Project Summary

OpenZoom is an Open Source SDK for Multiscale Images and Zoomable User Interfaces (ZUI)MissionPromote and support the development of Zoomable User Interfaces with multiscale images on the web with frameworks, tools and real-world applications.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. The core concepts such as Scene, Viewport, Transformers, Constraints, Controllers and Descriptors are not platform specific and user contributed implementations of the core SDK for other platforms are welcome.

Personally, the OpenZoom SDK is my exploration of novel ideas and different approaches in architecture and implementation for Zoomable User Interfaces (ZUIs) and Multiscale Images for the Flash Platform.

ApplicationsHighly customized multiscale image viewers for Deep Zoom, Zoomify, OpenZoom and custom image sources (IMultiScaleImageDescriptor). GIS/Mapping Business Applications Scientific & Medical Imaging Data Visualization Presentation Software Dashboards What You Can Build With ItOpenZoom was not born as a framework. Its core design elements come from architectural patterns that have been extracted from my work with ZUIs and multiscale image applications on the Flash platform such as the tandem project. Although I explore different software architectures and design patterns, I try to stay pragmatic and take advantage of the benefits that the platform, in this case Flash or Flex, has to offer. Keeping the codebase small and approachable is a high priority. The OpenZoom SDK reflects my current knowledge and experience from building ZUIs and multiscale image applications with Flash and Flex.

tandem is a real-world example of what you can do with OpenZoom. It is a proof of concept for a new paradigm of navigating and exploring Flickr. tandem was built a couple of months ago and the current state of the SDK is much more advanced.

OpenZoom SDK ComponentsMultiScaleImageThe MultiScaleImage component for Flash and Flex supports single Deep Zoom, Zoomify, OpenZoom or custom multiscale images.

DeepZoomContainerThe DeepZoomContainer component for Flex supports single Deep Zoom images (DZI) and Deep Zoom collections (DZC).

As the entire SDK is still in its incubation phase, the lastest versions of those components are best obtained from the source code repository.

OpenZoom TangoA custom viewer and templates for the Adobe Photoshop CS3/CS4 Zoomify Export feature built with the OpenZoom SDK.

Download: OpenZoom Tango

FeaturesFullscreen support Mouse navigation (click to zoom in and Shift-click to zoom out) Mouse wheel support in all browsers (scroll to zoom) Keyboard navigation (Pan with W, S, A, D or arrow keys, Zoom with + / – or I and O, Show All with H, Fullscreen with F.) Context Menu support Standards-compliant Flash embed through SWFObject 6 templates — Normal / Fullscreen: black, gray and white. Just 40KB — 100% Flash, no Flex. 100% Open Source. No branding. Multiscale Image Descriptor FrameworkThe OpenZoom project features a flexible architecture for describing multiscale images. Implementations for describing existing formats such as Microsoft Deep Zoom, Zoomify and the custom OpenZoom Image Format are provided. These implementations have gone through fair amount of real-world testing and might be great starting point for an implementation to other platforms.
