列出您最喜欢的堆分析工具(例如jprofiler,jmap,...).让我们为每个答案保留一个工具,并列出每个工具的优缺点.

这是 JFrame

package client.connection;

import java.awt.Dimension;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import javax.swing.JFrame;


class DrawFrameRemoteControl extends JFrame
{
    private DrawPanelRemoteControl imagePanel;
    private ClientRemoteControlConnection clientRemoteControlConnection;
    private ObjectInputStream clientInputStream;
    private ObjectOutputStream clientOutputStream;
    private Dimension imageDimension;
    private Dimension serverDimension;

    public DrawFrameRemoteControl(Dimension imageDimension,ClientRemoteControlConnection clientRemoteControlConnection,ObjectInputStream clientInputStream,ObjectOutputStream clientOutputStream,Dimension serverDimension)
    {
        super("Remote Desktop Control");

        this.clientRemoteControlConnection=clientRemoteControlConnection;
        this.clientInputStream=clientInputStream;
        this.clientOutputStream=clientOutputStream;
        this.imageDimension=imageDimension;
        this.serverDimension=serverDimension;

        imagePanel=new DrawPanelRemoteControl(imageDimension);
        add(imagePanel);


        setSize(imageDimension.width,imageDimension.height);
        setResizable(false);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setVisible(true);
        setLocationRelativeTo(null);
    }

    void drawNewImageGrayscale(byte[] array)
    {
        imagePanel.setNewImageGrayscale(array);
        imagePanel.repaint();
    }
}

这是扩展的JPanel类 -

package client.connection;

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit; …

我正在Netbeans中创建一个Swing GUI.此GUI的目的是打开(缓冲)图像(在JLabel中作为图标)并在其上应用仿射变换.现在有4个转换,我正在做如下.

现在,每个变换需要两个滑块才能更改X和Y值,但旋转除外,只需要一个.我这样做是因为它比为所有4种类型的变换做四个选项卡要好得多.另外,我希望它是这样的,例如,如果旋转图像,可以通过从下拉列表中选择剪切来剪切相同的旋转图像.

问题是(是):如何重新绘制标签图标并对同一重新绘制的图像应用不同的变换？另外,如何在所选效果上更改JSlider depanding的最小值和最大值？
