Re: [iText-questions] Page By Page Rendering

[Bharath]

Found a solution for the same. when we use BYTEARRAYOUTPUTSTREAM  it is holding the document in Memory. But changed it by writing a CustomBufferedOutputStream extended from BufferedOutputStream. Additionally exposed the count method of the same. Now for the file size used the count method. Sample file is attached.Let me know of your thoughts. This stopped the application from holding up larger memory since the output is buffered.
Please let me know of your thoughts on the same

Thanks for the detailed explanation. So My feeling that the BYTEARRAYOUTPUTSTREAM is what is causing the problem is TRUE. The outputstream need to be Byte Array since the application runs on IE only. :(

 

Is there any other big object in the PDF renderer other than the BYTEARRAYOUTPUTSTREAM that can be so huge  which I can free without harming anything?

 

Now I liked the FileOutputStream option but need to discuss with our customers on this before implementing the same if that seems to be the only go.

If you write to response.getOutputStream() directly, the problem won't
occur.
I use this solution in a controlled environment: i.e. the company I work
for can
force the users to use Firefox, Mozilla or Netscape only.
The ByteArrayOutputStream solution is only used to avoid problems with MSIE.

The question is wrong.
You can create multiple documents by using new Document,
but what OutputStream are you going to use?

You could write the complete PDF to a FileOutputStream
and serve this file to the end-user. Once the file is read to
the ServletOutputStream, you could delete the file.
