--------------------------------------
Summary: Performance problem with PDDocument.saveIncremental (when
signing document)
Key: PDFBOX-1798
URL: https://issues.apache.org/jira/browse/PDFBOX-1798
Project: PDFBox
Issue Type: Improvement
Components: PDModel, Signing
Affects Versions: 1.8.3, 2.0.0
Reporter: Dmytro Karimov
Fix For: 1.8.4
Performance problem in class COSWriter:
Constructor of COSWriter takes 2 args:
{code}
COSWriter(OutputStream os, FileInputStream is)
{code}
method saveIncremental in class PDDocument:
{code}
saveIncremental(FileInputStream input, OutputStream output)
{code}
It create COSWriter with this args. If I pass FileInputStream into
saveIncremental then signing the document goes quite a long time.
If you pass BufferedInputStream, the signing speed is increases. But alas, this
is not possible, because the parameters of the method _saveIncremental_ does
not allow to do this.
