Subject: Ruby GTK: problems with GdkImlib

Hi:

Trying the sample jpg image viewing program below I get the
following error:

./gtk.rb p4130011.jpg
./gtk.rb:24: uninitialized constant GdkImlib (NameError)

Is there a mistake in the docs, or has something changed?

Thanks

Jim


#!/usr/local/bin/ruby

require 'gtk'

#
# Ruby/Gtk + Imlib : view demo
#

if(ARGV.size != 1)
  print $0, " filename\n"
  exit
end
filename = ARGV.shift

window = Gtk::Window.new(Gtk::WINDOW_TOPLEVEL)
window.set_title(filename)
window.signal_connect('destroy'){ exit }
window.signal_connect('delete_event'){ exit }

vbox = Gtk::VBox.new(false, 0)
window.add(vbox)
vbox.show

im = GdkImlib::Image.new(filename)      # <---- Error occurs here
im.render(im.rgb_width, im.rgb_height)
pixd, maskd = im.get_pixmap
pixmap = Gtk::Pixmap.new(pixd, maskd)
pixmap.show
vbox.pack_start(pixmap, true, true, 0)

window.show
Gtk.main
