Hello.
I'm still struggling with displaying a PNG image on a gtk.DrawingArea. I
designed a glade interface that is basically a toplevel window with an hbox
in it. I then add() a gtk.DrawingArea in the hbox.
I'm trying to display the image this way:
fichier =
"/home/fab/tex/courante/TES/partie1/equations_et_inequations_du_second_degre.png"
self.imageOriginelle = gtk.gdk.pixbuf_new_from_file(fichier)
self.imageReduite = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, False, 8, 500,
700)
self.imageOriginelle.scale(self.imageReduite, 0, 0, 500, 700, 0, 0,
self.imageOriginelle.get_width()/500.0,
self.imageOriginelle.get_height()/700.0,
gtk.gdk.INTERP_HYPER)
I do this because I need to rescale the image so that it fits in my
interface. The 500 and 700 values are arbitrary and for tests purposes only.
I then try to display it:
self.GC = gtk.gdk.GC(self.zoneDeDessin.window)
self.zoneDeDessin.window.draw_pixbuf(self.GC, self.imageReduite, 0, 0, 0, 0)
where self.zoneDeDessin is the gtk.DrawingArea object I add()ed to the hbox.
I can see a white rectangle, but no image in it. What did I miss?
Thanks!
