[Insight-users] Visual Studio debugger visualizers for ITK

[Dženan Zukić]

I created the article<http://www.itk.org/Wiki/ITK_Debug_Visualizers_for_Visual_Studio>
and
put a link to it here <http://www.itk.org/Wiki/ITK#Users>.

I went through the iterator's code and fixed the dereference formula, it is
*(m_Buffer+m_Offset).

> Visual studio has support for custom visualization of user types in
> debugger (watch window and mouse hover)
> File C:\Program Files (x86)\Microsoft Visual Studio
> 10.0\Common7\Packages\Debugger\autoexp.dat controls how different
> datatypes are displayed. The file itself contains instructions on how
> to modify it.
>
> With VS2008 SP1 and newer you don't even have to modify that file, you
> can add environment variable _vcee_autoexp which points to your own
> file which will then be combined with the system one on the fly.

> itk::ImageRegion<*>{

>          size: $c.m_Size,
>          index: $c.m_Index
>       )
>    )
>    preview
>    (
>      #(
>          "R", $c.m_Size
>       )

> Two example screenshots are attached:

> buffer: itk::Image with underlying buffer expanded (limited to first

> Some of this could probably be automated by changing the source code

> Also, we should probably put this file into the wiki. Is
> http://www.itk.org/Wiki/ITK the right place to put the link?
