示例1: ImagePropertiesSample
import javafx.scene.image.ImageView; //导入方法依赖的package包/类
public ImagePropertiesSample() {
//we can set image properties directly during creation
ImageView sample1 = new ImageView(new Image(url, 30, 70, false, true));
ImageView sample2 = new ImageView(new Image(url));
//image can be resized to preferred width
sample2.setFitWidth(200);
sample2.setPreserveRatio(true);
ImageView sample3 = new ImageView(new Image(url));
//image can be resized to preferred height
sample3.setFitHeight(20);
sample3.setPreserveRatio(true);
ImageView sample4 = new ImageView(new Image(url));
//one can resize image without preserving ratio between height and width
sample4.setFitWidth(40);
sample4.setFitHeight(80);
sample4.setPreserveRatio(false);
sample4.setSmooth(true); //the usage of the better filter
ImageView sample5 = new ImageView(new Image(url));
sample5.setFitHeight(60);
sample5.setPreserveRatio(true);
//viewport is used for displaying the part of image
Rectangle2D rectangle2D = new Rectangle2D(50, 200, 120, 60);
sample5.setViewport(rectangle2D);
//add the imageviews to layout
HBox hBox = new HBox();
hBox.setSpacing(10);
hBox.getChildren().addAll(sample1, sample3, sample4, sample5);
//show the layout
VBox vb = new VBox(10);
vb.getChildren().addAll(hBox, sample2);
getChildren().add(vb);
}
示例2: createIconContent
import javafx.scene.image.ImageView; //导入方法依赖的package包/类
public static Node createIconContent() {
//TODO better icon?
ImageView iv = new ImageView(BRIDGE);
iv.setFitWidth(80);
iv.setFitHeight(80);
iv.setViewport(new Rectangle2D(0, 85, 330, 330));
return iv;
}
示例3: createIconContent
import javafx.scene.image.ImageView; //导入方法依赖的package包/类
public static Node createIconContent() {
ImageView iv = new ImageView(BOAT);
iv.setFitWidth(80);

ImageView imageView = new ImageView((Image) item);
double width = ((Image) item).getWidth();
double height = ((Image) item).getHeight();
double x = 0;
double y = height / 4;
// define crop in image coordinates:
Rectangle2D croppedPortion = new Rectangle2D(x, y, width, height / 3);
imageView.setViewport(croppedPortion);
imageView.setFitWidth(180);
imageView.setFitHeight(50);
imageView.setSmooth(true);
setGraphic(imageView);
