OpenSlide+ITK can't load image successfully

[yuzhou at andrew.cmu.edu]

Hi folks,

I am developing a pathology image analysis tool using ITK and Qt. In my
program, I tried to use OpenSlide to load big svs/TIFF images. I added
ITKOpenSlideIO (downloaded from
https://github.com/InsightSoftwareConsortium/ITKOpenSlideIO) to ITK source
code and built it successfully. But in my program when I tried to set
itk::ImageIO to ITKOpenSlideIO, it cannot be set correctly. This
ITKOpenSlideIO module has not been updated for three years so I am not
sure if it can be used successfully. Does anyone known about this module
or have experience in loading whole slide images using OpenSlide in ITK?
Could you please give me some suggestions on it? Thank you all!
