JavaFX CSS Button with Image - How to define the size of the image?

问题

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.

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?

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.

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

CSS

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