Detailed Description

Generic image filter with one input.

vtkSimpleImageToImageFilter is a filter which aims to avoid much of the complexity associated with vtkImageAlgorithm (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 vtkSimpleImageToImageFilter.

Member Function Documentation

virtual const char* vtkSimpleImageToImageFilter::GetClassName (  )  [virtual]

Reimplemented from vtkImageAlgorithm.

Reimplemented in vtkSimpleImageFilterExample.

static int vtkSimpleImageToImageFilter::IsTypeOf ( const char *  name  )  [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 vtkImageAlgorithm.

Reimplemented in vtkSimpleImageFilterExample.

virtual int vtkSimpleImageToImageFilter::IsA ( const char *  name  )  [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 vtkImageAlgorithm.

Reimplemented in vtkSimpleImageFilterExample.

static vtkSimpleImageToImageFilter* vtkSimpleImageToImageFilter::SafeDownCast ( vtkObject o  )  [static]

Reimplemented from vtkImageAlgorithm.

Reimplemented in vtkSimpleImageFilterExample.

void vtkSimpleImageToImageFilter::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 vtkImageAlgorithm.

virtual int vtkSimpleImageToImageFilter::RequestUpdateExtent ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
) [protected, virtual]

Reimplemented from vtkImageAlgorithm.

virtual int vtkSimpleImageToImageFilter::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
) [protected, virtual]

This is called by the superclass. This is the method you should override.

Reimplemented from vtkImageAlgorithm.

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

Implemented in vtkSimpleImageFilterExample.
