Question

有没有办法只将模糊效果添加到由窗格区域定义的图像的一部分？如果您在图像上模糊窗格，只有窗格变得模糊，但有没有办法模糊下面的图片部分？

这是我的意思的一个例子：它只是一个覆盖有窗格的图像，该窗格具有背景和不透明度设置。现在我想模糊窗格所在的部分。

Main.java：

package application;

import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.GridPane;
import javafx.fxml.FXMLLoader;

public class Main extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {
            GridPane root = (GridPane)FXMLLoader.load(getClass().getResource("Sample.fxml"));
            Scene scene = new Scene(root,500,500);
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        launch(args);
    }
}

Sample.fxml：

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.image.Image?>
<?import javafx.scene.image.ImageView?>
<?import javafx.scene.layout.ColumnConstraints?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.layout.Pane?>
<?import javafx.scene.layout.RowConstraints?>

<GridPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.111">
  <columnConstraints>
      <ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
    <ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
    <ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
  </columnConstraints>
  <rowConstraints>
    <RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
    <RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
    <RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
  </rowConstraints>
   <children>
      <ImageView fitHeight="495.0" fitWidth="535.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="1" GridPane.halignment="CENTER" GridPane.rowIndex="1" GridPane.valignment="CENTER">
         <image>
            <Image url="@../../../../Downloads/ZGEX2eX.jpg" />
         </image>
      </ImageView>
      <Pane prefHeight="200.0" prefWidth="200.0" style="-fx-background-color: #012E56; -fx-opacity: 0.666;" GridPane.columnIndex="1" GridPane.halignment="CENTER" GridPane.rowIndex="1" GridPane.valignment="CENTER" />
   </children>
</GridPane>

您可以使用Clip的{{1}}仅将效果应用于图片的特定区域：

ImageView

JavaFX在窗格区域下方模糊
