Re: [Matplotlib-users] Using Agg for my own purposes

[Graeme L. <gra...@gm...>]

  Thanks, this is enough to get me started.  You weren't kidding about
the "not really documented" part.  The Agg documentation is also
lacking.  One of my thesis advisor's favorite lines, "Use the source,
Luke", comes to mind.  It's only funny the first time you hear it.
  I'm using GTK, so I replaced the PIL show() business at the end of
the example with the following, and it works.  Maybe this will help
someone else.

import pygtk
pygtk.require('2.0')
import gtk

def area_expose_cb(area, event):
=09s =3D buffer.to_string()
=09gc =3D area.get_style().fg_gc[gtk.STATE_NORMAL]
=09area.window.draw_rgb_32_image(gc, 0, 0, width, height,
gtk.gdk.RGB_DITHER_NONE, s)

win =3D gtk.Window(gtk.WINDOW_TOPLEVEL)
win.set_title('Direct Agg drawing into GTK app')
win.connect("destroy", lambda w: gtk.main_quit())
area =3D gtk.DrawingArea()
area.set_size_request(width, height)
area.connect("expose-event", area_expose_cb)
win.add(area)
win.show_all()

gtk.main()
