Render to PDF about node-mapnik HOT 5 CLOSED

okay, wscript has now been fixed up to auto-detect if mapnik has cairo support and then builds node-mapnik with cairo support for the map.render_to_file() function.

Call it like:

map.render_to_file('map.pdf',{format:'pdf'})

or just:

map.render_to_file('map.pdf') // should also work

from node-mapnik.

Works great. Next step here would be to allow async rendering to PDF as well but this is a lower priority.

glad it works. Are you checking if mapnik.supports.cairo == true ?

regarding async, I could expose a async render_to_file, but an async render() (e.g to buffer) would be tough since mapnik does not properly expose writing cairo surfaces to streams (in fact not sure if cairo supports this). I assume either would be fine? e.g. do you think you specifically need a PDF as a buffer or just need to push to the filesystem?

Yep, I am using mapnik.supports which is pretty awesome.

In this case (and I imagine most others) I don't need PDF as a buffer, it will definitely just be written to disk when all is said and done.
