The default values can be set using either by using LImageViewerCell::SetDefaultWindowLevelValues or can be internally calculated when the images are first set in the control using either LImageViewerCell::SetCellBitmapList or LImageViewerCell::SetRequestedImage (when the low memory usage feature is enabled). For more information about the low memory usage feature, refer to the function LImageViewerCell::EnableCellLowMemoryUsage.
To get the current window level values call LImageViewerCell::GetActionProperties.
To set the current window level values call LImageViewerCell::SetActionProperties.
To reset the window level values to the default values use the function LImageViewerCell::ResetWindowLevelValues.
