Adobe Flash Player是一种广泛使用的、专有的多媒体程序播放器。它最初由Macromedia编写，在Macromedia被Adobe收购后由Adobe继续开发并分发。Adobe Flash Player 最初设计目的为播放2维向量动画，但至此之后成为适合开发创造丰富型互联网应用程序、流视频音频的工具。Flash Player使用向量图形的技术来最小化文件的大小以及创造节省网络带宽和下载时间的文件。因此Flash 成为嵌入网页中的小游戏、动画以及图形用户界面常用的格式。
New and Updated Features in Adobe Flash Player 13.0:
* Supplementary haracters enhancement support for TextField – This is a desktop enhancement for supporting surrogate pairs in the TextField control. Now, characters out of the Basic Multilingual Plane(BMP) with Unicode code points between U+10000 and U+10FFFF will work correctly in the TextField control. It greatly enlarges the code point range we support and includes characters like emotion symbols (emoticons) and complex CCJK characters. This feature has been under an extended beta period. We anticipate this being included into the release version of the Runtime 13 release.
* Full screen video message tweak – We’ve made a small tweak to the “Press Esc to exit full screen mode.” message that’s seen on full screen video. We’ve heard for sometime that this message obscures content and we wanted to make a change that both satisfies security concerns and customer viewing enjoyment. To help, we’ve simply moved the message towards the top of the screen from it’s original centered position.
* New Stage3D texture wrapping modes – Currently you can set the wrapping mode of a texture to either clamp or repeat. Using the repeat option will repeat the texture on both the U and V axis. However, in some use cases, you might only want to repeat the texture on only one axis, either u or v. This is now possible with two new parameters: REPEAT_U_CLAMP_V and CLAMP_U_REPEAT_V.
* Stage3D Anti-Aliasing for Render texture – Anti-Aliasing is a useful technology to improve image quality. We’ve now implemented hardware based Multisampling Anti-Aliasing (MSAA) on desktop platforms. To enable this please set the level from 0 to 4 in Context3D’s . setRenderToTexture()
