Message: 98327 BY: Eddie Du (sjeddie) DATE: 2012-09-05 18:43 SUBJECT: Transparency not working on my Mac. Help!   Here's some code to overlay a transparent square over a blue background - at least I think it should do this. I'm on OSX 10.7.3, ruby 1.9.3p125, RMagick 2.13.1, ImageMagick 6.7.5-7 Code: ########################### require 'RMagick' bg = Magick::Image.new(400, 400) { self.background_color = 'blue' } sq = Magick::Image.new(200, 200) { self.background_color = 'none' } bg.composite!(sq, 0, 0, Magick::OverCompositeOp) bg.write('out.png') ########################### Here's my output: http://i.imgur.com/TKVHr.png Does this happen to you? Any idea what's going on?
