RENDER_LIST

NAME

render_list - renders a list of map tiles by sending requests to a rendering daemon.

SYNOPSIS

render_list [options]<render.list

DESCRIPTION

This manual page briefly documents the render_list command.

render_list is a helper utility that takes a list of map tiles from stdin and sends the requests to a rendering daemon

OPTIONS

This program follows the usual GNU command line syntax, with long options starting with two dashes (‘-’). A summary of options is included below.
-a|--all

Render all tiles in given zoom level range instead of reading from STDIN.

-f|--force

Render tiles even if they seem current.

-m|--map=MAP

Render tiles in this map (defaults to ’default’).

-l|--max-load=LOAD

Sleep if load is this high (defaults to 16).

-s|--socket=SOCKET

Unix domain socket name for contacting renderd.

-n|--num-threads=N

The number of parallel request threads (default 1).

-t|--tile-dir

Tile cache directory (defaults to ’/var/cache/renderd/tiles’).

-z|--min-zoom=ZOOM

Filter input to only render tiles greater or equal to this zoom level (default is 0).

-Z|--max-zoom=ZOOM

Filter input to only render tiles less than or equal to this zoom level (default is 20).

If you are using --all, you can restrict the tile range by adding these options:
-x, --min-x=X minimum X tile coordinate
-X, --max-x=X maximum X tile coordinate
-y, --min-y=Y minimum Y tile coordinate
-Y, --max-y=Y maximum Y tile coordinate

Without --all, send a list of tiles to be rendered from STDIN in the format:
X Y Z
e.g.
0 0 1
0 1 1
1 0 1
1 1 1
The above would cause all 4 tiles at zoom 1 to be rendered
