Forum: Ruby-Gnome 2 Simple image viewer questions

Hi.

I'd like to create a simple image viewer.
At the moment it is enough to have one button
and a widget that displays predefined images.
I used glade-3 to create a skeleton.

It works but when watching the memory consumption using 'top',
I noticed that the script allocates about 20MB more memory
each time I click the button and the next image is loaded.
Do you have an idea how this can be avoided?

I chose Gdk::Pixbuf because I think it's the only way to
change the resolution of the image loaded.

Here's a code snippet of what I tried:

class ImgselectorGlade
  include GetText

  def initialize(path_or_data, root = nil, domain = nil, localedir = 
nil, flag = GladeXML::FILE)
    GetText.bindtextdomain(domain, localedir, nil, "UTF-8")
    @glade = GladeXML.new(path_or_data, root, domain, localedir, flag) 
{|handler| method(handler)}

    # Images to display
    @images = "test.jpg", "test2.jpg"

    # Count of images
    @count = @images.length
    @counter = 0

    # Get the main window and show it
    @window = @glade.get_widget("mainWindow")
    @window.show

    # Get the image widget
    @image_widget = @glade.get_widget("imageWindow")

    on_buttonNext_clicked
  end

  def on_buttonNext_clicked
    if (@counter += 1) >= @count
      @counter = 0
    end

    image = Gdk::Pixbuf.new(@images[@counter], 1024, 768)
    @image_widget.set(image)
  end

  def on_quit
    Gtk.main_quit
  end

end

Hi,

the garbage collector doesn't work that good for things like big data
chunks like images. Simply put a GC.start after displaying a new image.
