Graphics, Figures & Tables ⇒ Torn paper tearout example

[Erik_Schiegg]

Hi folks, happy easter,

I found this beautiful example making a fractal paper tear out text box, but I can't get it to work, when I open it in overleaf

http://www.texample.net/tikz/examples/torn-paper/
The code looks like this, please open the original from the link

This example is similar to: http://texample.net/tikz/examples/framed-tikz/
Fractal decorations are used to achieve a torn paper effect.
The bottom of one piece matched the top of the next one.
This is done by resetting the random seed before drawing each border.
However, you get the "same" random border in all your fragments,
which is not nice. You want randomness in each new bottom border,
but exactly the same randomness in the next top border. In order to get this,
you need a global counter which is increased in each "paper fragment",
and which is used as seed for the bottom border.
It is neccesary to use \pgfextra to be able of setting the seed in the middle
of the path (i.e: between top and bottom borders).
In addition, there is the problem that both paths (top and bottom) have to be
drawn in the same direction in order to get the same contour. 
In order to fill the piece of paper with a background, it is not possible
to draw both top and bottom borders in the same direction (eg. left to right).
So the solution involves drawing one piece of paper visiting its corners in
clockwise direction, and the following one in counter-clockwise direction.
I use the counter mathseed and draw in one direction or the other based

Although there is a special overleaf link...
As I am still quite a greenLaTeXhorn, I would be glad for a helping hand getting this example to work. Thank you.

Hi Erik,

welcome to the forum!

It seems that TikZ key has been renamed: use shading=bilinear interpolation instead of shade=bilinear interpolation.

And where can I look up the actual keys of packages on my own?

[Stefan Kottwitz]

Yes, indeed you just need to change the single word.

I tested also on Overleaf, the code then works for me. The second error was just a consequence: since the first error was in the paper style, it could not be created, and the compiler continued, so later it was not able to find a paper style. Just fix this single word.

Thank you Stefan, I got it to work in the VerbTeX editor,
overleaf is not working well from a tablet, no copy paste for example! I have to work the overleaf handling out, connecting a keyboard... or repair my regular laptop, broken DC connecter, no big deal...

You helped me like a Boss!
