绘制到图像的组件使用难看的字体渲染
当我将 Swing 组件渲染到图像时，字体与在屏幕上渲染组件时的字体不同。这是显示差异的图像：
这是代码：
public static BufferedImage renderComponent(Component component) {
int width = component.getWidth();
int height = component.getHeight();
BufferedImage buffImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
Graphics2D g = (Graphics2D) buffImage.getGraphics();
g.setFont(component.getFont());
g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
component.paint(g);
g.dispose();
return buffImage;
}
我应该更改什么才能完美Swing 组件的屏幕截图？ （该应用程序在 Windows 7 上运行）
When I'm rendering a Swing component to an image the fonts are different then when the component is rendered on screen. Here is an image showing the difference:
And this is the code:
public static BufferedImage renderComponent(Component component) {
int width = component.getWidth();
int height = component.getHeight();
BufferedImage buffImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
Graphics2D g = (Graphics2D) buffImage.getGraphics();
g.setFont(component.getFont());
g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
g.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
component.paint(g);
g.dispose();
return buffImage;
}
What should I change to make a perfect screen shot of a Swing component? (The app is running on Windows 7)

我猜你不应该提供渲染提示。
我为此使用 Screen Image 类（它基本上是您的代码还内置了一些其他功能）。
I would guess you should not be providing rendering hints.
I use the Screen Image class for this (it is basically your code with a few other features built in).
在比较ScreenImage类（由camickr建议）之后我找到了问题的原因。如果我创建一个类型设置为 TYPE_INT_RGB 而不是 TYPE_INT_ARGB 的 BufferedImage，字体就很好。
After comparing the ScreenImage class (suggested by camickr) I found the cause of the problem. If I create a BufferedImage with the type set to TYPE_INT_RGB instead of TYPE_INT_ARGB the fonts are fine.
