<custom:SavableImage id="saveImage" name="” >

in above code filename will be image name coming from server. I have file name set in database column and actual file on server. So it was pretty easy to replace filename to {javadto.imagefilename}

Now in actionscript

===========================
var bmp:Bitmap = Bitmap(this.content);
var myEncoder:JPGEncoder = new JPGEncoder(75);
var byte:ByteArray = myEncoder.encode(bmp.bitmapData);
var fr:FileReference = new FileReference();
fr.save(byte, this.name);
=========================

save dialog will have same file name as source.

===========================
var bmp:Bitmap = Bitmap(this.content);
var myEncoder:JPGEncoder = new JPGEncoder(75);
var byte:ByteArray = myEncoder.encode(bmp.bitmapData);
var fr:FileReference = new FileReference();
fr.save(byte, “test.jpg”);
=========================

You have add this in saveImageAs function in source file SaveableImage.cs in Jamesward packge.

You need two additional file JPGEncodeer.as and BitString.as for conversion on client side. I can’t attach them on blog.

The contents of content.loaderInfo.bytes isn’t the image but rather the image embedded in a SWF. So I’m pulling the image out of the SWF by chopping off the first 49 bytes and then the last 17 bytes. I have no idea what’s in those bytes or if it’s always 49 and 17. So this needs some testing.

Alternatively there are a few other ways to do this:
– Re-fetch the image from the server
– Maybe find some place in memory where the non-SWF-ified image is and use those bytes
– Re-encode the image on the client

I opted to mess with the bytes instead of those options. But maybe someone smarter than me can find a cleaner way to do this.

Can you explain why you’re substracting 17 from image bytes length and set position to 49 in saveImageAs function?
