来自HBITMAP的QImage [英] QImage from HBITMAP

问题描述

在仅Windows程序中，我使用第三方库，该库返回HBITMAP.

In my windows-only program, I use a third-party library, which returns a HBITMAP.

是否可以从其内容初始化QImage，即将其转换为QImage?

Is there a way to initialize a QImage from its contents, i.e. to convert it to a QImage?

推荐答案

这是Qt 4(QtGui)的解决方法:

This is the way to do it for Qt 4 (QtGui):

QImage image(QPixmap::fromWinHBITMAP(hBitmap).toImage());

这是Qt 5(QtWinExtras)的一种实现方法:

This is the way to do it for Qt 5 (QtWinExtras):

QPixmap pixmap = QtWin::fromHBITMAP(hBitmap);
QImage image = pixmap.toImage();

// or

QtWin::imageFromHBITMAP(hdc, hBitmap, width, height)
