[reportlab-users] How to draw text in a non-rectangular area?

Actually I did join the list -- I just used a plussed version of my
Anyway, here is a test program that demonstrates the best I could come up
with off the top of my head (please excuse me, I'm not the most skilled
programmer, and I am a brand new python user). This still doesn't really
help with justifying text or anything like that. Has anyone else tried to
do what I'm trying to do? Is there a better way to accomplish this?
# File: point_in_frame_test.py
# Coordinates for an irregular frame, in inches
# Note: Must be clockwise coordinates!
frame = [( 1.8125, 3.5000 ),
( 6.6875, 3.5000 ),

( 5.6875, 1.8125 ),
( 2.8125, 1.8125 ),
( 1.8125, 2.8125 )]
points = [( 0.8125, 3.5000 ), # x=outside, y=top border (false)
( 2.8125, 2.8125 ), # x=inside, y=inside (true)
( 2.8125, 1.8125 ), # on bottom left corner (false)
( 7.6875, 0.8125 )] # x=outside, y=outside (false)
"""Returns the area for a given set of three points."""
(x0, y0), (x1, y1), (x2,y2) = pointset
area=(.5)*(x1*y2 - y1*x2 - x0*y2 + y0*x2 + x0*y1 - y0*x1)
def isInside(frame, point):
"""Returns true if the given frame contains the given point."""
for i in range(2, len(frame)+1):
pointset = frame[i-2:i]
a = areaOfTriangle(pointset)
if a >= 0:
for point in points:
if isInside(frame, point):
print "Yes, point ", point, " is inside frame."
print " No, point ", point, " is not inside frame."

We don't have anything to do this at present, you'd have
to 'roll your own' container.
Also, normally you have to join our users list first,
otherwise posts get held pending review.
