Description

Small wrapper for the Mapnik 3 API to render beautiful maps from Go.

Features:

  • Render to []byte, image.Image, or file.
  • Set scale denominator or scale factor.
  • Enable/disable single layers.

Installation

This package requires Mapnik (libmapnik-dev on Ubuntu/Debian, mapnik in Homebrew). Make sure mapnik-config is in your PATH.

You need to set the CGO_LDFLAGS and CGO_CXXFLAGS environment variables for successful compilation and linking with Mapnik. Refer to the Makefile how mapnik-config can be used to extract the required CGO_LDFLAGS and CGO_CXXFLAGS values. Use -ldflags to overwrite the default location of the input plugins and default fonts.
