在基本图像大小调整方面，您可以将QLabel类与QPixmap一起使用，一个简单的例子是这里 [ ^ ]。 QPixmap文档是此处 [ ^ ]。我相信有足够的信息可以用你的形象做你想做的事。

There is a huge amount of material on the Qt web site[^], including video training.

In terms of basic image resizing, you could probably use the QLabel class with QPixmap, a simple example is here[^]. And the QPixmap docs are here[^]. I''m sure there is plenty of information there to do what you want with your image.
