Python+Mapnik: Changed tile size with generate_tiles.py

Dear forum,

I am new @OSM and have one question regarding tile rendering:

I was able to set up a tile server with postgres data storage and mapnik rendering. Basically I am using the including generate_tiles.py application which works like a charm!

Now I would like to create a mapset with 512x512 pixel tiles instead of 256x256 pixel sized tiles.

Unfortunately I am also new in python and I am not able to get the tiles in correct size :frowning:

(Of couse I tryed to change all “256” to “512” [but png256] in the file - didn’t work.)

Does anybody have an idea?

Many thanks
