Counting pages of a PDF gives OutOfMemoryError
-----------------------------------------------
Key: PDFBOX-1226
URL: https://issues.apache.org/jira/browse/PDFBOX-1226
Project: PDFBox
Issue Type: Bug
Components: PDFReader
Affects Versions: 1.6.0
Environment: Windows 7 / Windows XP
Reporter: Anca Zapuc
I have a pdf ( 397 MB) and I am trying to count the pages.
I am able to open the PDF with AdobeReader 9, but no with FoxitReader.
Code:
PDDocument doc = null;
File temp = null;
RandomAccessFile rand = null;
int nr = 0;
try {
//create a temporary file needed by the PDFBox when dealing
with PDFs really really large
temp = new File("e:/temp.tmp");
//using random access file needed for PDF really large
rand = new RandomAccessFile(temp,"rw");
doc = PDDocument.load(file,rand);
nr = doc.getNumberOfPages();
}catch(Exception e){
e.printStackTrace();
}
Got following exception:
org.apache.pdfbox.exceptions.WrappedIOException
