Detailed Description

SeedConnectivity with user defined seeds.

Date:

Revision:

1.21

Thanks:

Thanks to C. Charles Law who developed this class.

vtkImageSeedConnectivity marks pixels connected to user supplied seeds. The input must be unsigned char, and the output is also unsigned char. If a seed supplied by the user does not have pixel value "InputTrueValue", then the image is scanned +x, +y, +z until a pixel is encountered with value "InputTrueValue". This new pixel is used as the seed . Any pixel with out value "InputTrueValue" is consider off. The output pixels values are 0 for any off pixel in input, "OutputTrueValue" for any pixels connected to seeds, and "OutputUnconnectedValue" for any on pixels not connected to seeds. The same seeds are used for all images in the image set.

Member Function Documentation

vtkImageSeedConnectivity* vtkImageSeedConnectivity::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkImageToImageFilter.

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageToImageFilter.

int vtkImageSeedConnectivity::IsTypeOf (  const char *    type )  [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 vtkImageToImageFilter.

virtual int vtkImageSeedConnectivity::IsA (  const char *    type )  [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 vtkImageToImageFilter.

vtkImageSeedConnectivity* vtkImageSeedConnectivity::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkImageToImageFilter.

void vtkImageSeedConnectivity::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 vtkImageToImageFilter.

void vtkImageSeedConnectivity::RemoveAllSeeds (    )

Methods for manipulating the seed pixels.

void vtkImageSeedConnectivity::AddSeed (  int    num, int *    index )

void vtkImageSeedConnectivity::AddSeed (  int    i0, int    i1, int    i2 )

void vtkImageSeedConnectivity::AddSeed (  int    i0, int    i1 )

virtual void vtkImageSeedConnectivity::SetInputConnectValue (  int    )  [virtual]

Set/Get what value is considered as connecting pixels.

virtual int vtkImageSeedConnectivity::GetInputConnectValue (    )  [virtual]

virtual void vtkImageSeedConnectivity::SetOutputConnectedValue (  int    )  [virtual]

Set/Get the value to set connected pixels to.

virtual int vtkImageSeedConnectivity::GetOutputConnectedValue (    )  [virtual]

virtual void vtkImageSeedConnectivity::SetOutputUnconnectedValue (  int    )  [virtual]

Set/Get the value to set unconnected pixels to.

virtual int vtkImageSeedConnectivity::GetOutputUnconnectedValue (    )  [virtual]

virtual vtkImageConnector* vtkImageSeedConnectivity::GetConnector (    )  [virtual]

Get the vtkImageCOnnector used by this filter.

virtual void vtkImageSeedConnectivity::SetDimensionality (  int    )  [virtual]

Set the number of axes to use in connectivity.

virtual int vtkImageSeedConnectivity::GetDimensionality (    )  [virtual]

void vtkImageSeedConnectivity::operator= (  const vtkImageSeedConnectivity &    )  [inline, protected]

Definition at line 105 of file vtkImageSeedConnectivity.h.

void vtkImageSeedConnectivity::Execute (  vtkImageData *    inData, vtkImageData *    outData )  [protected, virtual]

Reimplemented from vtkImageToImageFilter.

void vtkImageSeedConnectivity::Execute (    )  [inline, protected, virtual]

Reimplemented from vtkImageToImageFilter. Definition at line 115 of file vtkImageSeedConnectivity.h.

void vtkImageSeedConnectivity::Execute (  vtkImageData *    outData )  [inline, protected, virtual]

Reimplemented from vtkImageToImageFilter. Definition at line 116 of file vtkImageSeedConnectivity.h.

void vtkImageSeedConnectivity::EnlargeOutputUpdateExtents (  vtkDataObject *    data )  [protected]

Generate more than requested. Called by the superclass before an execute, and before output memory is allocated.
