Abstract

For web-browser-based scalable display systems, we recently presented the Virtual Display Area (VDA) [1] concept, which unifies different display resolutions and tiling by abstracting the physical pixel spaces into a single software display. Web browsers, however, are generally not designed for handling images of large size, even though ultra-high-resolution images emerge especially in the HPC and big data communities. We thus present an approach to handle ultra-high-resolution images for web-based scalable display systems while keeping the principle of the VDA to achieve both the efficiency of operations and the simplicity of software design. We show the advantage of our approach by comparing its performance to that of SAGE2, which is the de facto standard web-based scalable display system.
