# coding=gbk
import Image, ImageDraw
import ImageFont
im = Image.open("a.jpg")
# Creates an object that can be used to draw in the given image.
draw = ImageDraw.Draw(im)
# draw.line(xy, options) => Draws a line between the coordinates in the xy list.
# The coordinate list can be any sequence object containing either 2-tuples [ (x, y), ... ]
# or numeric values [ x, y, ... ].
# The fill option gives the color to use for the line.
draw.line((0, 0) + im.size, fill=128)
draw.line((0, im.size[1], im.size[0], 0), fill=128)
ttFont = ImageFont.truetype ("arial.ttf", 16)
draw.text ((10, 10), "Hello", fill=(255,0,0), font=None)
del draw
# write to stdout
im.save("b.jpg")
