Detailed Description

Passes each pixel through log function.

Date:

2001/11/13 14:32:37

Revision:

1.20

Thanks:

Thanks to C. Charles Law who developed this class.

vtkImageLogarithmicScale passes each pixel through the function c*log(1+x). It also handles negative values with the function -c*log(1-x).

Member Function Documentation

vtkImageLogarithmicScale* vtkImageLogarithmicScale::New (    )  [static]

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

virtual const char* vtkImageLogarithmicScale::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 vtkImageLogarithmicScale::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 vtkImageLogarithmicScale::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.

vtkImageLogarithmicScale* vtkImageLogarithmicScale::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 vtkImageLogarithmicScale::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 vtkImageLogarithmicScale::SetConstant (  float    )  [virtual]

Set/Get the scale factor for the logarithmic function.

virtual float vtkImageLogarithmicScale::GetConstant (    )  [virtual]

Set/Get the scale factor for the logarithmic function.

void vtkImageLogarithmicScale::ThreadedExecute (  vtkImageData *    inData, vtkImageData *    outData, int    outExt[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.
