}

推荐答案

致电 getScaledInstance（） 在创建 ImageIcon 之前将图像缩放到所需的大小。您无需在标签上调用 setMinimumSize 。

Call getScaledInstance() to scale the image to the size you want before you create the ImageIcon. You don't need to call setMinimumSize on the label.

Image image = toolkit.getImage("pic.jpg");
Image scaledImage = image.getScaledInstance(50, 70, Image.SCALE_DEFAULT);   
ImageIcon icon=new ImageIcon(scaledImage);
