How do we use a PdfWriter of iTextSharp?

Question

If you do a google search you will find some code samples more or less like this:

PdfWriter writer = PdfWriter.GetInstance(document, myIoStream);

And interestingly, most of the code samples don't use the writer object at all. So, what's the point of getting that handle? Thank you!

You can do just PdfWriter.getInstance(document, myIoStream);

this will "create" the document using the stream.

When using PdfWriter writer = PdfWriter.GetInstance(document, myIoStream);

we can use a lot of methods like AddAnnotation() that will be merged with the document or also call .DirectContent to add images, etc.

Hope it helps.
