# image.py - Let's make an image!
# I downloaded Python Image Library (PIL) 1.1.6
#   from pythonware.com
# Documentation on it:
# http://www.pythonware.com/library/pil/handbook/index.htm
# When I installed it, the library of PIL files went in a new
#   directory inside C:\Python26 
# page 479 of book tells us how to add something to search path.

import sys

# Add PIL to our search path if it's not already there.
# To check, you can print sys.path - it's just a list.
PIL_path = "C:\\Python26\\lib\\site-packages\\PIL"
if PIL_path not in sys.path:
    sys.path.append(PIL_path)
           
import Image                    # allows us to create image
import ImageDraw                # more fancy stuff

# Basic image concepts are given in the "concepts" section of
# the pythonware documentation.  Also check out Image docs.
# http://www.pythonware.com/library/pil/handbook/concepts.htm
# http://www.pythonware.com/library/pil/handbook/image.htm
# Note that these functions require us to use 'tuples'
#   which are like lists except they can't be changed.

image = Image.new("RGB", (100,100))

# This will put a blue square in the middle:
##for x in range(40, 60):
##    for y in range(40, 60):
##        image.putpixel((x,y),(0,0,255))

# Vertical stripes
for x in range(0,100):
    for y in range(0,100):
        if (x / 20) % 2 == 0:
            image.putpixel((x,y),(0,0,255))
        else:
            image.putpixel((x,y),(255,0,0))            

# output
image.save("myimage.jpg")
