#include <vtkExtractSelectedThresholds.h>
Detailed Description
extract a cells or points from a dataset that have values within a set of thresholds.
vtkExtractSelectedThresholds extracts all cells and points with attribute values that lie within a vtkSelection's THRESHOLD contents. The selecion can specify to threshold a particular array within either the point or cell attribute data of the input. This is similar to vtkThreshold but allows mutliple thresholds ranges. This filter adds a scalar array called vtkOriginalCellIds that says what input cell produced each output cell. This is an example of a Pedigree ID which helps to trace back results.

Member Function Documentation
| static int vtkExtractSelectedThresholds::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 vtkExtractSelectionBase.
| virtual int vtkExtractSelectedThresholds::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.

| void vtkExtractSelectedThresholds::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.

| static int vtkExtractSelectedThresholds::EvaluateValue | ( | vtkDataArray * | scalars, |
| vtkIdType | id, | ||
| vtkDataArray * | lims | ||
| ) | [inline, static] |
Function for determining whether a value in a data array passes the threshold test(s) provided in lims. Returns 1 if the value passes at least one of the threshold tests. If scalars is NULL, then the id itself is used as the scalar value.
Definition at line 57 of file vtkExtractSelectedThresholds.h.
| static int vtkExtractSelectedThresholds::EvaluateValue | ( | vtkDataArray * | array, |
| int | array_component_no, | ||
| vtkIdType | id, | ||
| vtkDataArray * | lims | ||
| ) | [static] |
Same as the other EvaluateValue except that the component to be compared can be picked using array_component_no (use -1 for magnitude). If scalars is NULL, then the id itself is used as the scalar value.

| int * | BelowCount, | ||
| int * | InsideCount | ||
| ) | [inline, static] |
Function for determining whether a value in a data array passes the threshold test(s) provided in lims. Returns 1 if the value passes at least one of the threshold tests. Also returns in AboveCount, BelowCount and InsideCount the number of tests where the value was above, below or inside the interval. If scalars is NULL, then the id itself is used as the scalar value.
