What works is this type of preview:
    Digikam::DImg imDest = m_threadedFilter->getTargetImage();
    m_imagePreviewWidget->setPreviewImage(imDest);

The tape that doesn't work is this:
    Digikam::DImg preview(w, h, sb, a, m_destinationPreviewData);
    Digikam::HSLModifier cmod;
    cmod.setHue(hu);
    cmod.setSaturation(sa);
    cmod.setLightness(lu);
    cmod.applyHSL(preview);
    iface->putPreviewImage(preview.bits());
    m_previewWidget->updatePreview();
