Member Function Documentation

void ColorMap::Add (  float  elev, const RGBi &  color )

Add a color entry, keeping the elevation values sorted.

void ColorMap::GenerateColors (  std::vector< RGBi > &  table, int  iTableSize, float  fMin, float  fMax )  const

Generate an array of interpolated colors from this ColorMap. Parameters: table  An empty table ready to fill with the interpolated colors. iTableSize  The desired number of elements in the resulting table. fMin,fMax  The elevation range to interpolate over.
