示例1: decode

@Override
public Result decode(BinaryBitmap image,
Map<DecodeHintType,?> hints) throws NotFoundException, FormatException {
try {
return doDecode(image, hints);
} catch (NotFoundException nfe) {
boolean tryHarder = hints != null && hints.containsKey(DecodeHintType.TRY_HARDER);
if (tryHarder && image.isRotateSupported()) {
BinaryBitmap rotatedImage = image.rotateCounterClockwise();
