# DON'T WORK ON WINDOWS (Only on *nix Terminal)



module UnixConsoleStyler

  class StyleNotFoundException < Exception; end

  STYLE = {

Avatar Resizer

kedare (Mathieu Poussin) — Mon, 23 Apr 2007 17:13:46 GMT

I go on a lot of Bulletin Board, every has its own limits of size for the avatars, instead of the resize manually I created a script which does it for me with RMagick



#!/usr/bin/ruby

require "RMagick"

$SIZES = [80 , 100 , 110 , 128]



if !ARGV[0]

  puts "Usage: mk_avatars.rb SourceAvatarPath"

  exit

end



image = Magick::Image.read(ARGV[0]).first

$SIZES.each do |sz|

  puts "Generating Avatar : #{sz}"

  out = image.thumbnail(sz,sz)

  file = "out_#{sz}.#{image.format}"

  out.write(file)

end
