[reportlab-users] Is the graphics package slow?
Mon, 29 Mar 2004 16:15:13 -0500 (EST)
I'm currently considering reportlab to generate nice looking png
graphics to be displayed on dynamic web pages (using Webware). A typical
graphic is a scatter plot containing around 1000 data points. A short
test with reportlab (included below) seems to indicate that the generation
time for such graphic is around 1 second (PIII-1.3GHz), which is several
times slower than my current solution (biggles).
I'd like to know if I'm doing something obviously wrong in my code and
if any of you see a way to accelerate the process?
Thanks in advance,
from reportlab.graphics.shapes import *
from reportlab.graphics import renderPM
from random import random
data = 
for i in range (1000):
data.append ((random (), random ()))
def Scatter (fn):
d = Drawing (400, 400)
for p in data:
x = 400 * p
y = 400 * p
d.add (Circle (x, y, 2.2))
renderPM.drawToFile (d, fn, 'PNG')
for i in range (10):
