SliceViewerWindow
=================

    The SliceViewerWindow is a window containing a SliceViewer widget
    and a LineViewer Widget.

    It allows you to look at 2D slices in a workspace such as a
    MDEventWorkspace or a MDHistoWorkspace, and then perform 1D line
    sections.

    You can access the two contained widgets using:
        getSlicer() (for the SliceViewer)
        getLiner() (for the LineViewer)

    However, the methods of the SliceViewer are exposed to the
    SliceViewerWindow, so you do not need to get the SliceViewer
    widget directly; you can call the methods on the SliceViewerWindow
    directly. For example:

       svw.setSlicePoint(2, 10.5)

    See the methods for SliceViewer, below.

        max :: maximum value corresponding to the lowest color on the map
    
    Raises:
        std::invalid_argument if max < min or if the values are
           inconsistent with a log color scale

    Set whether the color scale is logarithmic
   
    Args:
        log :: true for a log color scale, false for linear
    
    Raises:
        std::invalid_argument if the min/max values are inconsistent
           with a log color scale

%Docstring
void SliceViewer::setColorScaleAutoFull()
-----------------------------------------
    Automatically sets the min/max of the color scale,

    (every bin, even those not currently visible).
   
%End

  void setColorScaleAutoSlice() ;
%Docstring
void SliceViewer::setColorScaleAutoSlice()
------------------------------------------
    Automatically sets the min/max of the color scale,

    in the plot (only the bins in this slice and within the
    view limits)

  void setColorMapBackground(int r, int g, int b);
%Docstring
void SliceViewer::setColorMapBackground(int r, int g, int b)
------------------------------------------------------------
    Set the "background" color to use in the color map. Default is white.
   
    This is the color that is shown when:
   
     - The coordinate is out of bounds of the workspace.
     - When a signal is NAN (not-a-number).
     - When the signal is Zero, if that option is selected using setTransparentZeros()
   
    Args:
        r :: red component, from 0-255
        g :: green component, from 0-255
        b :: blue component, from 0-255
   
%End

  void setTransparentZeros(bool transparent);
%Docstring
void SliceViewer::setTransparentZeros(bool transparent)
-------------------------------------------------------
    Set whether to display 0 signal as "transparent" color.
   
    Args:
        transparent :: true if you want zeros to be transparent.
