Flash functions realized with JavaScript/HTML5

Latest news

On this technology, a programmer named Simon Willison, in his blog, do a good analysis:

SmokeScreen entirely in the browser to run, read the SWF binary file, unzip (decompress and use a local JavaScript!), Extracted from the image with embedded audio, convert them to Base64 encoded data, then, will be one of the vector converted to SVG graphics animation. Open in Chrome Web Inspector, to conduct them in the presentation, you will see the real-time SVG. SmokeScreen even designs your own ActionScript interpreter like Hp Pavilion dm3 battery.

Smoak said he would soon open SmokeScreen based on open source protocol source code, at present, he has made several very nice demo, although still not perfect, but it has been able to see the Flash-based HTML5-style animation is Sony VGP BPS12 battery. The code does not support Flash video, however, HTML5 already have their own video programs. Smoak said that his mind is in a class of iPhone and iPad device, on the Flash animation style advertising, the technology most likely used in advertising the Hp pavilion dv2 battery and Acer UM09E31 battery.

After optimization, the technology can also be used for games, Willison said, infographics news site is a good use, also can be used to render cartoon style animation, such as presentation of Strongbad series.

But there are concerns, SmokeScreen can be well applied to those who speed and capacity are very limited power of laptop battery devices, and we look forward to after the open source code can be optimized. At present, only the latest browser that can use the technology, including Firefox 3.6, Chrome 5, Safari 4, and mobile Safari. Opera 10.5 Series is close to support, but not IE8, but Smoak said, IE9 promising.
