Subject: TkPhotoImage :data=>buf



does anyone know if this is simply a limitation of the gif formatted images?

irb(main):001:0> TkPhotoImage.new :file=>'images/Back.gif'                  
=> #<TkPhotoImage:0xb73290ec @type="photo", @path="i00006">

irb(main):002:0> (data=IO.read 'images/Back.gif').size
=> 985

irb(main):003:0> TkPhotoImage.new :data=>data             
RuntimeError: couldn't recognize image data
        from /dmsp/reference/lib/ruby/1.8/tk.rb:1623:in `__invoke'
        from /dmsp/reference/lib/ruby/1.8/tk.rb:1623:in `_invoke'
        from /dmsp/reference/lib/ruby/1.8/tk.rb:1027:in `tk_call'
        from /dmsp/reference/lib/ruby/1.8/tkcanvas.rb:883:in `initialize'
        from /dmsp/reference/lib/ruby/1.8/tkcanvas.rb:926:in `initialize'
        from (irb):11:in `new'
        from (irb):11
        from :0

am i limited to bitmaps for this or should other types of images be able to be
loaded this way?

what i'm trying to do is something like

....

  back_img = TkPhotoImage.new :data=>back_gif

  BEGIN {
        back_gif = '2158asdfanajk350w9ae8asdf....'
  }

....

in otherwords i want to inline all my icon images in the script.  i can do this
by inlining them, writing out a tempfile, and using that tempfile - but would
like to avoid the extra step...

any suggestions welcome - i'm terrible with tk and have two days to whip out
this gui...
