BufferedImage.getProperty介绍

[英]Returns a property of the image by name.
[中]按名称返回图像的属性。

代码示例

@Override
  public Object getProperty(String name, ImageObserver observer) {
    if ("url".equals(name)) { // NOI18N
      if (url != null) {
        return url;
      } else {
        return imageIcon.getImage().getProperty("url", observer);
      }
    }
    return super.getProperty(name, observer);
  }
}
