Introduction

In this tutorial we learn how to install iipsrv on CentOS 7.

What is iipsrv

Light-weight streaming client-server system for the web-based viewing and zooming of ultra high-resolution images. It is designed to be bandwidth and memory efficient and usable even over a slow internet connection. The system can handle both 8 and 16 bit images, CIELAB colorimetric images and scientific imagery such as multispectral images. The fast streaming is tile-based meaning the client only needs to download the portion of the whole image that is visible on the screen of the user at their current viewing resolution and not the entire image. This makes it possible to view, navigate and zoom in real-time around multi-gigapixel size images that would be impossible to download and manipulate on the local machine. It also makes the system very scalable as the number of image tile downloads will remain the same regardless of the size of the source image. In addition, to reduce the bandwidth necessary even further, the tiles sent back are dynamically JPEG compressed with a level of compression that can be optimized for the available bandwidth by the client.
