PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. The ImageDraw module provide simple 2D graphics for Image objects. You can use this module to create new images, annotate or retouch existing images, and to generate graphics on the fly for web use.
ImageDraw.Draw.line() Draws a line between the coordinates in the xy list.
Syntax: PIL.ImageDraw.Draw.line(xy, fill=None, width=0)
Parameters:
xy – Sequence of either 2-tuples like [(x, y), (x, y), …] or numeric values like [x, y, x, y, …].
fill – Color to use for the line.
width –The line width, in pixels. Note that line joins are not handled well, so wide polylines will not look good.Returns: An Image object in ellipse shape.
     # importing image object from PILimport mathfrom PIL import Image, ImageDraw  w, h = 220, 190shape = [(40, 40), (w - 10, h - 10)]  # creating new Image objectimg = Image.new("RGB", (w, h))  # create line imageimg1 = ImageDraw.Draw(img)  img1.line(shape, fill ="none", width = 0)img.show() |
Another Example: Here we use different colour for filling.
     # importing image object from PILimport mathfrom PIL import Image, ImageDraw  w, h = 220, 190shape = [(40, 40), (w - 10, h - 10)]  # creating new Image objectimg = Image.new("RGB", (w, h))  # create line imageimg1 = ImageDraw.Draw(img)  img1.line(shape, fill ="red", width = 0)img.show() |
