Detailed Description

generalized histograms up to 4 dimensions

Date:

Revision:
1.27

vtkImageQuantizeRGBToIndex takes a 3 component RGB image as input and produces a one component index image as output, along with a lookup table that contains the color definitions for the index values. This filter works on the entire input extent - it does not perform streaming, and it does not supported threaded execution (because it has to process the entire image).

To use this filter, you typically set the number of colors (between 2 and 65536), execute it, and then retrieve the lookup table. The colors can then be using the lookup table and the image index.

Member Function Documentation

vtkImageQuantizeRGBToIndex* vtkImageQuantizeRGBToIndex::New   [static]
 

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkImageQuantizeRGBToIndex::GetClassName   [virtual]
 

Reimplemented from vtkImageToImageFilter.

int vtkImageQuantizeRGBToIndex::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkImageToImageFilter.

virtual int vtkImageQuantizeRGBToIndex::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 vtkTypeRevisionMacro found in vtkSetGet.h.

[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 vtkImageQuantizeRGBToIndex::SetNumberOfColors int    [virtual]
 

Set / Get the number of color index values to produce - must be a number between 2 and 65536.
