PNG is an almost-pure-ruby PNG library. It lets you write a PNG without any C libraries. FEATURES * Very simple interface. * Outputs simple PNG files with ease. * Basic PNG reader as well (someday it might do compositing and the like!). * Almost pure ruby, does require a compiler. SYNOPSYS require ‘png’ canvas = PNG::Canvas.new 200, 200 # Set a point to a color canvas[100, 100] = PNG::Color::Black # draw an anti-aliased line canvas.line 50, 50, 100, 50, PNG::Color::Blue png = PNG.new canvas png.save ‘blah.png’
