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.
Examples:

Member Function Documentation

void vtkImageSeedConnectivity::EnlargeOutputUpdateExtents vtkDataObject   data [protected]
 

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

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.

virtual vtkImageConnector* vtkImageSeedConnectivity::GetConnector   [virtual]
 

Get the vtkImageCOnnector used by this filter.

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.

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.

vtkImageSeedConnectivity* vtkImageSeedConnectivity::New   [static]
 

Instantiate object with no start, end, or progress methods.

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.

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.

virtual void vtkImageSeedConnectivity::SetDimensionality int    [virtual]
 

Set the number of axes to use in connectivity.

virtual void vtkImageSeedConnectivity::SetInputConnectValue int    [virtual]
 

Set/Get what value is considered as connecting pixels.

virtual void vtkImageSeedConnectivity::SetOutputConnectedValue int    [virtual]
 

Set/Get the value to set connected pixels to.

virtual void vtkImageSeedConnectivity::SetOutputUnconnectedValue int    [virtual]
 

Set/Get the value to set unconnected pixels to.
