Summary: Big Pdf parsing to text - Out of memory
Key: PDFBOX-3284
URL: https://issues.apache.org/jira/browse/PDFBOX-3284
Project: PDFBox
Issue Type: Bug
Components: Parsing
Affects Versions: 2.0.0, 1.8.11, 1.8.10
Reporter: Nicolas Daniels
I'm trying to parse a quite big PDF (26MB) and transform it to text, however
I'm facing a huge memory consumption leading to out of memory error. Running my
test with -Xmx768M will always fail. I've to increase to 1500 GB to make it
work.
The resulting text is only 3MB so I don't understand why it is taking so much
memory.
The pdf can be found
[here|https://www2.swift.com/uhbonline/books/public/en_uk/clr_3_0_stdsmx_msg_def_rpt_sch/sr2015_mx_clearing_3dot0_mdr2_solution.pdf]
My code:
{code:title=Test.java|borderStyle=solid}
@Test
public void testParsePdf_Content_Memory() throws Exception {
{
InputStream inputStream =
getClass().getResourceAsStream("c:/tmp/sr2015_mx_clearing_3dot0_mdr2_solution.pdf");
try {
StringWriter writer = new StringWriter();
FileWriter fileWriter = new FileWriter(new
File("c:/tmp/test.txt"));
PDFTextStripper pdfTextStripper = new PDFTextStripper();
pdfTextStripper.writeText(PDDocument.load(inputStream),
fileWriter);
fileWriter.close();
} finally {
inputStream.close();
}
}
{code}
