pgf missed package

Postby Spider » Wed Jan 01, 2014 1:32 pm

Hi all,
I am working on a presentation using beamer and I would like to display a series of images with a specified delay. I found the following code:
  1. \frame{
  2. \only<1>{
  3. \begin{centering}
  4. \pgfimage[scale=.5]{fish1.jpg}
  5. \par
  6. \end{centering}}
  7.  
  8. \transduration<2>{5}
  9.  
  10. \only<2>{
  11. \begin{centering}
  12. \pgfimage[scale=.5cm]{fish2.jpg}
  13. \par
  14. \end{centering}}
  15.  
  16. \transduration<3>{5}
  17.  
  18. \only<3>{
  19. \begin{centering}
  20. \pgfimage[scale=.5cm]{fish3.jpg}
  21. \par
  22. \end{centering}}
  23. }

I got a message error that I missed a required package.
Can anyone tell me the suitable package for that?
Thank you!
