Qt QPixmap大小

Question

我想要一个QPixmap50 x 50的尺寸.我试过:

QPixmap watermark(QSize(50,50)); 
watermark.load(":/icoMenu/preparation");

但QPixmap采用图像大小.

我也尝试过:

QPixmap watermark(":/icoMenu/preparation");
watermark.scaled(QSize(50,50),  Qt::KeepAspectRatio);

但结果相同.

Answer 1

你几乎成功了

QPixmap watermark(":/icoMenu/preparation");

QPixmap newPixmap = watermark.scaled(QSize(50,50),  Qt::KeepAspectRatio);
