我在普通J2EE应用程序中的工作示例:

// decode the image 
    InputStream inputStream = new File("/images/test.png");
    BufferedImage barCodeBufferedImage = ImageIO.read(inputStream);
    if (barCodeBufferedImage != null) {
        LuminanceSource source = new BufferedImageLuminanceSource(barCodeBufferedImage);
        BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
        Result results = new MultiFormatReader().decode(bitmap);
        //System.out.println("Decoded barcode image :: "+results.getText());
        return results.getText();
    }

同样我想在GAE中实现.但它阻止了ImageIO类和BufferedImage类.任何人都可以告诉我GAE上的ImageIO类的替代品吗？
