Re: [pygtk] pygtk compiled with numpy for win32
Hello, Maybe you can use the gtk.gdk.pixbuf_new_from_data() function instead. Take a look at this module (som functions I prototyped for my Gscreendump program). http://www.futuredesktop.com/tmp/switch_desktop.py Look for get_window_icon_image function. Use struct.pack_into(...) to pack the data appropriately into a byte array. Ref: http://docs.python.org/dev/3.0/library/struct.html struct.pack_into(=, bytearr, offset, b1, b2, b3, b4) then call pixbuf = gtk.gdk.pixbuf_new_from_data(bytearr, gtk.gdk.COLORSPACE_RGB, True, 8, icon_width, icon_height, icon_width * 4) // Moma Antero Oslo Craig Warren wrote: Hi folks, I'm trying to use gtk.gdk.pixbuf_new_from_array to make a pixbuf from a numpy array and getting a runtime error pygtk was not compiled with Numeric Python support.

Re: [pygtk] pygtk compiled with numpy for win32
Thanks, I'm currently using gtk.gdk.pixbuf_new_from_data() after converting the numpy array using to_string. Unfortunately I'm updating largegtk.gdk.pixbuf_new_from_array would overcome this bottleneck. I'll try using struct.pack_into(..) and see if this is faster?
