Mapnik to image export

Nik4 is a mapnik-to-image exporting script using the Mapnik Python bindings.

Nik4 takes great care to preserve values you feed it. If you say you need a 800x600 image, it won't take a pixel less or more. It won't shrink a bounding box or distort lines when specifying so called "scale factor". When you need a 300 dpi image, you tell it --ppi 300 and can be sure you will get what you intended.

Also it can use real-world units, that is, millimeters (and prefers to). Specify dimensions for printing, choose bounding box and ppi scale - and the result won't disappoint. Options are intuitive and plenty, and you will be amazed how much tasks became simpler with Nik4.
