class TEveRGBAPalette: public TObject, public TQObject, public TEveRefCnt


 A generic, speed-optimised mapping from value to RGBA color
 supporting different wrapping and range truncation modes.

 Flag fFixColorRange: specifies how the palette is mapped to signal values:
  true  - LowLimit -> HighLimit
  false - MinValue -> MaxValue

Function documentation

TEveRGBAPalette()
 Constructor.
TEveRGBAPalette(Int_t min, Int_t max, Bool_t interp = kTRUE, Bool_t showdef = kTRUE, Bool_t fixcolrng = kFALSE)
 Constructor.
~TEveRGBAPalette()
 Destructor.
void SetupColor(Int_t val, UChar_t* pix) const
 Set RGBA color 'pixel' for signal-value 'val'.
void SetupColorArray() const
 Construct internal color array that maps signal value to RGBA color.
void ClearColorArray()
 Clear internal color array.
void SetLimits(Int_t low, Int_t high)
 Set low/high limits on signal value. Current min/max values are
 clamped into the new limits.
void SetLimitsScaleMinMax(Int_t low, Int_t high)
 Set low/high limits and rescale current min/max values.
void SetMin(Int_t min)
 Set current min value.
void SetMax(Int_t max)
 Set current max value.
void SetMinMax(Int_t min, Int_t max)
 Set current min/max values.
void SetInterpolate(Bool_t b)
 Set interpolation flag. This determines how colors from ROOT's
 palette are mapped into RGBA values for given signal.
void SetFixColorRange(Bool_t v)
 Set flag specifying how the palette is mapped to signal values:
  true  - LowLimit -> HighLimit
  false - MinValue -> MaxValue
void SetDefaultColor(Color_t ci)
 Set default color.
void SetDefaultColorPixel(Pixel_t pix)
 Set default color.
void SetDefaultColorRGBA(UChar_t r, UChar_t g, UChar_t b, UChar_t a = 255)
 Set default color.
void SetUnderColor(Color_t ci)
 Set underflow color.
void SetUnderColorPixel(Pixel_t pix)
 Set underflow color.
void SetUnderColorRGBA(UChar_t r, UChar_t g, UChar_t b, UChar_t a = 255)
 Set underflow color.
void SetOverColor(Color_t ci)
 Set overflow color.
void SetOverColorPixel(Pixel_t pix)
 Set overflow color.
void SetOverColorRGBA(UChar_t r, UChar_t g, UChar_t b, UChar_t a = 255)
 Set overflow color.
void MinMaxValChanged()
 Emit the "MinMaxValChanged()" signal.
 This is NOT called automatically from SetMin/Max functions but
 it IS called from TEveRGBAPaletteEditor after it changes the
 min/max values.
