QRcode是啥呢?
1.新增視訊
2.將視訊圖檔用BitmapData存下來
3.設定存檔擷取圖像
4.給外部AS比對圖檔(使用zxing,快去下載來用!)
5.自己製作屬於自己的QRcode
6.GO!
步驟一:(程式碼)
步驟一:(程式碼)
var camera:Camera = Camera.getCamera(); var videoDisplay:Video = new Video(300,300); camera.setMode(300, 300, 24); camera.setQuality(0, 100); videoDisplay.attachCamera(camera); addChild(videoDisplay);步驟二:
bmd = new BitmapData(300,300); bmd.draw(videoDisplay, null, null, null, null, true);步驟三:
function decodeSnapshot():void
{
videoDisplay.cacheAsBitmap = true;
decodeBitmapData(bmd, 300, 300);
bmd.dispose();
bmd = null;
}
步驟四:
function decodeBitmapData(bmpd:BitmapData, width:int, height:int):void
{
var lsource:BufferedImageLuminanceSource = new BufferedImageLuminanceSource(bmpd);
var bitmap:BinaryBitmap = new BinaryBitmap(new GlobalHistogramBinarizer(lsource));
var ht:HashTable = getAllHints();
var res:Result = null;
try
{
res = _myReader.decode(bitmap,ht);
}
catch (event:Error)
{
}
if (res == null)
{
videoDisplay.clear();
}
else
{
var parsedResult:ParsedResult = ResultParser.parseResult(res);
var QRcodeResult:String = parsedResult.getDisplayResult();
}
}
function getAllHints()
{
var ht:HashTable = new HashTable ;
ht.Add(DecodeHintType.POSSIBLE_FORMATS, BarcodeFormat.QR_CODE);
return ht;
}
