Saving BitmapData as jpeg file

Question

I've been working on an AIR image editing application for a
few weeks now and i'm suddenly realizing that there seems to be no
easy way to save BitmapData as a JPEG file. I have found flash
examples that call php scripts in order to save jpegs, but is this
even possible when running only local code? How can I do this???
Will this functionality be available any time soon? Any suggests of
ways to do this would be GREATLY appreciated.
Thanks!

Answer 1

Well I have only used the JPGEncoder class, but the
PNGEncoder seems to work the same way... All I needed was something
to take my BitmapData object and give me a ByteArray that can be
written to meet the jpeg format specification. So basically, you'd
do something like this:
//assuming you already have some BitmapData called
myBitmapData
var stream:FileStream = new FileStream();
stream.open(newFile, FileMode.WRITE);
var bytes:ByteArray = new PNGEncoder().encode(myBitmapData);
stream.writeBytes(bytes);
stream.close();
If you need to do something a little different, you might
need to look through the functions in the PNGEncoder class a little
more.
Also, if you were implying you're actually confused as to how
to import the corelib, you should be able to either import it as a
new project or import the com.adobe.images package into your
current project and use the classes that way.
Hopefully this helps... I'm still sorta just getting the hang
of this stuff myself.
