If you compile pygtk with Numeric support (and recent versions of the
pygtk win32 binary have numeric support built in), you can use pixel
arrays. In this example X us a MxNx4 (RGBA) pixel array
# fill your array X
X.shape = cols, rows, 4
pb=gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB,
has_alpha=1, bits_per_sample=8,
width=rows, height=cols)
# earlier versions of pygtk had pixel_array attribute, newer
# versions have the method get_pixels_array
try: pa = pb.get_pixels_array()
except AttributeError: pa = pb.pixel_array
pa[:,:,:] = X
gc = gdkDrawable.new_gc()
pb.render_to_drawable(gdkDrawable, gc, 0, 0,
int(x), int(self.height-y), rows, cols,
gdk.RGB_DITHER_NONE, 0, 0)
For 24 bit images you can just set the alpha channel to a constant
value.
