Thanks to C. Charles Law who developed this class.

vtkSimpleImageToImageFilter is a filter which aims to avoid much of the complexity associated with vtkImageToImageFilter (i.e. support for pieces, multi-threaded operation). If you need to write a simple image-image filter which operates on the whole input, use this as the superclass. The subclass has to provide only an execute method which takes input and output as arguments. Memory allocation is handled in vtkSimpleImageToImageFilter. Also, you are guaranteed to have a valid input in the Execute(input, output) method. By default, this filter requests it's input's whole extent and copies the input's information (spacing, whole extent etc...) to the output. If the output's setup is different (for example, if it performs some sort of sub-sampling), ExecuteInformation has to be overwritten. As an example of how this can be done, you can look at vtkImageShrink3D::ExecuteInformation. For a complete example which uses templates to support generic data types, see vtkSimpleFilterExample.

Member Function Documentation

virtual const char* vtkSimpleImageToImageFilter::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 vtkImageSource. Reimplemented in vtkSimpleImageFilterExample.

int vtkSimpleImageToImageFilter::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 vtkImageSource. Reimplemented in vtkSimpleImageFilterExample.

virtual int vtkSimpleImageToImageFilter::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 vtkImageSource. Reimplemented in vtkSimpleImageFilterExample.

vtkSimpleImageToImageFilter* vtkSimpleImageToImageFilter::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 vtkImageSource. Reimplemented in vtkSimpleImageFilterExample.

virtual void vtkSimpleImageToImageFilter::SetInput (  vtkImageData *    input )  [virtual]

Set the Input of a filter.

vtkImageData* vtkSimpleImageToImageFilter::GetInput (    )

Set the Input of a filter.

virtual void vtkSimpleImageToImageFilter::ExecuteInformation (    )  [protected, virtual]

Reimplemented from vtkSource.

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

virtual void vtkSimpleImageToImageFilter::ExecuteData (  vtkDataObject *    output )  [protected, virtual]

virtual void vtkSimpleImageToImageFilter::SimpleExecute (  vtkImageData *    input, vtkImageData *    output )  [protected, pure virtual]

Reimplemented in vtkSimpleImageFilterExample.
