title: Howe can I retrieve the correct image with correct alpha channel from QMimeData
body: <p>If we drag or copy an image with alpha channel to a application / clipboard it lose the alpha channel using Qt.
  Using:
  QImage clipImage = pMimeData->imageData().value();</p>
  
  <p>gives us 32 bit image with black background where it suppose to be transparent. The format of an image is always QImage::Format_RGB32. I tried to convert it to QImage::Format_ARGB32_Premultiplied and to extract the alpha channel but I received for alpha channel only black background which covers the whole portion of image. Howe can I retrieve the correct image with correct alpha channel from QMimeData.</p>
  
  <p>Cheers
