Using open slide in Java Eclipse RCP based application...

Hello Benjamin,
Thanks for the help. I ran the java viewer and it worked well.
I have another question here. I see that the zoom/pan on the image is not smooth. I want to implement smooth animated zoom/pan in my application for these images. Is there a plan to support this feature?

Thank you for the help,

Hi Amay,

There is a complete Java binding to OpenSlide (called OpenSlide Java), 
but it is not documented nor very actively maintained.  I suggest you 
look through the source code for the org.openslide.OpenSlide class to 
get an idea of the API, and use the documentation for the OpenSlide C 
API to find out about OpenSlide's semantics.  If you're looking for an 
example, OpenSlide Java also includes a (somewhat buggy) demo viewer
