import time

from ctypes import *
# Load up the Win32 APIs we need to use.
class RECT(Structure):
_fields_ = [

('top', c_ulong),
('right', c_ulong),
('bottom', c_ulong)
]
# time.sleep(2)
GetForegroundWindow = windll.user32.GetForegroundWindow
GetWindowRect = windll.user32.GetWindowRect
# Sleep for 2 seconds - click the window you want to grab.
#time.sleep(2)
# Grab the foreground window's screen rectangle.
rect = RECT()
foreground_window = GetForegroundWindow()
GetWindowRect(foreground_window, byref(rect))
image = ImageGrab.grab((rect.left, rect.top, rect.right, rect.bottom))
# Save the screenshot as a BMP.
time.sleep(2)
image.save("c:\python_codes\screenshot.bmp")
# Get the pixel 10 pixels along the top of the foreground window - this
# will be a piece of the window border.
# print time.time()
start = time.time()
pixels = image.getdata()
for x in xrange(0, 500):
for y in xrange(0, 500):
rgb = pixels[500 * x + y]
# print pixels[500 * 2 + 400]
print ( time.time() - start )
# PIL returns colours as RGB values packed into a triple:
#print "RGB(%d, %d, %d)" % (rgb[0], rgb[1], rgb[2]) # This prints RGB(0,
74, 216) on my XP machine
getdata() returns a flattened list, [n]
but i am not sure how to access it.
when I want to get rgb from a window of 100,200,
get data starts from 0 (0~99, 0~199)
the point of x,y = 2, 1
do I put in
pixel[100] ?
it's actually not the case @_@
what should I put in ?
