Note however that modifying the pixel data of some GdkPixbufs will cause a segfault (ones that are backed by a const string, such as the stock icons). Pixbufs you create yourself are safe to modify though.

I am trying to figure out a simple way of converting a Numeric array to
a gtk.gdk.Pixbuf without depending on PIL.
Assuming that you have a (n,m,3) or (n,m,4) shape 'b' type array of RGB or RGBA values called 'data', you would do this:Added as FAQ 8.3, thanks:
w,h = data.shape[:2]
hasalpha = shape.shape[3] == 4
p = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, hasalpha, 8, w, h)
p.pixel_array[:] = data

Take care,
The PyGTK reference at http://www.moeraki.com/pygtkreference/pygtk2reference/class-gdkpixbuf.html says Attributes
"pixel_array" Read A numeric ...
So according to the reference pixel_array is a read only attribute. Is
the reference in error?
