I need set some action like this

            memset (&WLAttr, 0, sizeof(DISPWLEVELACTIONPROPS));
            WLAttr.DispContainerActionProps.uStructSize = sizeof(DISPWLEVELACTIONPROPS);
            m_LImageViewer.GetActionProperties(CONTAINER_ACTION_WINDOWLEVEL, 0, 0, &WLAttr, CONTAINER_ACTION_CELLLEVEL);
            WLAttr.nWidth = pImage->nWidth;
            WLAttr.nCenter = pImage->nCenter;
            m_LImageViewer.SetActionProperties(CONTAINER_ACTION_WINDOWLEVEL, 0, 0, &WLAttr, CONTAINER_ACTION_CELLLEVEL);

            // Reset Cell properties
            memset (&ScaleAttr, 0, sizeof(DISPSCALEACTIONPROPS));
            ScaleAttr.DispContainerActionProps.uStructSize = sizeof(DISPSCALEACTIONPROPS);
            m_LImageViewer.GetActionProperties(CONTAINER_ACTION_SCALE, 0, 0, &ScaleAttr, CONTAINER_ACTION_CELLLEVEL);
            ScaleAttr.uScale = m_nViewScale[m_nCamDevice];
            int nHW  = max(m_ImgSizeX, m_ImgSizeY);
            ScaleAttr.uScale = min(m_DstRect.Width(), m_DstRect.Height()) * 100 / nHW;
            m_LImageViewer.SetActionProperties(CONTAINER_ACTION_SCALE, 0, 0, &ScaleAttr, CONTAINER_ACTION_CELLLEVEL);

            // Modify offset
            memset (&Props, 0, sizeof(DISPOFFSETACTIONPROPS));
            Props.DispContainerActionProps.uStructSize = sizeof(DISPOFFSETACTIONPROPS);
            m_LImageViewer.GetActionProperties (CONTAINER_ACTION_OFFSET, 0, 0, &Props, CONTAINER_ACTION_CELLLEVEL);
            Props.nXOffset = 0;
            Props.nYOffset = 0;
            m_LImageViewer.SetActionProperties (CONTAINER_ACTION_OFFSET, 0, 0, &Props, CONTAINER_ACTION_CELLLEVEL);

as I know ver 16, 17 have BeginUpdate and EndUpdate, but 15 is not.
How can I stimulate this function in ver 15.

thank you.

Do you want this to reduce flickering while updating the actions?
If yes, I'm afraid that we didn't have a similar feature in v15. This was only added in later versions. If you would like to consider upgrading, please visit our website and download the free evaluation edition of LEADTOOLS 17 to test all the features you need before making a decision.
