我正在制作一个java中的Multiframe DICOM播放器，这里是我使用过的代码：
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import org.dcm4che2.imageioimpl.plugins.dcm.DicomImageReaderSpi;
public class DicomMultiframePlayer extends JFrame implements ActionListener, Runnable {
private static final long serialVersionUID = 1L;
private JLabel fileLabel;
private JTextField fileField;
private JButton btnChoose;
private JButton btnPlay;
private JButton btnPause;
private JButton btnStop;
private JButton btnExit;
private Vector<BufferedImage> images;
private ImagePanel imagePanel;
private boolean stop;
private int currentFrame;
public DicomMultiframePlayer() {
super("DICOM Multiframe Player using dcm4che - by samucs-dev");
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.getContentPane().setLayout(new BorderLayout());
images = new Vector<BufferedImage>();
imagePanel = new ImagePanel();
fileLabel = new JLabel("File:");
fileField = new JTextField(30);
btnChoose = this.createJButton(25, 25, "...");
btnPlay = this.createJButton(80,25,"Play");
btnPause = this.createJButton(80,25,"Pause");

btnStop.setEnabled(false);
JPanel panelNorth = new JPanel();
panelNorth.add(fileLabel);

panelNorth.add(btnChoose);

panelSouth.add(btnPlay);
panelSouth.add(btnPause);

this.getContentPane().add(panelNorth, BorderLayout.NORTH);
this.getContentPane().add(imagePanel, BorderLayout.CENTER);
this.getContentPane().add(panelSouth, BorderLayout.SOUTH);
this.setSize(new Dimension(500,500));
this.setLocationRelativeTo(null);
this.setVisible(true);
}
@Override
public void run() {
while(true) {
if (!btnPlay.isEnabled()) {
if (stop) break;
currentFrame++;
if (currentFrame == images.size())
currentFrame = 0;
imagePanel.setImage(images.get(currentFrame));
try {
Thread.sleep(70);
} catch (InterruptedException e) {

}
}
}
}
@Override

if (e.getSource().equals(btnChoose)) {
JFileChooser chooser = new JFileChooser();
int action = chooser.showOpenDialog(this);
switch(action) {
case JFileChooser.APPROVE_OPTION:
this.openFile(chooser.getSelectedFile());
break;
case JFileChooser.CANCEL_OPTION:
return;
}
}
if (e.getSource().equals(btnPlay)) {
btnPlay.setEnabled(false);
btnPause.setEnabled(true);
btnStop.setEnabled(true);
stop = false;
new Thread(this).start();
}
if (e.getSource().equals(btnPause)) {
btnPlay.setEnabled(true);
btnPause.setEnabled(false);
btnStop.setEnabled(true);
stop = false;
}
if (e.getSource().equals(btnStop)) {
btnPlay.setEnabled(true);
btnPause.setEnabled(false);
btnStop.setEnabled(false);
stop = true;
currentFrame = 0;
imagePanel.setImage(images.get(0));
}
if (e.getSource().equals(btnExit)) {
System.exit(0);
}
}
private JButton createJButton(int width, int height, String text) {
JButton b = new JButton(text);
b.setMinimumSize(new Dimension(width, height));
b.setMaximumSize(new Dimension(width, height));
b.setPreferredSize(new Dimension(width, height));
b.addActionListener(this);
return b;
}
private void openFile(File file) {
images.clear();
try {
System.out.println("Reading DICOM image...");
ImageReader reader = new DicomImageReaderSpi().createReaderInstance();
FileImageInputStream input = new FileImageInputStream(file);
reader.setInput(input);
int numFrames = reader.getNumImages(true);
System.out.println("DICOM image has "+ numFrames +" frames...");
System.out.println("Extracting frames...");
for (int i=0; i < numFrames; i++) {
BufferedImage img = reader.read(i);
images.add(img);
System.out.println(" > Frame "+ (i+1));
}
System.out.println("Finished.");
} catch(Exception e) {
e.printStackTrace();
imagePanel.setImage(null);
return;
}
stop = false;
currentFrame = 0;
imagePanel.setImage(images.get(0));
}
private class ImagePanel extends JPanel {
private static final long serialVersionUID = 1L;
private BufferedImage image;
public ImagePanel() {
super();
this.setPreferredSize(new Dimension(1024,1024));
this.setBackground(Color.black);
}
public void setImage(BufferedImage image) {
this.image = image;
this.updateUI();
}
@Override
public void paint(Graphics g) {
if (this.image != null) {
g.drawImage(this.image, 0, 0, image.getWidth(), image.getHeight(), null);
}
}
};
public static void main(String[] args) {
new DicomMultiframePlayer();
}
}
这是我收到的错误：

关于我所缺少的内容或我应该如此不同的任何解决方案或帮助 谢谢
答案 0 :(得分：0)
您缺少JAI库。 dcm4che网站上有安装这些说明的说明。
不幸的是，JAI不再被维护。我相信dcm4che的人们已经从java.net派了源，并试图提供至少一些错误修复。
