Universal viewing of digital microscopy, whole slide imaging and digital pathology data.
pma-java is a Java wrapper library for PMA.start (http://www.free.pathomation.com), a universal viewer by Pathomation for whole slide imaging and microscopy.
YOU NEED TO HAVE PMA.START (OR PMA.CORE) RUNNING IN ORDER TO USE THIS LIBRARY. PMA-JAVA IS NOT A STAND-ALONE LIBRARY FOR WSI.
