• Pageflip effect (Captain Obvious).
• Runs in any browser, on any device.
• File size just 76KB gzipped.
• Hardback option for every page, as well as a hardcover option for the containing book, automatically making the first and last pages hardback.

• Methods allowing automatically flipping through the pages of a book ( gotopage() ).
• Customizable easing, auto-pageflip duration, and size for the hit-regions (the page-corners whereby a page can be flipped).
• Distortion (instead of skewing) when flipping hardback pages.
• A variety of events that the book class dispatches, making customization alot simpler.
• Transparency support for pages.
• Live-bitmapping functionality for playing animation uninterrupted during pageflips.

Examples

• The Acanvas Dartbook Demo.
• The best way to learn how to use Acanvas Spring and Acanvas Framework by generating a project with Acanvas Generator.

Known Issues

• Partial animation glitch when flipping the pages backwards via tap/click
• Hard pages distorting at the bottom due to an issue with StageXL bitmapfill position data
• Scaling and touch behaviour suboptimal on some mobile devices

History

DartBook is a pretty direct port of FlexBook, and came to life like this:

1. Refactoring FlexBook from Flex to pure ActionScript
2. Writing Acanvas ActionScript Converter.
3. Making lots of tweaks to account for differences in the APIs
