JVSview JPEG2000 viewer application

About | Features | Screenshots | Download | Documentation


JVSview is a JPEG2000 virtual slide viewer that works identically both in local storage and JPIP-based virtual slide viewing. Viewing in JVSview is based on on-demand image processing, which means that only the current requested view of the virtual slide is loaded into the computer's memory. Virtual slide image files can reside in a local storage (e.g., a hard drive or a CD/DVD), or in a remote storage which is accessed via the internet.

JVSview is a client application, which can be used alone for viewing of JPEG2000 compressed virtual slides from a local storage. When using JVSview in a network environment, the JVSserv server application is required.

JVSview is free software for non-commercial purposes, and can be redistributed freely. It is written in C++ and is based on the Kakadu JPEG2000 framework. JVSview can be run on a Windows 95/98/NT4/2000/XP/Vista environments with 32-bit or 64-bit architecture.
