Question

i have another piece for more advanced guys than me 😉

I am developing a simple flash application to create your own coat of arms. When finished creating, it would be nice to save it as an image to a client’s computer or to a database, i am not sure yet. The problem is making the image from swf content – i mean not the whole content, just a part of it, where the COA is. I have found some eamples on the web using some image encoders and PHP, but i cant’t understand how it works. Could anybody be so kind to explain me the basic principles of this? I want to make it as simple as possible.

Answer 1

First, draw the image (Sprite or MovieClip, etc) into a BitmapData:

var b: BitmapData = new BitmapData(640, 480, false, 0xffffffff); 
b.draw(mcToBeSaved);

Then, use e.g. as3corelib to encode the BitmapData into PNG or JPG files.

var ba: ByteArray = PNGEncoder.encode(b);

Then, for Flash 10, you can immediately get the user to save the image to a file, using FileReference’s save method.
