Detailed Description

map scalar values into colors via a lookup table

vtkLookupTable is an object that is used by mapper objects to map scalar values into RGBA (red-green-blue-alpha transparency) color specification, or RGBA into scalar values. The color table can be created by direct insertion of color values, or by specifying a hue, saturation, value, and alpha range and generating a table.

A special color for NaN values in the data can be specified via SetNanColor(). In addition, a color for data values below the lookup table range minimum can be specified with SetBelowRangeColor(), and that color will be used for values below the range minimum when UseBelowRangeColor is on. Likewise, a color for data values above the lookup table range maximum can be specified with SetAboveRangeColor(), and it is used when UseAboveRangeColor is on.

This class behaves differently depending on how IndexedLookup is set. When true, vtkLookupTable enters a mode for representing categorical color maps. By setting IndexedLookup to true, you indicate that the annotated values are the only valid values for which entries in the color table should be returned. The colors in the lookup Table are assigned to annotated values by taking the modulus of their index in the list of annotations. IndexedLookup changes the behavior of GetIndex, which in turn changes the way MapScalarsThroughTable2 behaves; when IndexedLookup is true, MapScalarsThroughTable2 will search for scalar values in AnnotatedValues and use the resulting index to determine the color. If a scalar value is not present in AnnotatedValues, then NanColor will be used.

Warning: You need to explicitly call Build() when constructing the LUT by hand.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

Reimplemented in vtkLookupTableWithEnabling, vtkWindowLevelLookupTable, and vtkLogLookupTable.

int vtkLookupTable::IsOpaque ( )

overridevirtual

Return true if all of the values defining the mapping have an opacity equal to 1.

Reimplemented from vtkScalarsToColors.

int vtkLookupTable::Allocate	(	int	sz = `256`,
		int	ext = `256`
	)

Allocate a color table of specified size.

void vtkLookupTable::Build ( )

overridevirtual

Generate lookup table from hue, saturation, value, alpha min/max values.

Table is built from linear ramp of each value.

Reimplemented from vtkScalarsToColors.

Reimplemented in vtkWindowLevelLookupTable.

virtual void vtkLookupTable::ForceBuild ( )

virtual

Force the lookup table to regenerate from hue, saturation, value, and alpha min/max values.

Table is built from a linear ramp of each value. ForceBuild() is useful if a lookup table has been defined manually (using SetTableValue) and then an application decides to rebuild the lookup table using the implicit process.

void vtkLookupTable::BuildSpecialColors ( )

Copies the "special" colors into the given table.

virtual void vtkLookupTable::SetRamp ( int )

virtual

Set the shape of the table ramp to either linear or S-curve.

The default is S-curve, which tails off gradually at either end. The equation used for the S-curve is y = (sin((x - 1/2)*pi) + 1)/2, while the equation for the linear ramp is simply y = x. For an S-curve greyscale ramp, you should set NumberOfTableValues to 402 (which is 256*pi/2) to provide room for the tails of the ramp. The equation for the SQRT is y = sqrt(x).

void vtkLookupTable::SetRampToLinear ( )

inline

Set the shape of the table ramp to either linear or S-curve.

The default is S-curve, which tails off gradually at either end. The equation used for the S-curve is y = (sin((x - 1/2)*pi) + 1)/2, while the equation for the linear ramp is simply y = x. For an S-curve greyscale ramp, you should set NumberOfTableValues to 402 (which is 256*pi/2) to provide room for the tails of the ramp. The equation for the SQRT is y = sqrt(x).

void vtkLookupTable::SetRampToSCurve ( )

inline

Set the shape of the table ramp to either linear or S-curve.
