NAME
Imager::Bing::MapLayer - create a map layer for Bing Maps
SYNOPSIS
my $layer = Imager::Bing::MapLayer->new(
base_dir => $dir, # base directory (default '.')
overwrite => 1, # overwrite existing (default)
autosave => 1, # save on exit (default)
in_memory => 0, # keep tiles in memory (default false)
min_level => 1, # min zoom level (default)
max_level => 19, # max zoom level (default)
combine => 'darken', # tile composition method (default)
);
# Plot polygons (e.g. geographic boundaries)
$layer->polygon(
points => $points, # listref to [ lat, lon ] points
fill => Imager::Fill->new( ... ), #
);
# Plot greyscale gradient circles for heatmaps
$layer->radial_circle(
r => 100, # radius in meters
-min_r => 1, # minimum pixel radius for any zoom level
x => $longitude, # longitude (x = east-west)
y => $latitude, # latitude (y = north-south)
);
# Blur filter
$layer->filter( type => 'gaussian', stddev => 1 );
# Colourise greyscale heatmaps
$layer->colourise();
DESCRIPTION
This module is a wrapper around the Imager::Draw module, which allows
you to create Bing map layers using longitude and latitude coordinates.
The module will automatically map them to the appropriate points on tile
files.
