporter: Timo Boehme
Priority: Minor
Currently object offsets are stored as integer (32 bit). However the PDF
specification does not limit a PDF document to 2GB. The only restriction is the
XREF table which supports 10 digit values for object offsets. Thus we could
have offsets >2GB (<10GB). The attached patch changes all locations (as far as
I could find them) dealing with object offsets to long type.
Since this is a rather small change which should not have greater
performance/space impact I recommend to include it. Otherwise we would have to
include checks that the parsed file is smaller then Integer.MAX_VALUE.
