使用javafx显示具有透明背景的PNG文件 [英] Showing a PNG file with transparent background using javafx

问题描述

我实际上是在不使用javaFX的情况下在启动屏幕上工作的，everythink可以正常工作，但是我想在启动屏幕上显示带有透明背景的png图像，但无法执行此操作，有人可以告诉我是否可以这样做是否从JavaFX Scene Builder中获取它?

Am actually working on a splash Screen unsing javaFX, everythink works fine but I want to show a png image with a transparent background on the splash screen, but am unable to do it, can someone please tell me if it's possible to do it from JavaFX Scene Builder or not ?

推荐答案

我有点着急，但是下面是一个简单的示例，向您展示如何通过将StageStyle设置为Transparent和场景来完成此操作.填充为透明"颜色.

I'm in a bit of a rush, but below is a quick example to show you how it can be done by setting the StageStyle to Transparent and the scene fill to the color "transparent".

@Override
public void start(Stage aStage) throws Exception {
    Pane root = new Pane();
    ImageView img = new ImageView();
    img.setImage(new Image(getClass().getResource("pathToYourPngLocatedInYourResourcesFolder.png").toExternalForm()));
    root.getChildren().add(img);
    Scene scene = new Scene(root, 500, 500);
    scene.setFill(Color.TRANSPARENT);
    aStage.initStyle(StageStyle.TRANSPARENT);
    aStage.setScene(scene);
    aStage.show();
}

让我知道它是如何工作的:)

Let me know how it works out :)
