Tilman Hausherr commented on PDFBOX-4312:
-----------------------------------------
This is being done in {{COSStandardOutputStream.setPos()}}. This works only if
the output stream passed is a FileOutputStream. The best would be that you look
into it with a debugger, if possible.
Sadly you didn't attach the new code so I can't check if you did use the code
from September 19th.
Lets assume you did.
Then maybe {{COSStandardOutputStream.setPos()}} isn't accessed (that was the
original bug), or it does nothing.
To test whether setting the position in a FileOutputStream works in .net, try a
code like this in .net:
{code}
FileOutputStream fos = new FileOutputStream("deleteme.txt");
byte buf[] = new byte[25000];
fos.write(buf);
FileChannel fileChannel = fos.getChannel();
fileChannel.position(5000);
fos.write("Hello world".getBytes());
fos.close();
FileInputStream fis = new FileInputStream("deleteme.txt");
int by;
int pos = 0;
while ((by = fis.read()) != -1)
{
if (by == 'H')
{
System.out.println("pos = " + pos);
break;
}
++pos;
}
fis.close();
{code}
The output should be "pos = 5000". If not, then positioning doesn't work on
.net. In that case you should us PDFBox 2.0.12, which uses a different strategy.

> 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.
