SAFEARRAY*到QByteArray

Question

我通过了c++调用(.)方法的结果类型为变量* var。var是.bmp图像。

qDebug() << var.vt; //8209 ~ VT_ARRAY|VT_UI1 ~ SAFEARRAY(BYTE)

如何将它从SAFEARRAY(字节)转换为QByteArray？或者如何获得QImage (QPixmap，QBitmap)？谢谢/.

伊戈尔，太感谢了！

long iLBound, iUBound;
char * data;
SafeArrayGetLBound(AFingerImage.parray, AFingerImage.parray->cDims, &iLBound);
SafeArrayGetUBound(AFingerImage.parray, AFingerImage.parray->cDims, &iUBound);
SafeArrayAccessData(AFingerImage.parray,(void**)(&data));
long sz = iUBound - iLBound + 1;
QByteArray ba = QByteArray::fromRawData(data,sz);
FPImage.loadFromData(ba);
SafeArrayUnaccessData(AFingerImage.parray);
