colorizer

Get/Set the RasterColorizer used to color data rasters.

Usage:

>>> from mapnik import RasterSymbolizer, RasterColorizer
>>> r = RasterSymbolizer()
>>> r.colorizer = RasterColorizer()
>>> for value, color in [
...     (0, "#000000"),
...     (10, "#ff0000"),
...     (40, "#00ff00"),
... ]:
...      r.colorizer.append_band(value, color)

Set Method:

unreachable(...)

filter_factor

Get/Set the filter factor used by the datasource.

This is used by the Raster or Gdal datasources to pre-downscale
images using overviews.
Higher numbers can sometimes cause much better scaled image
output, at the cost of speed.

Examples:
 -1.0 : (Default) A suitable value will be determined from the
        chosen scaling method during rendering.
  1.0 : The datasource will take care of all the scaling
        (using nearest neighbor interpolation)
  2.0 : The datasource will scale the datasource to
        2.0x the desired size, and mapnik will scale the rest
        of the way using the interpolation defined in self.scaling.

mesh_size

Get/Set warping mesh size. Larger values result in faster warping times but might result in distorted maps.

Usage:

>>> from mapnik import RasterSymbolizer
>>> r = RasterSymbolizer()
>>> r.mesh_size = 32

mode

Get/Set merging mode. Possible values are: normal, grain_merge, grain_merge2, multiply, multiply2, divide, divide2, screen, and hard_light

Usage:

>>> from mapnik import RasterSymbolizer
>>> r = RasterSymbolizer()
>>> r.mode = 'grain_merge2'

opacity

Get/Set opacity.

Usage:

>>> from mapnik import RasterSymbolizer
>>> r = RasterSymbolizer()
>>> r.opacity = .5

scaling

Get/Set scaling algorithm. Possible values are: fast, bilinear, and bilinear8

Usage:

>>> from mapnik import RasterSymbolizer
>>> r = RasterSymbolizer()
>>> r.scaling = 'bilinear8'
