Javafx css按钮图形调整大小

Question

我想更改按钮内图标的大小。图像的大小为 512 x 512，我想调整为 16x16。那么，使用 javaFX CSS 实现这一目标的最佳方法是什么。

这是我到目前为止所做的：

#btnCancel.button {
    -fx-graphic: url("/img/close.png") ;
    -fx-graphic-size:16px 16px ; ( I think this property not exist in javafx css)

}

但这对我不起作用。

I am not aware of any css property that can be used directly to set the -fx-graphic's size but you can achieve similar results using -fx-background-image property. This will allow you to set width and height values using -fx-background-size.

You can access BackgroundSize's javadoc from this link

.logButton {
    /*
    -fx-graphic: url(images/log2.png);
    -fx-graphic-size:16px 16px;
    */
    -fx-background-image: url(images/log2.png);
    -fx-background-size: 64px 64px;
    -fx-background-repeat: no-repeat;
    -fx-background-position: center;
}
