How can I convert a BufferedImage to an Image?
提问by dannYonkeys
I'm trying to split up an image of a deck of cards and store an individual card into an Image.
我正在尝试拆分一副纸牌的图像并将单张卡片存储到图像中。
Image image;
BufferedImage deck = ImageIO.read( new URL( "http://www.jfitz.com/cards/classic-playing-cards.png" ) );
image = deck.getSubimage( x, y, width, height );
incompatible types: BufferedImage cannot be converted to Image
不兼容的类型：BufferedImage 无法转换为 Image
Everywhere I've looked says that BufferedImage isan Image, this problem shouldn't exist. (Note: if this comes off looking like a class assignment, it is, but all we're supposed to do is load an image from a predetermined directory. I'm trying to take it a step further by using the URL for fun.)
我看过的所有地方都说 BufferedImage是一个图像，这个问题不应该存在。（注意：如果这看起来像一个类分配，它是，但我们应该做的就是从预定的目录加载图像。我试图通过使用 URL 来更有趣。 )
EDIT 04/09/2014
I've been using different imports, so I guess the question I'm really trying to ask is how to convert a java.awt.image.BufferedImage to a java.scene.image.Image. Thanks for the help so far!

我一直在使用不同的导入，所以我想我真正想问的问题是如何将 java.awt.image.BufferedImage 转换为 java.scene.image.Image。感谢你目前的帮助！

Once I knew what question to ask, google answered this really quickly. I found a quick fix on this blog.
一旦我知道要问什么问题，谷歌就很快回答了这个问题。我在这个博客上找到了一个快速修复。
BufferedImage tempCard = deck.getSubimage( x, y, width, height );
Image card = SwingFXUtils.toFXImage(tempCard, null );
Tried it out and works great!
试过了，效果很好！
回答by Chris Smith
Image image = new ImageIcon(bufferedImage).getImage();
That's the way I usually do it... OR
这就是我通常这样做的方式......或者
Image image = (Image) bufferedImage;

A BufferedImage extends Image which means that you can declare a BufferedImage like so:
A BufferedImage 扩展 Image 这意味着您可以像这样声明 BufferedImage ：
Image myImage = ImageIO.read(new URL("my/url"));
This starts getting into polymorphism and inheritance. Your object may be a BufferedImage, but a BufferedImage is still an Image and it can be used as one.
这开始进入多态和继承。您的对象可能是一个 BufferedImage，但 BufferedImage 仍然是一个 Image，它可以用作一个。
A more recognizable example perhaps would be instantiating an ArrayList as a List
一个更容易识别的例子可能是将一个 ArrayList 实例化为一个列表
List<MyType> aList = new ArrayList<>();
This allows this ArrayList to be compatible with all types of List objects, just like the BufferedImage.
这允许此 ArrayList 与所有类型的 List 对象兼容，就像 BufferedImage 一样。
Take a look at the API page for Image.
It lists all known subclasses of this abstract class, BufferedImage included. (There's only 2.)
它列出了这个抽象类的所有已知子类，包括 BufferedImage。（只有 2 个。）

BufferedImageis a subclass of Image. You don't need to do any conversion.
BufferedImage是Image的子类。您无需进行任何转换。
You can just assign like:
你可以像这样分配：
Image image;
BufferedImage deck = ImageIO.read( new URL( "http://www.jfitz.com/cards/classic-playing-cards.png" ) );
image = deck;// That will do
