java - 如何使图像相对于其框架缩放(ImageJ)

Question

所以我想我问了一个新问题，这是我的旧问题的延伸。因此，我能够将 ImageJ 窗口中的内容放入桌面 Pane 内的 JInternal 框架中。但图像不会随着帧尺寸的放大而缩放。我发现了几种主要使用 ImageJ 中的缩放类的方法，但它不会缩放以适应框架。所以我想知道是否有人知道我做错了什么。放大可以工作，缩小也可以，但是缩放和缩放的设置不起作用，我不知道为什么。预先感谢。

这是我的代码的一部分:

public class CustomGui extends ImageWindow implements InternalFrameListener, ComponentListener, ActionListener{

    public CustomGui(ImagePlus imp, String title, JDesktopPane desktop, final JMenuItem save, JWindow win, JMenuItem fft) {
        super(imp);
        // TODO Auto-generated constructor stub
        setCall();
        img = imp;
        save.setEnabled(true);
        fft.setEnabled(true);
        //this.title = title;
        this.win = win;
        this.fft = fft;
        this.save = save;


        JPanel panel = new JPanel();

        ImageCanvas c = new ImageCanvas(imp);
        c.getImage();

        //panel2.add(new JLabel(new ImageIcon(c.getImage())));
         m = new ImageWindow(img);

        Image n = new Image();
        frame = new MyInternalFrame(title, img, save,m);
        //ImageCanvas c = m.getCanvas();
        ImagePlus im = new ImagePlus();
        im.setImage(img);


        //ImageRoi roi = ImageRoi();
        //panel.add(c);
       //   frame.add(m.getContentPane());
        m.centerNextImage();

      //This is where I try to use the zoom class.
        img.getCanvas().setScaleToFit(true);

        //ImageCanvas nu = new ImageCanvas(img);
        //nu.setScaleToFit(true);

     //I set arg to "scale" but it doesn't work, even when I put it in component resized listener.
        Zoom z = new Zoom(img);
        String arg = "orig";
        z.run(arg);

        //m.setLocationRelativeTo(frame);
        //m.setLocationAndSize(true);
        //m.setLocationAndSize(frame.getWidth(), frame.getHeight(), frame.getWidth(), frame.getHeight());
        panel.add(m.getCanvas());
        panel.setBackground(Color.white);

        frame.add(panel);
        frame.setVisible(true); 
        frame.setAutoscrolls(true);
        frame.setAutoscrolls(true);
        desktop.add(frame);
        try {
                frame.setSelected(true);
        } catch (java.beans.PropertyVetoException e) {

        }
       frame.addInternalFrameListener(this);  
       frame.addComponentListener(this);
       //win.add(desktop);

    }

    public void actionPerformed(ActionEvent e){
        if(e.getActionCommand().equals(SHOW)){
            save.setEnabled(true);
            frame.addInternalFrameListener(this);
        }

        System.out.println("beingg called");
    }

      public void setCall(){
            called = true;
        }

        public void setCallF(){
        called = false;
        }

        public boolean getCall(){
        return called;
        }



      //This is where the internal frame is resized.
    @Override
    public void componentResized(ComponentEvent arg0) {
        // TODO Auto-generated method stub
        Rectangle r = frame.getBounds();
    //      int h = (int) r.getHeight();
    //      int w = (int) r.getWidth();
    //      m.resize(w, h);
        //m.getCanvas().unzoom();
        //m.setLocationAndSize((int)r.getWidth(), (int)r.getHeight(), (int)r.getWidth(), (int)r.getHeight());
        m.getCanvas().fitToWindow(r);
        System.out.println("resized- the real one");

    }

    @Override
    public void componentShown(ComponentEvent arg0) {
        // TODO Auto-generated method stub
        frame.show();

    }

    }

我还向 Zoom 类添加了一个构造函数(这是 Zoom 类的一部分):

    /** This plugin implements the commands in the Image/Zoom submenu. */
   public class Zoom implements PlugIn{

ImagePlus imp;
public Zoom (ImagePlus img){
    imp = img;
}

public void run(String arg) {
    //ImagePlus imp = WindowManager.getCurrentImage();
    //ImagePlus imp = img;
    if (imp==null)
        {IJ.noImage(); return;}
    ImageCanvas ic = imp.getCanvas();
    if (ic==null) return;
    Point loc = ic.getCursorLoc();
    if (!ic.cursorOverImage()) {
        Rectangle srcRect = ic.getSrcRect();
        loc.x = srcRect.x + srcRect.width/2;
        loc.y = srcRect.y + srcRect.height/2;
    }
    int x = ic.screenX(loc.x);
    int y = ic.screenY(loc.y);
    if (arg.equals("in")) {
        ic.zoomIn(x, y);
        if (ic.getMagnification()<=1.0) imp.repaintWindow();
    } else if (arg.equals("out")) {
        ic.zoomOut(x, y);
        if (ic.getMagnification()<1.0) imp.repaintWindow();
    } else if (arg.equals("orig"))
        ic.unzoom();
    else if (arg.equals("100%"))
        ic.zoom100Percent();
    else if (arg.equals("to"))
        zoomToSelection(imp, ic);
    else if (arg.equals("set"))
        setZoom(imp, ic);
    else if (arg.equals("max")) {
        ImageWindow win = imp.getWindow();
        win.setBounds(win.getMaximumBounds());
        win.maximize();
    } if (arg.equals("scale"))
        scaleToFit(imp);
}

Answer 1

在 Zoom.java ，我没有看到任何构造函数接受参数。您确定要导入并使用 ij.plugin.Zoom ？

标准 ImageJ GUI 允许使用 ij.plugin.Zoom 类进行缩放。在 Fiji's script editor 中运行以下 JavaScript 片段在正常和缩放以适应模式之间切换:

zm = new Zoom();
zm.run("scale");

ImageJ 主窗口的状态栏(以及 Zoom.java 的源代码)还提供了提示，在调整窗口大小时按 alt 将显示图像缩放到窗口大小。

抱歉，我没有花时间摆弄您的代码:它并不是真正的 minimal example .
