貌似有点问题,只派发一次事件啊
使用ActionScript 2.0或ActionScript 3.0处理音频文件的提示点(cue
和师傅写C#写的思维混乱,方法变量几乎第一反应就是大写,习惯都被改写了,.NET在代码管理上的确比Flex强悍的多。
OK,进入主题,毕设还没结束就先回公司报道了,哈哈,接下来事情不少。这个是一个项目开始要用到的,一大堆的Rectangle运算处理,头痛了一整天,其中的SelectRectanle用于选取框的生成,可拖拽,缩放,返回一个给定可视元素的被选区域(Rectangle), CutImage用于剪裁图片。
查看源代码:http://www.moorwind.com/as3app/imageprocess/srcview/index.html
代码中注意,因为要对图片进行操作,所以使用了URLStream()加载待处理图像。
