This page describes the launching and basic utilisation of Pink's Python front-end.
If you have succeded with Compiling Pink with CMake, there is a script file 'pink.sh' generated on the top of your Pink build directory. You can invoke the Python interpreter by typing
./pink.sh
If you have also installed Pink after the compilation, you can get the same environment by launching the Python interpreter
ipython
you should get the following prompt:
Python 2.6.2 (r262:71600, Oct 28 2010, 20:54:41) Type "copyright", "credits" or "license" for more information. IPython 0.10 -- An enhanced Interactive Python. ? -> Introduction and overview of IPython's features. %quickref -> Quick reference. help -> Python's own help system. object? -> Details about 'object'. ?object also works, ?? prints more. In [1]:
This is a standard Python interpreter. The script sets up the necessary directories so that the interpreter would find the Pink library. The ultimate test of a successfull compilation is the importing of the library in Python:
In [1]: import pink In [2]:
The [2] promtline indicates that the import have succeded. You can now list the available functions:

The operator can be called the standard Python call:
I=pink.cpp.char_image([10,10]) inverted_image = pink.cpp.inverse(I)
You can look at the documentation of a function (operator) by calling the help function:
help(pink.cpp.geoeros)
The help looks like this:
Help on built-in function geoeros:
geoeros(...)
geoeros( (char_image)G image, (char_image)F image, (int)connexity [, (int)number of iterations=-1]) -> char_image :
geoeros.c
geodesic (grayscale or binary) erosion
Usage: geoeros g.pgm f.pgm connex niter out.pgm
Description:
Geodesic erosion of g.pgm over f.pgm.
Let G and F be the two input images. If G is not over F, then
G is replaced initially by max(G,F).
The structuring element is specified by the value of the parameter connex,
which can be one of the following ones: 4, 8 in 2d, or 6, 18, 26 in 3d.
The parameter niter sets the number of iterations. If niter = -1,
then the iterations continue until stability.
Types supported: byte 2d, byte 3d.

C++ signature :
pink::ujoi<unsigned char> geoeros(pink::ujoi<unsigned char>,pink::ujoi<unsigned char>,int [,int=-1])
The documentation contains three parts. The signature of the python function
geoeros( (char_image)G image, (char_image)F image, (int)connexity [, (int)number of iterations=-1]) -> char_image : geoeros.c
The description of the usage and the c++ signature of the operator:
