All of the pieces you need are in iText - they are just LOW LEVEL pieces that you will need put together to make this work.
You'll need to start by reading and understanding the PDF standard (ISO 32000-1:2008) about exactly what an appearance stream is, how it is used, etc. Then you can use the pieces in iText to create one, connect it up, and voila. NOT trivial - but certainly well defined and doable. Leonard On 1/16/12 6:02 AM, "Rob" <rafri...@gmail.com> wrote: > >Paulo Soares-3 wrote >> >> Let's take the Line annotation.
