Interpolation and image drawing

Question

In my little project I have a function that returns a list of points coordinates. Like this:

    points = [(x1, y1), (x2, y2),...]

When I draw it on image, I get points on image but I want continious line. How can I get it? And how to draw interpolated lines on an image?

Answer 1

To draw lines, do the following:

import Image
import ImageDraw

im = Image.new('RGB',(500,500),(255,255,255))
draw = ImageDraw.Draw(im)
draw.line(points, fill=(255,0,0))
del draw 
im.save('output.jpg')

Once you understand the above code you'll be able to use the answers in this question to draw antialiased lines.
