Detailed Description

a combination of vtkColorTransferFunction and vtkLookupTable.

This is a cross between a vtkColorTransferFunction and a vtkLookupTable selectively combining the functionality of both. This class is a vtkColorTransferFunction allowing users to specify the RGB control points that control the color transfer function. At the same time, by setting Discretize to 1 (true), one can force the transfer function to only have NumberOfValues discrete colors.

When IndexedLookup is true, this class behaves differently. The annotated values are considered to the be only valid values for which entries in the color table should be returned. The colors for annotated values are those specified using AddIndexedColors. Typically, there must be at least as many indexed colors specified as the annotations. For backwards compatibility, if no indexed-colors are specified, the colors in the lookup Table are assigned to annotated values by taking the modulus of their index in the list of annotations. If a scalar value is not present in AnnotatedValues, then NanColor will be used.

One can set a scalar opacity function to map scalars to color types handling transparency (VTK_RGBA, VTK_LUMINANCE_ALPHA). Opacity mapping is off by default. Call EnableOpacityMappingOn() to handle mapping of alpha values.

NOTE: One must call Build() after making any changes to the points in the ColorTransferFunction to ensure that the discrete and non-discrete versions match up.

◆ SetIndexedColorRGB()

void vtkDiscretizableColorTransferFunction::SetIndexedColorRGB	(	unsigned int	index,
		const double	rgb[3]
	)

inline

Add colors to use when IndexedLookup is true.

SetIndexedColor() will automatically call SetNumberOfIndexedColors(index+1) if the current number of indexed colors is not sufficient for the specified index and all will be initialized to the RGBA/RGB values passed to this call.

◆ GetIndexedColor()

void vtkDiscretizableColorTransferFunction::GetIndexedColor	(	vtkIdType	i,
		double	rgba[4]
	)

overridevirtual

Get the "indexed color" assigned to an index.

The index is used in IndexedLookup mode to assign colors to annotations (in the order the annotations were set). Subclasses must implement this and interpret how to treat the index. vtkLookupTable simply returns GetTableValue(index % this->GetNumberOfTableValues()). vtkColorTransferFunction returns the color associated with node index % this->GetSize().

Note that implementations must set the opacity (alpha) component of the color, even if they do not provide opacity values in their colormaps. In that case, alpha = 1 should be used.

Reimplemented from vtkColorTransferFunction.

◆ SetNumberOfIndexedColors()

void vtkDiscretizableColorTransferFunction::SetNumberOfIndexedColors ( unsigned int count )

Set the number of indexed colors.

These are used when IndexedLookup is true. If no indexed colors are specified, for backwards compatibility, this class reverts to using the RGBPoints for colors.

These are used when IndexedLookup is true. If no indexed colors are specified, for backwards compatibility, this class reverts to using the RGBPoints for colors.
