#include <vtkAreaLayout.h>
vtkAreaLayout assigns sector regions to each vertex in the tree, creating a tree ring. The data is added as a data array with four components per tuple representing the location and size of the sector using the format (StartAngle, EndAngle, innerRadius, outerRadius).
This algorithm relies on a helper class to perform the actual layout. This helper class is a subclass of vtkAreaLayoutStrategy.

static vtkAreaLayout* vtkAreaLayout::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkTreeAlgorithm.
virtual const char* vtkAreaLayout::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkTreeAlgorithm.
static int vtkAreaLayout::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 vtkTreeAlgorithm.
virtual int vtkAreaLayout::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 vtkAreaLayout::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 vtkTreeAlgorithm.
virtual void vtkAreaLayout::SetSizeArrayName | ( | const char * | name | ) | [inline, virtual] |
The array name to use for retrieving the relative size of each vertex. If this array is not found, use constant size for each vertex.

virtual char* vtkAreaLayout::GetAreaArrayName | ( | ) | [virtual] |
The name for the array created for the area for each vertex. The rectangles are stored in a quadruple float array (startAngle, endAngle, innerRadius, outerRadius). For rectangular layouts, this is (minx, maxx, miny, maxy).
virtual void vtkAreaLayout::SetAreaArrayName | ( | const char * | ) | [virtual] |
The name for the array created for the area for each vertex. The rectangles are stored in a quadruple float array (startAngle, endAngle, innerRadius, outerRadius). For rectangular layouts, this is (minx, maxx, miny, maxy).
virtual bool vtkAreaLayout::GetEdgeRoutingPoints | ( | ) | [virtual] |
Whether to output a second output tree with vertex locations appropriate for routing bundled edges. Default is on.
