the Modified() method was exactly what I was looking for.. I didn't look far enough through the inherited methods; my bad.

I know it won't work properly with mixed sized images, but I still think it's an improvement to the SCIFIOImageIO, so I submitted a patch<http://review.source.kitware.com/#/c/11936/>(which also fixes itkSCIFIOImageIO::Write, RGB reading, and other things..) I admit I'm not entirely sure how much work it would be to create a SCIFIO IO for the video framework. So I created an issue for it<https://github.com/scifio/scifio-imageio/issues/3>in our github repo for now. - Mark On Tue, Jul 9, 2013 at 12:19 PM, Matt McCormick <[email protected]>wrote: > Hi Mark, > > There should be no modification to itk::ImageIOBase itself, only the > addition of a SCIFIOImageIO::SetSeriesIndex method. > > itk::ImageFileReader is not aware of modifications that occur to the > ImageIO class, so Modified() must be called on the ImageFilterReader > after SetSeriesIndex is called on the ImageIO.
