Updateted : How to write Jpeg || Png Files in Swf Files

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

Now you could use : 

 actionscript3 |  copy |? 
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.

How to save a SWF file at runtime with swfassist and FileReference

     
     

       
Here`s a little class to build a swf file at runtime with 2 images. Just an example :


Here you could find the swfassist framework. Unfortunately its not documented very well.

Just check out the svn for some examples.


JPGEncoder click here


I made a swf file with 20 frames, each frame the shown bitmap is switched. The swf could be saved locally on your Pc.
