[Insight-users] What does this error mean?

[Mathieu Malaterre]

Bill,
	Please note that is application is obsolete and is removed from the 
actual toolkit.

	See:
http://www.itk.org/pipermail/insight-users/2003-March/002805.html
and
http://www.itk.org/pipermail/insight-users/2003-February/002660.html

Quoting Luis:
[The PNGImageReadWrite was an attempt to
experiment with the option of writing a volume
as a series of PNG images. Unfortunately this
functionality is not completly implemented
yet. So this particular application is not
working at this point. It is actually in the
list of applications to be removed before the
relase 1.2.]

	If you are looking for a mechanism for reading
and writing volumes, the best formats at this
point are: MetaImage, Analyze, Gipl, Stimulate and VTK.
