privatefunction

Today I wrote a new Class using swf assist for writing Jpeg or PNG files to a SWF File.

Now you could use :

1
_imagePro = new ImageToSwfProcessor();
2
_imagePro.addEventListener(ImageProcessorEvent.NEXT_FILE, handleNextFile, false, 0, true);
3
_imagePro.writeSwfFromImage(image:*,quality : int ,"png" || "jpeg" : String, framecount : int);

Method wirteSwfFromImage has some Parameters.

1) The decent File as swf, jpeg or what else.

2) quality is used if image is jpeg or swf.

3) type is used to determ the current file. Only png or jpeg are used

4) framecount used to increment frames.

The Listener is called if you have many Files to store in a swf file. After each swf writing Process that listener would dispatch.

Here is that one.
