I have copied the code there using \pdfannot, and I have tried inserting an annotation using \pdfobject but can get neither to work. I am using Adobe Acrobat Reader 4.05 and doing the whole lot on WinNT. Ideally, I would like to be able to put an annotation next to a graphic, say, with the copyright information contained within it. Has anyone done this? If so, could you give me an example?

This is what I do (takes two arguments title, and text), can't quite
remember how it works or where I got it from.


\makeatletter
\newcommand{\annotate}[2][]{%
  \pdfstringdef\x at title{#1}%
  \edef\r{\string\r}%
  \pdfstringdef\x at contents{#2}%
  \pdfannot
  width \linewidth
  height 3\baselineskip
  depth 0pt
  {
    /Subtype /Text
    /T (\x at title)
    /Contents (\x at contents)
    }%
  }
\makeatother
