一直以來(lái)都是在百度寫的博客，今天不知道百度是哪抽風(fēng)。居然把我的博客給封了，上貼吧去發(fā)泄一番，結(jié)果帖子都給刪了。

不得不說(shuō)你百度厲害，你自己犯的錯(cuò)誤。讓我們這些用戶跟著受罪。我看今天很多博客都被封了，都不知道原因。提倡的用戶體驗(yàn)?zāi)?#xff1f;這也太差勁了吧。至少告訴我們哪里出現(xiàn)違反百度空間協(xié)議的文章或是文字了。太搞笑了。

算了，今天開(kāi)始在這里寫了，由于剛開(kāi)始學(xué)習(xí)AS3.0這里就記錄一些寫過(guò)的代碼和體會(huì)吧。

先發(fā)一個(gè)涂鴉板的代碼咯。

有撤銷和保存的功能。做撤銷的時(shí)候想了半天。最后用數(shù)組實(shí)現(xiàn)了。用了matrix類. bitmapdata.draw方法。
