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.
