openseadragon - v2.0.0

This is a major release with a number of breaking changes and deprecations (see below) and a major feature, true multi-image support:

http://openseadragon.github.io/examples/multi-image/

Please pay special attention to the breaking changes below if you had previously used the multi-image or multi-layer features of the previous versions of OpenSeadragon.

We've also added improved info on coordinate systems (even more important now with multi-image):

http://openseadragon.github.io/examples/viewport-coordinates/

...and published an SVG overlay plugin:

https://github.com/openseadragon/svg-overlay

Changelog:

True multi-image mode (#450)

- BREAKING CHANGE: Navigator no longer sends an open event when its viewer opens
- BREAKING CHANGE: Viewer.drawers and Viewer.drawersContainer no longer exist
- BREAKING CHANGE: A Viewer's Drawer and Viewport are now made once per Viewer and reused for every image that Viewer opens (rather than being recreated for every open); this means if you change Viewer options between opens, the behavior is different now.
- DEPRECATION: use Viewer.addTiledImage instead of Viewer.addLayer
- addTiledImage supports positioning config properties
- DEPRECATION: use World.getItemAt instead of Viewer.getLayerAtLevel

NOTE: This version has a number of breaking changes to the API, mostly in event handling. See below. - BREAKING CHANGE: All EventSource and MouseTracker event handler method signatures changed to 'handlerMethod(event)' where event == { eventSource, userData, ... } (#251) (Also fixes #23, #224, #239) - The new eventSource property in the event object replaces the old eventSource parameter that was passed to handler methods. - Where the event object duplicated the eventSource value, those properties have been removed. This affects the following events: - All Button events - 'button' property removed - All Viewer (Viewer, Drawer, Viewport) events - 'viewer' property removed - BREAKING CHANGE: Renamed EventHandler to EventSource (#225) - BREAKING CHANGE: Event names changed for consistency: changed to lower case, compound names hyphenated, and "on" prefixes removed (#226): - Viewer "animationstart" changed to "animation-start" - Viewer "animationfinish" changed to "animation-finish" - Button "onPress" changed to "press" - Button "onRelease" changed to "release" - Button "onClick" changed to "click" - Button "onEnter" changed to "enter" - Button "onExit" changed to "exit" - Button "onFocus" changed to "focus" - Button "onBlur" changed to "blur" - BREAKING CHANGE: Numerous improvements to fullPage/fullScreen (#256): - Retains zoom/pan position better when switching into and out of fullPage. - Retains scroll position when switching back out. - More resilient to styling variations on the page. - setFullPage no longer automatically engages fullScreen; there's now a separate setFullScreen. - 'fullpage' event is now 'full-page'. - The fullpage property of the 'full-page' event is now fullPage. - There is now a 'full-screen' event with a fullScreen property (true if it has gone to full screen). - There are now 'pre-full-page' and 'pre-full-screen' events that include a preventDefaultAction property you can set in your handler to cancel. They also have fullPage and fullScreen properties respectively, to indicate if they are going into or out of the mode. - BREAKING CHANGE: Removed the 'onPageChange' callback from the viewer options. Viewer.goToPage() now raises the 'page' event only (#285) - Major documentation improvements (#281) - MouseTracker now passes the original event objects to its handler methods (#23) - MouseTracker now supports an optional 'moveHandler' method for tracking mousemove events (#215) - Added stopHandler to MouseTracker. (#262) - Fixed: Element-relative mouse coordinates now correct if the element and/or page is scrolled (using new OpenSeadragon.getElementOffset() method) (#131) - Fixed: Pinch zoom event issue, regressive issue from previous event system changes (#244) - Added IIIF Image API 1.1 Tile Source (#230) - IIIF 1.0 now uses pixel based syntax (#249) - Fixed: Touch event issue where no canvas-click events were being raised (#240) - Check that zoom reference point is valid before using it in zoomTo and zoomBy (#247) - Added a number of easier coordinate conversion methods to viewport (#243) - Added the ability to create a viewer and start at a specified page (#252) - Fixed image resolve issue with collection mode (#255) - DOM events are now passed through as 'event.originalEvent' in viewer and button events where appropriate. (#257) Affects the following events: - Viewer: 'canvas-release', 'canvas-click', 'canvas-drag', 'canvas-scroll', 'container-enter', 'container-exit', 'container-release' - Button: 'enter', 'exit', 'press', 'release', 'focus', 'blur', 'click' - Fixed: IE 10 not reading DZI file correctly in certain circumstances (#218) - Added support for the 'wheel' DOM mousewheel event (#261) - Fix for non-canvas tile rendering at large size (#264) - Drawer now uses an HTML5 canvas element whenever it's available. Can be overridden with the Viewer.useCanvas option (#191) - Added a boolean preventDefaultAction property (default false) to the event object passed to MouseTracker handler methods. (#270) Implemented in the following MouseTracker subscribers: - Viewer.keyboardCommandArea.innerTracker.focusHandler: preventDefaultAction == true prevents scrolling viewer into view - Viewer.keyboardCommandArea.innerTracker.keyHandler: preventDefaultAction == true prevents viewer keyboard navigation - Viewer.innerTracker.clickHandler: preventDefaultAction == true prevents viewer zoom on click - Viewer.innerTracker.dragHandler: preventDefaultAction == true prevents viewer panning with mouse/touch - Viewer.innerTracker.scrollHandler: preventDefaultAction == true prevents viewer zooming on mousewheel/pinch - Fixed: IE8 error with custom buttons - "Object doesn't support this action" (#279) - Support IIIF servers that don't report tile dimensions (#286) - Added an autoResize option. Default is true. When set to false, the viewer takes no action when its container element is resized. (#291) - Added a static 'version' property to OpenSeadragon. Useful for plugins that require specific OpenSeadragon versions. (#292)
