Pixmaps are server-side objects. the client (your app) has no access to
them.

you will want to use a GdkPixbuf instead, which is a client-side object
that has pixel values that you can actually read.

it, like GdkPixmap, is a GdkDrawable, and so can be used for all the
same things that a GdkPixmap can.
