带图像的JavaFX CSS按钮 - 如何定义图像的大小？

I am trying to insert an image in a button using JavaFX CSS. Although, I can do it easily using the "-fx-graphic" tag, I cannot find a way to resize the image in whatever size I want.

我试图使用JavaFX CSS在按钮中插入图像。虽然,我可以使用“-fx-graphic”标签轻松完成,但我无法找到一种方法来调整我想要的任何大小的图像。

I can do this through the following FXML code, where I give 30 to my preferred width of image, but I would like to do this with pure CSS. Is there any way to do that?

我可以通过以下FXML代码完成此操作,其中我给出了我喜欢的图像宽度30,但我想用纯CSS做到这一点。有没有办法做到这一点?

FXML

<Button text="Press Me">
   <graphic>
      <ImageView fitWidth="30">
        <image>
          <Image url="myImage.png"/>
        </image>
      </ImageView>
   </graphic>
</Button>

CSS

#buttonWithImage {          
    -fx-graphic: url("myImage.png");
}

I had the same problem and found a workaround: instead of using -fx-image, I use -fx-background-image.

我有同样的问题,并找到了一个解决方法:而不是使用-fx-image,我使用-fx-background-image。

Note: I use an additional lib to use svg file in the following example.

注意:在以下示例中,我使用其他lib来使用svg文件。

CSS

#buttonWithImage { 
    -fx-background-image: url('myimage.svg');
    -fx-background-size: 30px;
    -fx-background-repeat: no-repeat;
    -fx-background-position: 90%;
}
