add_stop( (RasterColorizer)arg1, (ColorizerStop)ColorizerStop) -> None :
    Add a colorizer stop to the raster colorizer.
    
    Usage:
    >>> colorizer = mapnik.RasterColorizer()
    >>> color = mapnik.Color("#0044cc")
    >>> stop = mapnik.ColorizerStop(3, mapnik.COLORIZER_INHERIT, color)
    >>> colorizer.add_stop(stop)
    

    C++ signature :
        void add_stop(boost::shared_ptr<mapnik::raster_colorizer> {lvalue},mapnik::colorizer_stop {lvalue})

add_stop( (RasterColorizer)arg1, (float)value) -> None :
    Add a colorizer stop to the raster colorizer, using the default mode and color.
    
    Usage:
    >>> default_color = mapnik.Color("#0044cc")
    >>> colorizer = mapnik.RasterColorizer(mapnik.COLORIZER_LINEAR, default_color)
    >>> colorizer.add_stop(100)
    

    C++ signature :
        void add_stop(boost::shared_ptr<mapnik::raster_colorizer> {lvalue},float)

add_stop( (RasterColorizer)arg1, (float)arg2, (Color)value) -> None :
    Add a colorizer stop to the raster colorizer, using the default mode.
    
    Usage:
    >>> default_color = mapnik.Color("#0044cc")
    >>> colorizer = mapnik.RasterColorizer(mapnik.COLORIZER_LINEAR, default_color)
    >>> colorizer.add_stop(100, mapnik.Color("#123456"))
    

    C++ signature :
        void add_stop(boost::shared_ptr<mapnik::raster_colorizer> {lvalue},float,mapnik::color)

add_stop( (RasterColorizer)arg1, (float)arg2, (ColorizerMode)value) -> None :
    Add a colorizer stop to the raster colorizer, using the default color.
    
    Usage:
    >>> default_color = mapnik.Color("#0044cc")
    >>> colorizer = mapnik.RasterColorizer(mapnik.COLORIZER_LINEAR, default_color)
    >>> colorizer.add_stop(100, mapnik.COLORIZER_EXACT)
    

    C++ signature :
        void add_stop(boost::shared_ptr<mapnik::raster_colorizer> {lvalue},float,mapnik::colorizer_mode_enum)

add_stop( (RasterColorizer)arg1, (float)arg2, (ColorizerMode)arg3, (Color)value) -> None :
    Add a colorizer stop to the raster colorizer.
    
    Usage:
    >>> default_color = mapnik.Color("#0044cc")
    >>> colorizer = mapnik.RasterColorizer(mapnik.COLORIZER_LINEAR, default_color)
    >>> colorizer.add_stop(100, mapnik.COLORIZER_DISCRETE, mapnik.Color("#112233"))

get_color( (RasterColorizer)arg1, (float)arg2) -> Color :
    Get the color assigned to a certain value in raster data.
    
    Usage:
    >>> colorizer = mapnik.RasterColorizer()
    >>> color = mapnik.Color("#0044cc")
    >>> colorizer.add_stop(0, mapnik.COLORIZER_DISCRETE, mapnik.Color("#000000"))

default_color

The default color for stops added without a color (mapnik.Color).

Get Method:

unreachable(...)

Set Method:

unreachable(...)

default_mode

The default mode (mapnik.ColorizerMode).

If a stop is added without a mode, then it will inherit this default mode

Get Method:

unreachable(...)

Set Method:

unreachable(...)

epsilon

Comparison epsilon value for exact mode

When comparing values in exact mode, values need only be within epsilon to match.

Get Method:

unreachable(...)

Set Method:

unreachable(...)

stops

The list of stops this RasterColorizer contains

Get Method:
