You might want to try again.  This is pretty much guaranteed to work.
The Figure.draw method in figure.py reads:

  if self.frameon: self.figurePatch.draw(renderer)

I don't see how the patch can be drawn if frameon is false...

This was the start of an attempt to get rid of the gtkagg extension
code and replace it with pure pygtk calls.  There is an equivalent
method for older version of pygtk.  For now, in _backend_gtkagg.py in
the _render_figure method, just uncomment

        #agg_to_gtk_drawable(pixmap, self.renderer._renderer, None)

and comment out


        buf = self.buffer_rgba(0,0)
        ren = self.get_renderer()
        w = int(ren.width)
        h = int(ren.height)
        pixbuf = gtk.gdk.pixbuf_new_from_data(
            buf, gtk.gdk.COLORSPACE_RGB,  True, 8, w, h, w*4)
        pixmap.draw_pixbuf(pixmap.new_gc(), pixbuf, 0, 0, 0, 0, w, h, gtk.gdk.RGB_DITHER_NONE, 0, 0)


Or upgrade your pygtk (2.4 or later, me thinks)

A challenge to the community! ;)

Run the current cursor.py example with the TkAgg backend. (blitting
should be on)
i.e.  python cursor.py -dTkAgg

Why does the blitting not update the entire axis?  Any help on this is
greatly appreciated.

Thanks,
     Charlie

Hi:

I just updated to 0.85 which appeared on sf today.  I'm getting this 
error using the gtk-agg backend on macos x:

Traceback (most recent call last):
  File 
"/sw/lib/python2.4/site-packages/matplotlib/backends/backend_gtk.py",

0.84 worked fine. Do I need a newer version of pygtk?

I tried that before. It gives a filled white frame without border line.
I checked that using skencil and pstoedit to convert into skencil's own format.
Btw. I'm using a smaller figure size than the default and the eps always
contains a small polygon with 4 nodes down at the left bottom of larger page
which is about DIN A4/US Letter which makes the bounding box unnecessary big.

    Christian> Any other ideas?

You want 

  fig = figure(frameon=False)

or for an existing fig

  fig.frameon = False

Indeed the frame line is not drawn in that case, but it is still beeing filled.
To prevent filling I tried:

f.figurePatch.fill = False
setp(f.figurePatch, facecolor='black', edgecolor='black', linewidth=0)

but now the frame line is back again - in white.

Any other ideas?

In the PostScript model (and thus also PDF), a linewidth of 0 means "1
pixel at the rendered resolution," not that the line is invisible.

Hmm, that's surprising.  Does the standard define what the default
initialization value for std::string should be.  Me thinks it would be
""; In any case, I made the change.  Can't hurt.

Try regenerating the SWIG headers on your local machine by installing
*the most recent* version of SWIG and then running

python makeswig.py

before trying to build.  This will regenerate the SWIG runtime.

Alternatively, you could try with mpl 0.85 which has a new version of
SWIG headers (built on a solaris box, coincidentally)

If your logo is a fixed size in pixels, you can also use figimage to
place an unscaled image directly onto the canvas.

A wiki entry on matplotlib images + PIL would be useful.

    Christian> figure(frameon=False) seems to have no effect.

The standard trick is to set the figure facecolor and edgecolor to be
the same.  For whatever reason, a linewidth of 0 is not handled
consistently across ps drivers.

setp(figurePatch, facecolor=somecolor, edgecolor=somecolor, linewidth=0)

should work.
