Detailed Description

performs line-based thresholding for vtkTable data.

Class for filtering the rows of a two numeric columns of a vtkTable. The columns are treated as the two variables of a line. This filter will then iterate through the rows of the table determining if X,Y values pairs are above/below/between/near one or more lines.

The "between" mode checks to see if a row is contained within the convex hull of all of the specified lines. The "near" mode checks if a row is within a distance threshold two one of the specified lines. This class is used in conjunction with various plotting classes, so it is useful to rescale the X,Y axes to a particular range of values. Distance comparisons can be performed in the scaled space by setting the CustomRanges ivar and enabling UseNormalizedDistance.

Member Function Documentation

static vtkBivariateLinearTableThreshold* vtkBivariateLinearTableThreshold::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkTableAlgorithm.

Reimplemented in vtkPBivariateLinearTableThreshold.

virtual const char* vtkBivariateLinearTableThreshold::GetClassName ( ) [virtual]

Reimplemented from vtkTableAlgorithm.

Reimplemented in vtkPBivariateLinearTableThreshold.

static int vtkBivariateLinearTableThreshold::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkTableAlgorithm.

Reimplemented in vtkPBivariateLinearTableThreshold.

virtual int vtkBivariateLinearTableThreshold::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkTableAlgorithm.

void vtkBivariateLinearTableThreshold::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)			`[virtual]`

Methods invoked by print to print information about the object including superclasses. 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 vtkTableAlgorithm.

Reimplemented in vtkPBivariateLinearTableThreshold.

virtual void vtkBivariateLinearTableThreshold::SetInclusive ( int ) [virtual]

Include the line in the threshold. Essentially whether the threshold operation uses > versus >=.
