  • Very interesting link, but this kind of solution needs javascript programming :-( And should only solve my second case (button clicked)... – Lionel MANSUY Nov 7 '12 at 21:20

    Unfortunately, Javascript is seemingly the only way to achieve satisfactory interaction. (even worse only with AcroRead) – percusse Nov 7 '12 at 21:44
  • you can simply use \inlcudegraphics<1>{...} what should be on overlay <1> and so on. – user2478 Nov 8 '12 at 8:10

Here is a straightforward solution using a Widget Annotation (Push Button) according to the PDF specification. It displays different pictures depending on the current mouse position and its button state (out, roll-over, button-down).



\edef\normalappearance{\the\pdflastxform\space 0 R}
\edef\overappearance{\the\pdflastxform\space 0 R}
\edef\downappearance{\the\pdflastxform\space 0 R}


\hbox to \imgwd{\vbox to \imght{\vss%
  \pdfannot width \imgwd height \imght depth 0pt {
    /F 4
    /FT/Btn/Ff 65536
    /T (my dynamic image) % Widget name; must be unique
    /AP <<
      /N \normalappearance
      /R \overappearance
      /D \downappearance


In case of multiple Widget annotations, the Widget's names, as specified by the /T (...) entry, must be uniqe.

    For those who are interested, the method for producing the window recording is given here. – AlexG Nov 9 '12 at 9:34
  • @AlexG I'm in trouble with your code: it works nicely only for the first occurrence of a picture, not for the following ones... I've tried to replace the \Widget subtype by a \Link, but it does not work – Lionel MANSUY Jan 8 '13 at 16:53
  • @LionelMANSUY : The PDF created from the code example works properly only in Adobe Reader (as demonstrated by the animated screen recording). – AlexG Jan 9 '13 at 7:19
