一、flex与word协作:??? 对于word,可将word文档模板文件存成xml格式,而此xml文档中的图片是以“base-64 encoded”,而flex3可以将生成的图片快照下来再转换成此格式,flex能够操作xml文件,从而可以修改word xml模板文件中的内容,从而与word协作。将ImageSnapshot对象利用flex3的encodeImageAsBase64()方法转换为base-64 encoded格式的例子:
?xml version=1.0 encoding=utf-8?!-- /2007/12/07/converting-an-imagesnapshot-object-into-a-base-64-encoded-string-in-flex-3/ --mx:Application xmlns:mx=/2006/mxml??????? layout=vertical??????? verticalAlign=middle??????? backgroundColor=white??? mx:Script??????? ![CDATA[??????????? import flash.events.FocusEvent;??????????? import flash.system.System;??????????? import mx.graphics.ImageSnapshot;??????????? private function button_click(evt:MouseEvent):void {??????????????? var ohSnap:ImageSnapshot = ImageSnapshot.captureImage(img);??????????????? textArea.text = ImageSnapshot.encodeImageAsBase64(ohSnap);??????????? }??????????? private function textArea_focusIn(evt:FocusEvent):void {??????????????? textArea.setSelection(0, textArea.text.length);??????????? }??????? ]]??? /mx:Script??? mx:ApplicationControlBar dock=true??????? mx:Button label=Capture and encode??????????????? click=button_click(event); /??? /mx:ApplicationControlBar??? mx:Form??????? mx:FormItem label=source:??????????? mx:Image id=img??????????????????? source=@Embed(images/flex_logo.jpg) /??????? /mx:FormItem??????? mx:FormItem label=Base64:??????????? mx:TextArea id=textArea??????????????????? editable=false??????????????????? showScrollTips=true??????????????????? width=320??????????????????? height=160??????????????????? focusIn=textArea_focusIn(event); /??????? /mx:FormItem??????? mx:FormItem??????????? mx:Button label=Copy to clipboard??????????????????? enabled={textArea.text.length 0}??????????????????? click=System.setClipboard(textArea.text); /??????? /mx:FormItem??? /mx:Form/mx:Application
