调整 Vaadin 图像的大小 [英] Resizing Vaadin Image

问题描述

我正在将文件中的图像插入 UI.我按照 这些 说明.

I am inserting an image from file into a UI. I am creating it in Vaadin 7.6.8 by following these instructions.

String basepath = VaadinService.getCurrent().getBaseDirectory().getAbsolutePath();
FileResource resource = new FileResource(new File(basepath + "/WEB-INF/images/image.png"));
Image image = new Image("", resource);

但是我根本无法重新缩放或调整图像大小.图像始终以全尺寸显示.

However I am unable to rescale or resize the image at all. The image is always being displayed in full size.

有没有一种方法可以不使用 CSS 缩小图像?

Is there a way that I can scale down the image without using CSS ?

推荐答案

您可以指定图像组件的高度和宽度，

You can specify height and width of the image component,

FileResource resource = new FileResource(new File("D:/image.jpg"));
Image image = new Image("", resource);
image.setWidth(200, Unit.PIXELS);
image.setHeight(200, Unit.PIXELS);
