通過套接字發送BufferedImages

Question

我想通過自定義類在網絡上發送緩沖的圖像。

我目前只是writeObject和readObject來獲取我的課程。

發送當前正在執行的圖像：

((DataBufferByte) i.getData().getDataBuffer()).getData();

如何將其轉換回BufferedImage？

有沒有更好的方法可以做到這一點？

我發送的課程如下：

public class imagePack{

public byte[] imageBytes;
public String clientName;
public imagePack(String name, BufferedImage i){
    imageBytes = ((DataBufferByte) i.getData().getDataBuffer()).getData();
    clientName = name;
}

    public BufferedImage getImage(){
     //Do something to return it}

}

再次感謝

如果要將其轉換回BufferedImage，還必須知道其寬度，高度和類型。

class imagePack {

    public byte[] imageBytes;
    public int width, height, imageType;
    public String clientName;

    public imagePack(String name, BufferedImage i) {
        imageBytes = ((DataBufferByte) i.getData().getDataBuffer())
                .getData();
        width = i.getWidth();
        height = i.getHeight();
        imageType = i.getType();
        clientName = name;
    }

    public BufferedImage getImage() {
        if (imageType == BufferedImage.TYPE_CUSTOM)
            throw new RuntimeException("Failed to convert.");
        BufferedImage i2 = new BufferedImage(width, height, imageType);
        byte[] newImageBytes = ((DataBufferByte) i2.getData()
                .getDataBuffer()).getData();
        System.arraycopy(imageBytes, 0, newImageBytes, 0, imageBytes.length);
        return i2;
    }
}
