Hi all, As far as I understand there is currently no support for NDPI in OpenSlide, ref: http://lists.andrew.cmu.edu/pipermail/openslide-users/2011-August/000201.html I was wondering if anyone worked on a small command line converter using the NDPRead.h API http://imagetests.googlecode.com/svn/trunk/NDPRead.h Thanks for comments, -- Mathieu
