我做了一个java rmi based application，我传递并从服务器接收一个ImageIcon对象...

(图像存储在服务器中的单独URL中)

该功能涉及以下内容....

1. Getting the image from the server at first....(on button press A)

2. Replacing it with a image file in the client[optional]....(on button press B)

3. Remove the image with a default image[optional]....(on button press C)

4. Sending it back to the Server....................(On button press D).....此处图像显示在一个名为img_label的jlabel中

我使用的代码如下.....

使用的变量

java.awt.Image img;

javax.swing.ImageIcon CurrentImageIcon;

javax.swing.ImageIcon DefaultImageIcon;

// CurrentImageIcon contains the image to be displayed in the img_label....

// img is used for copying as well for scaling......

// DefaultImageIcon holds the default Image......在按钮上按A键

img = temp.getImage();

CurrentImageIcon = new ImageIcon(img);

// Assuming temp holds the ImageIcon taken from the server.......

img=img.getScaledInstance(83,85 , Image.SCALE_DEFAULT);

img_label.setIcon(new ImageIcon(img));

img_label.revalidate();

img_label.repaint();按下按钮B

String url_text = jTextField.getText(); // taking the url frm the field.....

CurrentImageIcon = new ImageIcon(url_text);

img=CurrentImageIcon.getImage();

img=img.getScaledInstance(83,85 , Image.SCALE_DEFAULT);

img_label.setIcon(new ImageIcon(img));

img_label.revalidate();

img_label.repaint();按下按钮C

img = DefaultImageIcon.getImage();

CurrentImageIcon = new ImageIcon(img);

img=img.getScaledInstance(83,85 , Image.SCALE_DEFAULT);

img_label.setIcon(new ImageIcon(img));

img_label.revalidate();

img_label.repaint();在按钮上按D键

// ImagetoSend is an ImageIcon to be sent to the Server.....

ImagetoSend = CurrentImageIcon;

CurrentImageIcon = null;现在我得到的问题是一个奇怪的......

图像越来越嵌入，因为我想重新绘制时，我点击这个按钮........

But when i download the recently uploaded image next time on Button press A....it is displayed either magnified or reduced to size even though i included the getScaledInstance method....

喜欢这个...

我正在处理的图像是一个jpg图像....

我甚至在服务器目录中检查了镜像.....从客户端上传到服务器的文件没有发生大小变化。但是当它被下载并嵌入到jlabel中时，就会观察到这种变化...

任何人都可以帮我解决这个问题......？
