Java Stretch图标适合按钮

Question

我正在尝试调整我的图标大小,使其覆盖整个按钮并位于按钮的中心.当我尝试时,它会拉伸我的按钮并弄乱其他所有东西.我该怎么做？目前,我的代码是:

在我的类的构造函数中..

javax.swing.JButton Console = new javax.swing.JButton;
ScaleButtonImage(Console, ConsoleEnabledImage);

在那个班里..

private void ScaleButtonImage(javax.swing.JButton Button, java.awt.Image ButtonIcon) {
        double Width  = ButtonIcon.getWidth(Button);
        double Height = ButtonIcon.getHeight(Button);
        double xScale = 28/Width;//Button.getWidth() / Width;
        double yScale = 28/Height;//Button.getHeight() / Height;
        double Scale = Math.min(xScale, yScale);   //ToFit
        //double Scale = Math.max(xScale, yScale); //ToFill
        java.awt.Image scaled = ButtonIcon.getScaledInstance((int)(Scale * Width), (int)(Scale * Height), java.awt.Image.SCALE_SMOOTH);
        Button.setIcon(new javax.swing.ImageIcon(scaled));
    }

布局:

.addGroup(layout.createSequentialGroup()
                        .addComponent(Enable, javax.swing.GroupLayout.PREFERRED_SIZE, 28, javax.swing.GroupLayout.PREFERRED_SIZE)
                        .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
                        .addComponent(Graphics, javax.swing.GroupLayout.PREFERRED_SIZE, 28, javax.swing.GroupLayout.PREFERRED_SIZE)
                        .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
                        .addComponent(Debug, javax.swing.GroupLayout.PREFERRED_SIZE, 28, javax.swing.GroupLayout.PREFERRED_SIZE)
                        .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
                        .addComponent(Console, javax.swing.GroupLayout.PREFERRED_SIZE, 28, javax.swing.GroupLayout.PREFERRED_SIZE)
                        .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)

然后我将它们全部水平和垂直地连接起来,这样它们的大小都一样.

相反,它最终看起来像下面.此外,如果我更改第一个按钮的图标,由于我的约束,所有按钮都会改变大小.如何使图标适合按钮？

Answer 1

尝试这样的事情(如果我没有用括号做错):

JButton button = new JButton(new ImageIcon(((new ImageIcon(
            "path-to-image").getImage()
            .getScaledInstance(64, 64,
                    java.awt.Image.SCALE_SMOOTH)))));

这样你的图像将被调整大小(在我的例子中大小为64x64)并添加到button,如下例所示:

编辑:

这是调整图像大小和保持图像比例的方法:

ImageIcon ii = new ImageIcon("path-to-image");
int scale = 2; // 2 times smaller
int width = ii.getIconWidth();
int newWidth = width / scale;
yourComponent.setIcon(new ImageIcon(ii.getImage().getScaledInstance(newWidth, -1,
            java.awt.Image.SCALE_SMOOTH)));
