Flex 视频 图象处理.docx

1、Flex 视频 图象 处理Flex采集摄像头照片-增加裁剪功能由于系统中用到的flex采集照片需要裁减功能，就把前几天搜到的Flex源码进行了修改，实现了裁减功能，不过做的比较简单，呵呵！Flex部分: Alertfont-size:12px; !CDATA import mx.events.CloseEvent; import mx.rpc.events.FaultEvent; import mx.rpc.events.ResultEvent; import mx.controls.Alert; private static const DEFAULT_CAMERA_WIDTH:Number
