[jira] [Updated] (PDFBOX-1798) Performance problem with
PDDocument.saveIncremental (when signing document)
[ https://issues.apache.org/jira/browse/PDFBOX-1798?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Dmytro Karimov updated PDFBOX-1798:
-----------------------------------
Description:
Performance problem in class COSWriter:
Constructor of COSWriter takes 2 args:
COSWriter(OutputStream os, FileInputStream is)
method saveIncremental in class PDDocument:
saveIncremental(FileInputStream input, OutputStream output)
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.
