Detailed Description

Create an image filled with noise.

Date:

2000/12/10 20:09:09

Revision:

1.17

Thanks:

Thanks to C. Charles Law who developed this class.

vtkImageNoiseSource just produces images filled with noise. The only option now is uniform noise specified by a min and a max. There is one major problem with this source. Every time it executes, it will output different pixel values. This has important implications when a stream requests overlapping regions. The same pixels will have different values on different updates.

Member Function Documentation

vtkImageNoiseSource* vtkImageNoiseSource::New (    )  [static]

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

virtual const char* vtkImageNoiseSource::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.

int vtkImageNoiseSource::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.

virtual int vtkImageNoiseSource::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.

vtkImageNoiseSource* vtkImageNoiseSource::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.

void vtkImageNoiseSource::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 vtkSource.

virtual void vtkImageNoiseSource::SetMinimum (  float    )  [virtual]

Set/Get the minimum and maximum values for the generated noise.

virtual float vtkImageNoiseSource::GetMinimum (    )  [virtual]

virtual void vtkImageNoiseSource::SetMaximum (  float    )  [virtual]

virtual float vtkImageNoiseSource::GetMaximum (    )  [virtual]

void vtkImageNoiseSource::SetWholeExtent (  int    xMinx, int    xMax, int    yMin, int    yMax, int    zMin, int    zMax )

Set how large of an image to generate.

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

Definition at line 86 of file vtkImageNoiseSource.h.

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

Reimplemented from vtkSource.

void vtkImageNoiseSource::Execute (  vtkImageData *    data )  [protected, virtual]

Reimplemented from vtkImageSource.

void vtkImageNoiseSource::Execute (    )  [inline, protected, virtual]

Reimplemented from vtkImageSource. Definition at line 94 of file vtkImageNoiseSource.h.
