Martin Mancuska updated PDFBOX-4028:
------------------------------------
Description:
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 (after 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}
