[jira] [Comment Edited] (PDFBOX-4312) Signature is not getting
inserted into 00000 area
[ https://issues.apache.org/jira/browse/PDFBOX-4312?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16620995#comment-16620995 ]

------------------------------------------------------------------
So I was able to reproduce the effect, see attached files. This 1.8 source code
{code:java}
public void saveIncremental( String fileName ) throws IOException, COSVisitorException
{
saveIncremental(new BufferedInputStream(new FileInputStream(fileName)),
new BufferedOutputStream(new FileOutputStream(fileName, true)));
}
{code}
is suspicious, because one is writing on the same file than the one where one is writing, but I'm not sure if the writing start offset is really correct.

> Hi ,
> I want to sign pdf using signature in pkcs 7 format . I am converting pkcs 7 signature to byte array using Convert.FromBase64String method in .net . I am passing this byte array to sign method in signature interface which gets called after calling saveincremental. My byte array is inserting proper but the name of which signature is not shown when i open pdf. May be my byte conversion may not proper or something else i am doing wrong. please let me know.
