如何在 javafx 中调整 imageview 图像的大小?
我需要在 JavaFX 中将图像调整为特定尺寸，例如 100 x 100 像素.
I need to resize an image to specific dimensions, 100 by 100 pixels for example, in JavaFX.
我怎样才能做到这一点?Image 或 ImageView 类可以用于此目的吗?
How can I achieve that? Could the Image or the ImageView class be used for this purpose?
推荐答案
是的，使用 ImageView.打个电话就行了
Yes, using an ImageView. Just call
ImageView imageView = new ImageView("...");
imageView.setFitHeight(100);
imageView.setFitWidth(100);
默认情况下，它不会保留 width:height 比率:您可以使用
By default, it will not preserve the width:height ratio: you can make it do so with
imageView.setPreserveRatio(true);
或者，您可以在加载时直接调整 图像 的大小:
Alternately you can resize the Image directly on loading:
Image image = new Image("my/res/flower.png", 100, 100, false, false);
在加载时调整图像大小对于较大图像的缩略图之类的事情很有用，因为所需的内存比将较大的图像数据表示存储在内存中要低.
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.
