             Summary: SaveIncremental on same opened file
                 Key: PDFBOX-4028
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4028
             Project: PDFBox
          Issue Type: Bug
          Components: Writing
    Affects Versions: 2.0.8
            Reporter: Martin Mancuska


The incremental save does not work correctly if it is done on the same opened document. It produces corrupted file. The save incremental should append changes at the end of file (afer last origin EOF).
Newly saved file contains changes also in the middle of the file not only at the end. Changes in the middle of file contains zeroed bytes or garbage. 

Tested with the latest stable version of PDFBox 2.0.8.
 
Sample code:

{code:java}
String fileName = "/path/to/document.pdf";
PDDocument doc = PDDocument.load((new File(fileName));
...
document changes
...
try ( OutputStream outStream = new FileOutputStream(fileName)) {
	doc.saveIcremental(outStream);
}
catch ....
...
{code}
