JavaFX - css adding background image with transparency

javacssjavafxbackground-image

提问by baxbear

I want to add an image (png) this way:

我想以这种方式添加图像(png):

#leftCorner {
  -fx-background-image: url("images/backgroundTrain2.png");
  -fx-background-repeat: stretch;
  -fx-background-size: 150.0 71.0;
  -fx-background-position: center center;
}

the problem is that I loose the transparency of the white part of the image. Can somebody tell me what I can do that it stays transparent?

问题是我失去了图像白色部分的透明度。有人能告诉我我能做些什么来保持透明吗?

I use -fx-background-color:transparentto set pngs on my Buttons and transparency works. Try this.

-fx-background-color:transparent过去常常在我的按钮和透明度上设置 png。尝试这个。
