I've never used Mathematica so that it's pretty difficult for me to
understand the following lines of code which I guess do the main job of
distorting the image

xkcdDistort[p_] := Module[{r, ix, iy},
   r = ImagePad[Rasterize@p, 10, Padding -> White];
   {ix, iy} =
    Table[RandomImage[{-1, 1}, ImageDimensions@r]~ImageConvolve~
      GaussianMatrix[10], {2}];
   ImagePad[ImageTransformation[r,
     # + 15 {ImageValue[ix, #], ImageValue[iy, #]} &, DataRange ->
Full], -5]];


Is there somebody there that can describe this algorithm with words
(English or Python ;-)) ?

I feel like the key point is about adressing the rasterized plot image
"r" with some slightly randomized indices "ix" and "iy". However, I
really don't get the step that generates these indices.

Best,
Pierre

Hi,

Is it just my web browser getting crazy or is there a real issue with
the ML archive on sourceforge:
http://sourceforge.net/mailarchive/forum.php?forum_name=matplotlib-users

I only see email records until July 16th 2012 !!

If there is another ML archive website in better shape, it would be
worth updating the link on matplotlib.org front page
("Documentation/need help?" section)

Best,
Pierre

This would make for an awesome couple of examples for the gallery, the
mathematica solutions look really pretty cool:

The matlab and R version not quite so much, still for reference:

Any takers?

Thank you so much, Anthony. After weighing the options, I decided to go for
Tkinter. The major reason for this is portability. BTW, I checked out your
website. Those screenshots are quite impressive. :-)
