Flash developers/animators can now use APNGs to play their animations on iPhones and iPads natively in full true color with a high quality framerate. Just add your .SWF files as images in the WebApp and generate some APNGs with the SWF-to-APNG functionality! Being a multi-frame bitmap format, these animations will, of course, lose the ability to run any code and vector scalability. Some animations may experience some
warping since the animation is being rasterized to fixed frames.
Why convert from Flash to make APNGs? Flash has been an industry leading animation technology for decades with many years of existing content of amazing quality built. Leveraging the deep feature set will also allow developers to build new breathtaking animations. The APNG format allows animations to play on mobile devices such as iPhone, iPad and devices running other supported browsers such as Firefox.
Very old AS2-based files(Flash 8 and below) will need to be converted to a non-ancient version before they will work here. This is because the AS3 system needs to be able to manipulate their timelines. If this is the case, load your animations into Flash Professional and re-save them in the latest format.
If your animation is based on code rather than a pure timeline animation, it may produce unpredictable results.
