In my windows-only program, I use a third-party library, which returns a HBITMAP
.
Is there a way to initialize a QImage
from its contents, ie to convert it to a QImage
?
This is the way to do it for Qt 4 (QtGui):
QImage image(QPixmap::fromWinHBITMAP(hBitmap).toImage());
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)
好的,这似乎对我有用:
QImage image(QPixmap::fromWinHBITMAP(hBitmap).toImage());
Qt5 without Extras: Put before your code
#include <QPixmap>
Q_GUI_EXPORT QPixmap qt_pixmapFromWinHBITMAP(HBITMAP bitmap, int hbitmapFormat=0);
and in your function, for example
QPixmap pixmap = qt_pixmapFromWinHBITMAP(LoadBitmap(uiID));
Cheers
