[Insight-users] Python ITK, minimum and maximum computation : Get a fish and learn to fish

[Gaetan Lehmann]

Hi,

WrapITK comes with some functions to make common task like this one easier:

1> import itk

2> reader =  
itk.ImageFileReader.IUC3.New(FileName="/home/glehmann/analyse/granex/emb-01ZOOM.tif")

3> itk.range(reader)
3> (0, 255)


If you have applied the optional patches, you can use the "print" command  
on an ITK object. Without the optional patch, you can use itk.echo()  
function (print is a reserved word in python)

4> print reader
<snip>

5> itk.echo(reader)
<snip>


For more info, with ipython, the class name followed by "?" will display  
you the man page of the class

6> itk.ImageFileReader?

Or you can found more doc in the ITK doxygen pages:  
http://www.itk.org/Doxygen/html/hierarchy.html
