I found a little helper function that does what you want (and more) import cairo import pango import pangocairo def draw_text(surface, context, text, font="sans 14", position=None, color=None, box_width=None, alignment=pango.ALIGN_CENTER, line_spacing=None, letter_spacing=None, extra_kerning=None): if color is None: color = (0.0, 0.0, 0.0) context.set_source_rgb(*color) pc = pangocairo.CairoContext(context) layout = pc.create_layout() layout.set_text(text) layout.set_font_description(pango.FontDescription(font)) if box_width: layout.set_width(box_width) layout.set_alignment(alignment) if line_spacing: layout.set_spacing(spacing) alist = pango.AttrList() if letter_spacing: alist.insert(pango.AttrLetterSpacing(letter_spacing, 0, len (text))) if extra_kerning: for pos, kern in extra_kerning.iteritems(): alist.insert(pango.AttrLetterSpacing(kern, pos, pos +1)) layout.set_attributes(alist) if position is None: width, height = surface.get_width(), surface.get_height() w, h = layout.get_pixel_size() position = (width/2.0 - w/2.0, height/2.0 - h/2.0) context.move_to(*position) pc.show_layout(layout) And example usage: surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, width, height) context = cairo.Context(surface) draw_text(surface, context, 'Hello world!', font="sans 52", color=(.25,.28,.33), letter_spacing=-6000, extra_kerning={0:-9000, 1:-1000, 6:6000, 7:-15000, 8:5000, 9:-7000}) surface.write_to_png("hello.png") -- Ivan -- http://mail.python.org/mailman/listinfo/python-list
