如何在vala中调整Gtk.Image的大小 [英] How to resize a Gtk.Image in vala

问题描述

我正在尝试调整vala中的图片大小.
所以我读了valadoc并最终编写了这段代码

I'm trying to resize a Image in vala.
So I read valadoc and end up writing this code

var img = new Gtk.Image.from_file ("fire.png");

var pix_buf = img.get_pixbuf ();
pix_buf.scale_simple (50, 50, InterpType.BILINEAR);

window.add (img);

但是没有效果.

如果有一种方法可以动态缩放图像以使其充满他的容器，那就太棒了，但是仅缩放它就可以了.

If there is a way to dynamically scale the image so that it fill his container it would be awesome, but just scaling it would be fine.

推荐答案

Image.from_pixbuf 创建新图像并添加到您的窗口.

Pixbuf.scale_simple does not modify the image. It returns a new Pixbuf that has been scaled. Use Image.from_pixbuf to create a new image and add that to your window.
