[Insight-users] Just a Question: Is there any utility other than CMake that can be used to build ITK ?

Hi all,
Although CMake is developed as a part of ITK project, I am just curious to know if there is any other utility similar to CMake, which can be used to build ITK ?
Thanks,
Neha

Hi Neha,
Unfortunately not all applications in the InsightApplications
module are taking full advantage of the factory mechanism.
For example, GaussianFilter was restricted to use MetaImage.
In recent weeks, there has been an explosion of new file
formats in the toolkit. So, we have to revisit the applications
and make sure they are taking advantage of the new possibilities.
The GaussianFilter application has been modified now to accept
any of the default file formats registered in the factory
mechanism.
Please try your image with the "MetaImageViewer", this viewer
should be able to read (in addition to MetaImage), any of the
default file formats. Note that this application will display
a window and requires you to click on the window in order to
force a first refresh. Your file should work ok in this viewer.
Note that RAW is *not* a default format. The reason is that it
is actually not a format at all. In order to read RAW files you
have to hardcode the parameters of the file. That practice defeats
the whole purpose of the flexibility provided by the IO factory
mechanism.
Please let us know if you find any problems,
Thanks
Luis
