Compare all of the images on an HTML page and sort them according to how well they represent what the page is about. The top image could be used as a thumbnail to represent the entire page.
Basic usage:
require 'plumnailer'
chooser = Plumnailer::Chooser.new
choice = chooser.choose('http://urls.matthewm.boedicker.org/')
puts choice.source_url
choice.resize_to_fill(64, 64).write('thumb.jpg')Alternate fetcher that caches images on local filesystem:
require 'plumnailer'
chooser = Plumnailer::Chooser.new
chooser.fetcher = chooser.img_parser.fetcher =
Plumnailer::CachingFetcher.new('/tmp/plumnailer-test')
choice = chooser.choose('http://urls.matthewm.boedicker.org/')
puts choice.source_urlTop five images:
require 'plumnailer'
chooser = Plumnailer::Chooser.new
chooser.choose('http://urls.matthewm.boedicker.org/', :top => 5).each do |i|
puts i.source_url
