You are here: Rasters > MapnikRasterizer


Draws input point, line, polygon, and raster features onto a raster using the Mapnik toolkit.

Mapnik divides features into groups called layers. Features in a layer should share the same geometry type. For each layer, one or more symbolizers will be defined; these represent a set of parameters that describe how to render the features. For example, a layer could be a set of lines representing country borders. This layer could then have two symbolizers -- one to draw the lines, and a second one to draw a "glow" surrounding the lines.

Input Ports

This transformer will have one input port for each layer. Layers are defined using the Inputs parameter.
