Open Source Framework for Multi-Scale Images and ZUI
OpenZoom is an Open Source Framework for Multi-Scale Images and Zoomable User Interfaces (ZUI). The OpenZoom core framework is built on top of the Adobe Flash Platform and provides custom components that can be used either in Flash or Flex.
MultiScaleImage is a component that built on top of the OpenZoom framework.There are three core concepts of the MultiScaleImage, namely transformers, controllers and constraints.
The transformer controls the animation of the viewport. Controllers are the glue between user input and viewport control. The constraint controls what states the viewport can reach. Don’t want people to zoom out too much? Just add a ZoomConstraint and set minimum and maximum zoom.
