Flash產生實體圖檔的幾個方法

還是來整理一下這個問題
Flash端要如何產生一張實體的圖檔呢?
Flash8+AS2
Flash端使用BitmapData類別, 再用回圈把所有的相素值, 用POST的方法傳給伺服器端
然後伺服器端再依色碼重組。
缺點, 效能很差, 傳輸過程要用久。
Flash9+AS3
Flash端使用BitmapData類別, 繪置Flash畫面, 再使用adobe JPGEncoder將BitmapData編碼成
ByteArray格式, 使用POST,upload,或是remoting的方式, 將ByteArray格式傳給伺服器端
Flash10+AS3
Flash端使用BitmapData類別, 繪置Flash畫面, 再使用adobe JPGEncoder將BitmapData編碼成
ByteArray格式, 使用FileReference新增的功能, 直接下載一張圖檔。
分享一下奶小茶我製做的程式碼。

使用Flash9+AS3+upload的方式, 產生圖片檔。
伺服器端我用的是asp.net
程式碼爛掉了, 請下載SourceCode吧, Sorry
