render_list1

Usage

Overview

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.

-c|--config=CONFIG

Specify a `renderd.conf` file from which to load various option values rather than specifying via command line.

The following options will be set (if present); however, they can be overridden if also specified:

-s|--socket

-n|--num-threads

-t|--tile-dir

-z|--min-zoom

-Z|--max-zoom

-f|--force

Render tiles even if they seem current.

-m|--map=MAP

Render tiles in this map (default is 'default').

-l|--max-load=LOAD

Sleep if load is this high (default is '16').

-s|--socket=SOCKET|HOSTNAME:PORT

Unix domain socket name or hostname and port for contacting renderd (default is '/run/renderd/renderd.sock').

-n|--num-threads=N

The number of parallel request threads (default is '1').

-t|--tile-dir=TILE_DIR

Tile cache directory (default is '/var/cache/renderd/tiles').

-z|--min-zoom=ZOOM

Filter input to only render tiles greater than 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').

-h|--help

Print out a help text for render_list

-V|--version

Print out the version number for render_list

If you are using -a|--all, you can restrict the tile range by adding these options:

(please note that tile coordinates must be positive integers and are not latitude and longitude values)

-g|--min-lat=LATITUDE minimum latitude
-G|--max-lat=LATITUDE maximum latitude
-w|--min-lon=LONGITUDE minimum longitude
-W|--max-lon=LONGITUDE maximum longitude
-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 -a|--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
