Detailed Description

Computes magnitude of the gradient.

Thanks:
Thanks to C. Charles Law who developed this class.
vtkImageGradientMagnitude computes the gradient magnitude of an image. Setting the dimensionality determines whether the gradient is computed on 2D images, or 3D volumes. The default is two dimensional XY images. OutputScalarType is always float.

Member Function Documentation

vtkImageGradientMagnitude* vtkImageGradientMagnitude::New   [static]
 

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

Reimplemented from vtkImageToImageFilter.

virtual const char* vtkImageGradientMagnitude::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 vtkImageGradientMagnitude::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 vtkImageGradientMagnitude::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.

vtkImageGradientMagnitude* vtkImageGradientMagnitude::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 vtkImageGradientMagnitude::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.

virtual void vtkImageGradientMagnitude::SetHandleBoundaries int    [virtual]
 

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual int vtkImageGradientMagnitude::GetHandleBoundaries   [virtual]
 

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual void vtkImageGradientMagnitude::HandleBoundariesOn   [virtual]
 

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual void vtkImageGradientMagnitude::HandleBoundariesOff   [virtual]
 

If "HandleBoundariesOn" then boundary pixels are duplicated So central differences can get values.

virtual void vtkImageGradientMagnitude::SetDimensionality int    [virtual]
 

Determines how the input is interpreted (set of 2d slices ...)

virtual int vtkImageGradientMagnitude::GetDimensionality   [virtual]
 

Determines how the input is interpreted (set of 2d slices ...)

void vtkImageGradientMagnitude::ExecuteInformation vtkImageData   inData,
vtkImageData   outData
[protected, virtual]
 

Reimplemented from vtkImageToImageFilter.

void vtkImageGradientMagnitude::ComputeInputUpdateExtent int    inExt[6],
int    outExt[6]
[protected, virtual]
 

Reimplemented from vtkImageToImageFilter.

void vtkImageGradientMagnitude::ExecuteInformation   [inline, protected, virtual]
 

Reimplemented from vtkImageToImageFilter.

Definition at line 99 of file vtkImageGradientMagnitude.h.

void vtkImageGradientMagnitude::ThreadedExecute vtkImageData   inData,
vtkImageData   outData,
int    extent[6],
int    id
[protected, virtual]
 

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.

Reimplemented from vtkImageToImageFilter.
