FYI, there is an updated version of that routine, which I'll post
here. Not an answer to your question, I know...
def draw_text_rotated(self, x=50, y=100):

Draw the text rotated 90 degrees
"""
gc = self.drawable.new_gc()
inkRect, logicalRect = self.layout.get_pixel_extents()
rect = inkRect
l, b, w, h = rect
# save the background
imageBack = self.drawable.get_image(x, y, w, h)
imageVert = self.drawable.get_image(x, y, h, w)
# transform the vertical image, write it onto the renderer,
# and draw the layout onto it
imageFlip = gtk.gdk.Image(type=gtk.gdk.IMAGE_NORMAL,
visual=self.drawable.get_visual(),
width=w, height=h)
if imageFlip is None or imageBack is None or imageVert is None:
print >> sys.stderr, "Could not renderer vertical text", s
return
imageFlip.set_colormap(self.drawable.get_colormap())
for i in range(w):
for j in range(h):
imageFlip.put_pixel(i, j, imageVert.get_pixel(j,w-i-1) )
self.drawable.draw_image(gc, imageFlip, 0, 0, x, y, w, h)
self.drawable.draw_layout(gc, x, y-b, self.layout)
# now get that image and flip it vertical
imageIn = self.drawable.get_image(x, y, w, h)
imageOut = gtk.gdk.Image(type=gtk.gdk.IMAGE_NORMAL,
visual=self.drawable.get_visual(),
width=h, height=w)
imageOut.set_colormap(self.drawable.get_colormap())
for i in range(w):
for j in range(h):
imageOut.put_pixel(j, i, imageIn.get_pixel(w-i-1,j) )
# draw the old background and the flipped text
self.drawable.draw_image(gc, imageBack, 0, 0, x, y, w, h)
self.drawable.draw_image(gc, imageOut, 0, 0, x, y, h, w)
return True
