I accidentally stumbled across the Turtle Graphics module (turtle.py)
the other day and have been having some fun with it.
Now I'm wondering if there is a way to build into a script the saving
of each window just before it is cleared. For example, here are a
couple that I've saved by screen capture:
<http://www.rcblue.com/Misc/RandomTriangles .jpg>
<http://www.rcblue.com/Misc/RandomTriangles 2.jpg>
They were produced by this script:
=============== =============== =============== ============
# randomTriangles .py
import turtle as T
from random import *
def twoRndN(low=0, high=1):
"""
generate two random floats x, y in the range [low, high) such that x <= y
"""
x, y = uniform(low, high), uniform(low, high)
if x <= y:
return x, y
else:
return y, x
T.setup(width=1 000, height=700, startx=0, starty=0)
T.title("Random Triangles with random R,G,B")
colorRange = "all"
if colorRange == "random":
lowR, highR = twoRndN()
lowG, highG = twoRndN()
lowB, highB = twoRndN()
count = 0
for n in range(300):
wdth = randrange(0,7,3 )
T.width(wdth)
T.speed("fastes t")
if colorRange == "dark":
R = uniform(.1, .5)
G = uniform(.1, .5)
B = uniform(.1, .5)
elif colorRange == "pastel":
R = uniform(.5, .9)
G = uniform(.5, .9)
B = uniform(.5, .9)
elif colorRange == "all":
R = uniform(0, 1)
G = uniform(0, 1)
B = uniform(0, 1)
# set RGB for one color of your choice
elif colorRange == "manual":
R = .45
G = .2
B = .2
elif colorRange == "random":
R = uniform(lowR, highR)
G = uniform(lowG, highG)
B = uniform(lowB, highB)
T.color(R,G,B)
T.begin_fill()
# 2 connected lines will fill as a triangle
for x in range(2):
coord = (randint(-500,500), randint(-350,350))
T.goto(coord)
T.end_fill()
count += 1
if count 5:
clr = randint(0,5)
if clr == 0:
T.clear()
count = 0
T.done()
=============== =============== =============== =
(The docs for Turtle graphics for Tk are at
<http://www.python.org/doc/2.5/lib/module-turtle.html>)
But how could I have saved them "automatically" ?
The script as shown will clear (T.clear() -- the 3rd line from the
bottom) the window after producing 6 to maybe 15 superimposed
triangles, so clearing will take place maybe 30 times. How can I save
as images each of the 30 windows just before they are cleared?
Thanks,

Turtle module uses Tk canvas element to draw graphics ('_canvas'
attribute). I've written module, that exports canvas graphics to SVG
file: http://wmula.republika.pl/proj/canvas2svg/ -- it may be useful
for you.

I afraid I'm totally unfamiliar with SVG. Would it be possible for
you or someone else on the list to show how to use your module to
export the simple product of this simple script to an SVG file?

For example Opera 9 and Firefox 1.5+ are able to view SVG files;
there is a free plugin for IrfanView.

Ha. I had tried it with Firefox 2 already, but I stupidly changed the
extension to HTM first. I'll also get the IrfanView plugin.
Thanks for all the help, and especially for your canvasvg.py module.
