## Animation in papers…

So recently I was very excited about creating an animation from an ipe figure (see here). Interestingly, it is surprisingly easy to include such an animation in a latex document and see it in the resulting pdf. You would need to use acroread to see the animation (doesn’t work for okular, too bad).

Here is a minimal latex example:
 \documentclass{article} \usepackage{animate} \begin{document} \centerline{\animategraphics% [autoplay,autoresume,width=0.8\linewidth,% controls,loop,buttonsize=4em]% {2}{figs/animation_1}{0}{22}} Animation of algorithm -- you would need acrobat reader to see the animation - click the figure to make it start. \end{document} 
Here is the resulting pdf, and the complete source of this example with the ipe figure is here.

## Animating figures

So, generating an animated figure is surprisingly easy from a pdf file – every page turn into a frame, and one can easily set the delay between frames. One can easily generate such pdfs from ipe figures – especially when one draws a complicated figure with subfigures demonstrating an algorithm. The resulting animation demonstrates the algorithm much better than the static figure can. For example (and no, you are going to have no clue whats going on, for this you would have to read the paper, which I hope to post in a few days), see here.

So, the following works under linux using ImageMagic:
 convert -density 300 \ -delay 300 "file.pdf[0-3]" \ -delay 100 "file.pdf[4-21]" \ -delay 500 "file.pdf[22]" \ test.gif 
The delay parameter sets the time delay between frames (in 0.01 second units), and the “[0-3]” indicates what range of pages would be used. In the above, I put different delays between frames. The density parameter decides the resulting size of the output – larger number, results in a bigger image.

I hope this medium would be used more frequently – it definitely shows a potential to be useful.

## The latest referee report I got…

The results in this paper are known and obvious, on a new strange problem that the authors define but nobody cares about. Thus, one must conclude that the authors wrote the paper just because they like the clicking sounds made by the keyboard as they typed their paper. Also, all the words used in the paper can be found in a dictionary, so there is nothing new in this paper.

[I did rephrase the report a bit, and I am happy I helped making the conference more selective. Mark me as being amused.]
