Imager-Heatmap version 0.03 =========================== Imager::Heatmap - Perl extension for drawing Heatmap using Imager SYNOPSIS use Imager::Heatmap; my $hmap = Imager::Heatmap->new( xsize => 640, # Image width ysize => 480, # Image height xsigma => 10, # Sigma value of X-direction. ysigma => 10, # Sigma value of Y-direction. ); # Add point datas to construct density matrix $hmap->insert_datas(@piont_datas); # @point_datas should be: ( [ x1, y1, weight1 ], [ x2, y2, weight2 ] ... ) $hmap->insert_datas(...); # You can call multiple times to add large data that cannot process at a time. # After adding datas, you could get heatmap as Imager instance. my $img = $hmap->draw; DESCRIPTION Imager::Heatmap is a module to draw heatmap using Imager. This module calculates probability density matrix from input data and map a color for each pixels to represent density of input data.
