Note that if you use Psyco this lookup trick isn't useful, but if the
Psyco isn't available it can improve performance a little:
append = BitmapList['lines'].append
I suggest to replace this code:
red, green, blue

That's a strong question...
Knowing OOP well is important, and it's often a good way to program,
etc. But... You may try to rewrite your code with functions only and

for line in bmp.bitmap_lines.lines:
for color in xrange(len(line.colors)):
canvas.create_line(x, y, x+1, y, fill="#%02x%02x%02x"
% (line.colors
