comparison layer/ColourScale.cpp @ 1362:d79e21855aef

Add mechanism for saving/loading colour maps by name/id rather than by numerical index, for future compatibility when adding to or changing the supported colour maps. Add two new colour maps (and one old one). Write out backward-compatible numerical indices for use when reloading in older versions. Also add a mechanism to invert the colour map, though I don't think it turns out useful enough to include in the UI.

 
 int ColourScale::m_maxPixel = 255;
 
 ColourScale::ColourScale(Parameters parameters) :
     m_params(parameters),
-    m_mapper(m_params.colourMap, 1.f, double(m_maxPixel))
+    m_mapper(m_params.colourMap, m_params.inverted, 1.f, double(m_maxPixel))
 {
     if (m_params.minValue >= m_params.maxValue) {
         SVCERR << "ERROR: ColourScale::ColourScale: minValue = "
              << m_params.minValue << ", maxValue = " << m_params.maxValue << endl;
         throw std::logic_error("maxValue must be greater than minValue");
