Decoding ByteArray to BitmapData

This process is the opposite of the encode function. It allows you to decode encoded image data into bitmap data. It is the core functionality used to load a bitmap from file converting the file bytes to bitmap data.

var data:ByteArray = ...; // Encoded data from a file load for example

Image.service.addEventListener( ImageEvent.DECODE_COMPLETE, decodeAsync_completeHandler );
Image.service.addEventListener( ImageEvent.DECODE_ERROR, decodeAsync_errorHandler );

var success:Boolean = Image.service.decodeAsync( data );

When the decode operation completes you will receive either an ImageEvent.DECODE_COMPLETE event or an ImageEvent.DECODE_ERROR event:

function decodeAsync_completeHandler( event:ImageEvent ):void
{
    trace( "Decode successful" );
    
    // Use the bitmap data
    var b:Bitmap = new Bitmap( event.bitmapData );
    addChild( b );
}

function decodeAsync_errorHandler( event:ImageEvent ):void
{
    trace( "Decode failed: " + event.error );
}
