Detailed Description

Resamples an image to be larger or smaller.

Date:

2000/12/10 20:09:10

Revision:

1.26

Thanks:

Thanks to C. Charles Law who developed this class.

This filter produces an output with different spacing (and extent) than the input. Linear interpolation can be used to resample the data. The Output spacing can be set explicitly or relative to input spacing with the SetAxisMagnificationFactor method.

Member Function Documentation

vtkImageResample* vtkImageResample::New (    )  [static]

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

virtual const char* vtkImageResample::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 vtkImageResample::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 vtkImageResample::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.

vtkImageResample* vtkImageResample::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 vtkImageResample::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 vtkImageResample::SetAxisOutputSpacing (  int    axis, float    spacing )

Set desired spacing. Zero is a reserved value indicating spacing has not been set.

void vtkImageResample::SetAxisMagnificationFactor (  int    axis, float    factor )

Set/Get Magnification factors. Zero is a reserved value indicating values have not been computed.

float vtkImageResample::GetAxisMagnificationFactor (  int    axis )

virtual void vtkImageResample::SetInterpolate (  int    )  [virtual]

Turn interpolation on and off (pixel replication is used when off).

virtual int vtkImageResample::GetInterpolate (    )  [virtual]

virtual void vtkImageResample::InterpolateOn (    )  [virtual]

virtual void vtkImageResample::InterpolateOff (    )  [virtual]

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

Dimensionality is the number of axes which are considered during execution. To process images dimensionality would be set to 2. This has the same effect as setting the output spacing of the third axis to 1.0

virtual int vtkImageResample::GetDimensionality (    )  [virtual]

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

Definition at line 94 of file vtkImageResample.h.

void vtkImageResample::ComputeInputUpdateExtent (  int    inExt[6], int    outExt[6] )  [protected, virtual]

Reimplemented from vtkImageToImageFilter.

void vtkImageResample::ExecuteInformation (  vtkImageData *    inData, vtkImageData *    outData )  [protected, virtual]

Reimplemented from vtkImageToImageFilter.

void vtkImageResample::ExecuteInformation (    )  [inline, protected, virtual]

Reimplemented from vtkImageToImageFilter. Definition at line 103 of file vtkImageResample.h.

void vtkImageResample::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.
