           Summary: Preview not working in image effect dialogs
           Product: digikam
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: gandalf.lechner esi ac at


Version:           0.10.0-beta2 (rev.: 830788) (using 4.00.83 (KDE 4.0.83 (KDE 4.1 Beta2), Kubuntu packages)
Compiler:          gcc
OS:                Linux (x86_64) release 2.6.24-19-generic

When applying some effect to a picture, the preview for the result does not work correctly.

This applies apparantly to all effects using a split original/target preview, e.g. the effects collected in the Color menu. When launching an effect dialog, the "original" half of the preview is there and looks correct, but the "target" part is just missing. Clicking on some of the split options (horizontal, vertical etc) results in showing the "target" half of the preview, but without the effect being applied.

Selecting OK however results in the correct application of the selected effect, just the preview is not working as expected.

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();
