Detailed Description

Implements pixel-wise intensity->rgb mapping operation on one image.

This class is parameterized over the type of the input image and the type of the output image.

The input image's scalar pixel values are mapped into a color map. The color map is specified by passing the SetColormap function one of the predefined maps. The following selects the "Hot" colormap:

RGBFilterType::Pointer colormapImageFilter = RGBFilterType::New();
 
colormapImageFilter->SetColormap( RGBFilterType::Hot );

You can also specify a custom color map. This is done by creating a CustomColormapFunction, and then creating lists of values for the red, green, and blue channel. An example of setting the red channel of a colormap with only 2 colors is given below. The blue and green channels should be specified in the same manner.

// Create the custom colormap
 
typedef itk::Function::CustomColormapFunction <RealImageType::PixelType,
 
RGBImageType::PixelType> ColormapType ;
 
ColormapType::Pointer colormap = ColormapType::New ();
 
// Setup the red channel of the colormap
 
ColormapType::ChannelType redChannel;
 
redChannel.push_back(0); redChannel.push_back(255);
 
colormap->SetRedChannel( channel );

The range of values present in the input image is the range that is mapped to the entire range of colors.
