I ran this:
import time
import ImageGrab # Part of PIL
from ctypes import *
# Load up the Win32 APIs we need to use.
class RECT(Structure):
_fields_ = [
('left', c_ulong),
('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.
#image.save("c:\ee\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()
x = 0
y = 0
while x < 400:
while y < 20:
rgb = image.getpixel((10, 0))
y = y + 1
y = 0
x = x + 1
print time.time()
# 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
What that does is to take a screen shot and then pixelgetcolor() over 8000
(x,y) points
for me it clocked at 0.08 seconds and I am trying cut it down to maybe 0.04
any hints on performance increase?
