>> origVal(xy+xy:[sin(y/6),sin(x/6)]*3);

"xy is a variable of type xy:2. That means it's a tuple with two

elements and it has the tag xy. You can create your own tuple with

two elements with [1,2], for example. It will have the type nil:2,

though, because nil is the default tag. If you want it to have the

tag xy you'll have two write xy:[1,2]. Then you can add that to the

variable xy, like xy+xy:[1,2].

One could write the above expression as

new_x = x+sin(y/6)*3;

new_y = y+sin(x/6)*3;

origValXY(new_x, new_y)

You might also want to read this explanation

It's a motivation for and description of the tagged tuple system which

I wrote before I implemented it (the tag conversion operator wasn't

implemented)."

So OrigVal(xy*xy:[cos(pi/2/Y*y),1]) means:

new_x = x*cos(pi/2/Y*y);

new_y = y*1;

origValXY(new_x, new_y);

First you should have Gimp-Python working

How to install GIMP on windows with Python support by David Gower :

- python (ActivePython select version 2.4 or later)
- NumPy (numpy-1.0.1.win32-py2.4.exe)
- GTK+ (gtk+-2.10.6-1-setup.zip)
- PyCairo ( pygtk on win32 / pygtk 2.8 / Python 2.4 (with pycairo support) )
- PyGTK+ ( pygtk on win32 / pygtk 2.8 / Python 2.4 (with pycairo support) )
- GIMP gimp-2.3.12-i586-setup.zip (verify that the 'gimp-python' extension is checked)
