[jira] [Created] (PDFBOX-1241) Better handle of missing EOF at the
end of a file
Better handle of missing EOF at the end of a file
-------------------------------------------------
Key: PDFBOX-1241
URL: https://issues.apache.org/jira/browse/PDFBOX-1241
Project: PDFBox
Issue Type: Improvement
Components: Parsing, Text extraction
Affects Versions: 1.6.0
Environment: All platforms affected
Reporter: Ernst Eibensteiner
We came across PDF files that do not have a %%EOF at the end of the file.
This leads to the following execption:
c:\tmp> java -jar pdfbox-app-1.6.0.jar ExtractText -endPage 1 "On the Insert tab.pdf"
ExtractText failed with the following exception:
java.io.IOException: Error: Expected an integer type, actual=''
at org.apache.pdfbox.pdfparser.BaseParser.readInt(BaseParser.java:1384)
at org.apache.pdfbox.pdfparser.PDFParser.parseStartXref(PDFParser.java:6
63)
at org.apache.pdfbox.pdfparser.PDFParser.parseObject(PDFParser.java:464)
at org.apache.pdfbox.pdfparser.PDFParser.parse(PDFParser.java:184)
at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:1088)
at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:1053)
at org.apache.pdfbox.pdmodel.PDDocument.load(PDDocument.java:978)

at org.apache.pdfbox.ExtractText.main(ExtractText.java:76)
at org.apache.pdfbox.PDFBox.main(PDFBox.java:42)
While these PDFs are non-conforming, it'd be an improvement to allow them to be read and processed.

Summary: Better handle of missing offset at the end of a file (was: Better handle of missing EOF at the end of a file)
You're right. I've edited this issue to handle the missing offset (changed title and text) to correspond to the call stack -> 'Expected an integer type'

[jira] [Commented] (PDFBOX-1241) Better handle of missing EOF at

Maruan Sahyoun commented on PDFBOX-1241:
----------------------------------------
For the files you came across is only the %%EOF missing or also the offset. From my perspective these are issues which need to be dealt with separately.

Attachment: On the Insert tab.pdf
To reproduce the behaviour I have manually removed the last two lines. (Offset and %%EOF)
