I need to resize an image to specific dimensions, 100 by 100 pixels for example, in JavaFX.
How can I achieve that? Could the Image or the ImageView class be used for this purpose?
Yes, using an ImageView
. Just call
ImageView imageView = new ImageView("...");
imageView.setFitHeight(100);
imageView.setFitWidth(100);
By default, it will not preserve the width:height
ratio: you can make it do so with
imageView.setPreserveRatio(true);
Alternately you can resize the Image directly on loading:
Image image = new Image("my/res/flower.png", 100, 100, false, false);
Resizing the image on loading is useful for things like thumbnails of larger images as the memory required is lower than storing the larger image data representation in memory.
