[Insight-developers] iterators in a reverse direction?

[Damion Shelton]

Hi...

Is there an easy way to iterate through an image in the "reverse" of the
normal direction? The code fragment:

for ( outIt.Begin(); !outIt.IsAtEnd(); ++outIt)

iterates forwards. Prior to looking at the documentation, I assumed that the
line:

for ( outIt.End(); !outIt.IsAtBegin(); --outIt)

would also be legal; the "--" operator is not defined, though. So, how do I
go about iterating backwards.

Thanks,
