swt byte[] 与 Image的转换

1. 从byte[]得到Image 

private static Image createImage(byte[] imageBytes) {
    Image image = null;
    try {
        ByteArrayInputStream bais = new ByteArrayInputStream(imageBytes);
        image = new Image(null, bais);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return image;
}

2. 从Image得到byte[] 

public static byte[] getImageBytes(Image image) throws Exception {
ByteArrayOutputStream baos = new ByteArrayOutputStream();

ImageLoader imageLoader = new ImageLoader();
imageLoader.data = new ImageData[] { image.getImageData() };
imageLoader.save(baos, image.type);

byte[] imageByteArray = baos.toByteArray();
try {
baos.close();
} catch (Exception e) {
e.printStackTrace();
}

return imageByteArray;
}
