Detailed Description

magnify an image by an integer value.

Date:

2000/12/10 20:09:08

Revision:

1.27

Thanks:

Thanks to C. Charles Law who developed this class.

vtkImageMagnify maps each pixel of the input onto a nxmx... region of the output. Location (0,0,...) remains in the same place. The magnification occurs via pixel replication, or if Interpolate is on, by bilinear interpolation.

Member Function Documentation

vtkImageMagnify* vtkImageMagnify::New (    )  [static]

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

virtual const char* vtkImageMagnify::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 vtkImageMagnify::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 vtkImageMagnify::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.

vtkImageMagnify* vtkImageMagnify::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 vtkImageMagnify::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 vtkImageMagnify::SetMagnificationFactors (  int   , int   , int    )  [virtual]

Set/Get the integer magnification factors in the i-j-k directions.

virtual void vtkImageMagnify::SetMagnificationFactors (  int   [3] )  [virtual]

virtual int* vtkImageMagnify::GetMagnificationFactors (    )  [virtual]

virtual void vtkImageMagnify::GetMagnificationFactors (  int &   , int &   , int &    )  [virtual]

virtual void vtkImageMagnify::GetMagnificationFactors (  int   [3] )  [virtual]

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

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

virtual int vtkImageMagnify::GetInterpolate (    )  [virtual]

virtual void vtkImageMagnify::InterpolateOn (    )  [virtual]

virtual void vtkImageMagnify::InterpolateOff (    )  [virtual]

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

Definition at line 82 of file vtkImageMagnify.h.

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

Reimplemented from vtkImageToImageFilter.

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

Reimplemented from vtkImageToImageFilter.

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

Reimplemented from vtkImageToImageFilter. Definition at line 88 of file vtkImageMagnify.h.

void vtkImageMagnify::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.
