But now, I would like to get the bitmap or pixmap, the data itself to play
with it, with Bitmap, or anything else.

You can create your own bitmap or pixmap and draw in it as
appropriate, or you can get a Gtk::Gdk::Image from a drawable
and use the get_pixel/set_pixel on it, if you really want to get
dirty with low-level details. Note that this last is not for the faint
of heart.

My question is : How can I get the Bitmap, or pixmap data , and not only
Gtk::Gdk::Pixmap=HASH(0x8209708). How can I get what's inside ?

For those who are wondering why I'm doing that, I've a nice pixmap on my
gnome panel, and I would like to have a fancy perl_gtk applet on it. So I
want the applet to be transparent wheter than grey on most pixel possible.
I think I can do that with shape_combine_mask, but first I need to have a

A mask here is simply a Bitmap (that is a 1 bit depth Pixmap).
So, create such a pixmap, draw on it your shape and use it
as the mask. Or use one of the several other cfunctions that
greate a Gtk::Gdk::Bitmap...
