zoomify 1.2.1

A Dart package to display and manipulate Zoomified images. Zooming and panning with gestures, mouse and keyboard

1.2.1

• bugfixes and optimizations
• added panButtonOffset parameter to the constructor (default = 100) and changed the default direction of button pan movement

1.2.0

• added code for Deep Zoom Image (DZI) images
• further improved transitioning over zoom levels to prevent flashing
• added a single row/col of tiles around the edges to prevent 'black' tiles when panning
• fixed a bug in the controller

1.1.1

• improved image display when transitioning from one tile leyer to the next (higer or lower) layer

1.1.0

• Added buttonAxis parameter to the constructor (default = Axis.vertical)
• Added buttonOrderReversed parameter to the constructor (default = false)

1.0.9

• Added showPanButtons and showResetButton parameters to the constructor (both default false)
• Changed zoomButtonPosition and zoomButtonColor to buttonPosition and buttonColor (breaking)
• Clamped zoomLevel, zoomCenter and panTo inputs to acceptable values
• Added an extra value in the onTap callback function. Now (imageOffset, windowOffset) (breaking)
• Code optimization and bug fixes

1.0.8

• Added parameter 'interactive' (default = true). If set to false, you can/should add your own keyboard/mouse/gesture detector on top of the zoomify widget, or use the controller to interact with the image.
• Added parameter 'pantTo: Offset' to controller.(animate)PanAndZoom function. Moves the given point, relative to the original max image, to the center of the window
• Added parameter 'fitImage' (default = true). If set to false, allows the image to become smaller then the winde

1.0.7

• Breaking: changed parameters in onImageReady to (Size maxImageSize, int zoomLevels)
• Breaking: changed parameters in onChange to (double zoomLevel, Offset offset, Size currentImageSize)
• Added controller get functions getZoomLevel, getOffset and getCurrentImageSize
• Added onTap callback function, returning the tap offset from the top-left corner of the non-zoomed-in image
• Code optimizations and bugfixes

1.0.6

• Added a decent controller for programmatically zooming, panning and reset (see example). The previous way of working (directly calling the state functions) will be removed in the next version.)
• Added an optional sync parameter (default false). Setting it to true will cause the onChange callback function to be triggered each animation frame. This allows for synchronous zooming / panning something else in your app (for example a flutter_map or another zoomify picture in sync with the zoomify widget).

1.0.5

• BREAKING CHANGE: in the (animate)ZoomAndPan function the scaleDelta parameter has been removed and replaced by the zoomLevel parameter, i. e. you have to supply the new zoom level instead of a delta. The first parameter that is returned in the onImageReady callback is the maximum zoomlevel. Zoomlevel 1 fits the whole picture within a single 256x256 tile (TileGroup0/0-0-0.jpg). However, you cannot zoom out smaller than the size of the widget.

1.0.4

• Added zoomAndPan, animateZoomAndPan and reset functions, to allow for programmatically zoom, pan or reset the image (See the example how to use these functions)
• Added animation parameters duration and curve
• bugfixes

1.0.3

• Improved(?) animations
• Added callback function onImageReady and onChange

1.0.2

• Used package 'path' to ensure proper uri creation
• Added basic animation when zooming and panning using keyboard

1.0.1

• Minor bug fixes
• Added android, ios, windows, mac, linux and web support in example (tested android, windows and web)

1.0.0

• Initial release
• Minor bug fixes

0.0.1

Initial (test) release.
