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.
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.
