How do I resize an imageview image in javafx?
提问by Jeremy
I need to resize an image to specific dimensions, 100 by 100 pixels for example, in JavaFX.
我需要在 JavaFX 中将图像调整为特定尺寸，例如 100 x 100 像素。
How can I achieve that? Could the Image or the ImageView class be used for this purpose?
我怎样才能做到这一点？Image 或 ImageView 类可以用于此目的吗？

Yes, using an ImageView. Just call
是的，使用ImageView. 打电话就行
ImageView imageView = new ImageView("...");
imageView.setFitHeight(100);
imageView.setFitWidth(100);
By default, it will not preserve the width:heightratio: you can make it do so with
默认情况下，它不会保留width:height比例：您可以使用
imageView.setPreserveRatio(true);
Alternately you can resize the Imagedirectly on loading:
或者，您可以在加载时直接调整图像大小：
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.
在加载时调整图像大小对于诸如较大图像的缩略图之类的事情很有用，因为所需的内存低于将较大的图像数据表示存储在内存中。
