SAFEARRAY* to QByteArray

I'm get through c++ invoke(...) method result at type VARIANT * var. var is .bmp image.

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

How convert it from SAFEARRAY(BYTE) to QByteArray? Or how get QImage (QPixmap, QBitmap)? Thanks/.

Solution

  • Igor, great thanks!!!

    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);
