ColorMap
Namespace: DISPLIB · Library: Display Library
#include <disp/colormap.h>
class DISPLIB::ColorMap
Static lookup helpers mapping scalar values to QRgb / QColor across all DISPLIB palettes.
Each palette exists as a 256-row Eigen::MatrixX3i RGB table; the valueToXxx accessors interpolate between rows so callers can map any value in to a colour without instantiating an object. Bundled palettes include Viridis, Jet, Hot, HotNeg1, HotNeg2, Bone, Cool, RedBlue and the MNE-Python hot variant.
Public Methods
ColorMap()
Default constructor.
~ColorMap()
Destructs the ColorMap class.
Static Methods
valueToColor(v, sMap)
Returns a Jet RGB to a given double value [0,1] and a colormap specified by sMap.
If no matching colormap was found return Jet.
Parameters:
-
v : double the double which has to be part of the intervall [0,1].
-
sMap : const QString & the colormap to choose.
Returns:
- QRgb — the corresponding RGB value.
valueToJet(v)
Returns a Jet RGB to a given double value [0,1].
Parameters:
- v : double the double which has to be part of the intervall [0,1].
Returns:
- QRgb — the corresponding Jet RGB.
valueToHot(v)
Returns a Hot RGB to a given double value [0,1].
Parameters:
- v : double the double which has to be part of the intervall [0,1].
Returns:
- QRgb — the corresponding Hot RGB.
valueToHotNegative1(v)
Returns a negative skewed hot RGB to a given double value [0,1].
Parameters:
- v : double the double which has to be part of the intervall [0,1].
Returns:
- QRgb — the corresponding negative skewed Hot RGB.
valueToHotNegative2(v)
Returns a negative skewed hot RGB to a given double value [0,1].
Parameters:
- v : double the double which has to be part of the intervall [0,1].
Returns:
- QRgb — the corresponding negative skewed Hot RGB.
valueToBone(v)
Returns a Bone RGB to a given double value [0,1].
Parameters:
- v : double the double which has to be part of the intervall [0,1].
Returns:
- QRgb — the corresponding Bone RGB.
valueToRedBlue(v)
Returns a RedBlue RGB to a given double value [-1,1].
Parameters:
- v : double the double which has to be part of the intervall [-1,1].
Returns:
- QRgb — the corresponding Bone RGB.
valueToCool(v)
Returns a Cool RGB to a given double value [-1,1].
Parameters:
- v : double the double which has to be part of the intervall [-1,1].
Returns:
- QRgb — the corresponding Cool RGB.
valueToViridis(v)
Returns a Viridis RGB to a given double value [-1,1].
Parameters:
- v : double the double which has to be part of the intervall [-1,1].
Returns:
- QRgb — the corresponding Cool RGB.
valueToViridisNegated(v)
Returns a negated Viridis RGB to a given double value [-1,1].
Parameters:
- v : double the double which has to be part of the intervall [-1,1].
Returns:
- QRgb — the corresponding Cool RGB.
