To set the spacing of the output image using the input image, you can do such thing :

spacing[0] does not work for instance :
TypeError: ‘itkVectorD3Ptr’ object does not support indexing

Do you know how to do this ?

I use"itk_image.SetSpacing(1.5,1.5,2.0)" to define the space of a ITK image, but failed. Can you give a help? many thanks~ xh hi Paul,

I use”itk_image.SetSpacing(1.5,1.5,2.0)” to define the space of a ITK image, but failed.

This should automatically set everything up so CMake can find everything. To install the dev package just type in the following: <code>sudo apt-get install libinsighttoolkit-dev</code> To be able to build your own ITK projects, you need the dev package.

I'm using the python ITK+VTK setup to quickly test and experiment. I then write it in C++ for the main program. Thanks for the packages, as the standard distro packages don't quite cut it!

A real beginner here I'm afraid. I installed ITK via your repository. I'm now trying to run the first program from the ITK documentation. The documentation says I must specify the directory where ITK is built and when I try and run the Cmake file I get "ITK not found". Can you let me know what directory I should use? Thanks Ben Hi. A real beginner here I’m afraid. I installed ITK via your repository.

I’m now trying to run the first program from the ITK documentation.

The documentation says I must specify the directory where ITK is built and when I try and run the Cmake file I get “ITK not found”.

Can you let me know what directory I should use?

Thanks

Ben

The reason itk does not work in jaunty is because of the switch from python 2.5 to 2.6. Python2.5 should still be installed on you system, and if you start python2.5 instead of python, the itk packages are available. To get itk working in python 2.6 is a simple fix, but I would recommend just waiting for me to release packages for jaunty. I am putting together the Jaunty packages at the moment.
