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.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter.
