into the<BR>>ImageGrab function.<BR>>I also did something cool, which is :<BR>> self.prevscr = self.currscr<BR>> self.currscr = ImageGrab.grab().resize((800,600))<BR>><BR>> diff = ImageChops.difference(self.prevscr,self.currscr)<BR>><BR>>Obviously you need a currscr before you start, which I declared during<BR>>the initialization of the class.<BR>>The cool part of this is that the ImageChops difference will return<BR>>black pixels in any area of the screen that hasn't changed.<BR>>so you can just send the changed parts over the network (if you have a<BR>>good algorithm to discard the unchanged portions).<BR>>Would be much faster than sending the whole screen every frame, obviously.<BR>>Not CPU-faster,
but network-faster.<BR>><BR>><BR>>------------------------------<BR>><BR>>Message: 3<BR>>Date: Fri, 3 Nov 2006 10:51:14 +0000<BR>>From: "Asrarahmed Kadri" <ajkadri@googlemail.com><BR>>Subject: [Tutor] Checking the format of IP address...<BR>>To: pythontutor <tutor@python.org><BR>>Message-ID:<BR>> <b4e894c70611030251h278becb2n166c439ac335f65b@mail.gmail.com><BR>>Content-Type: text/plain; charset="iso-8859-1"<BR>><BR>>Hi Folks,<BR>><BR>>I want to implement a simple program that verifies the IP provided by the<BR>>user is in the right format or not.<BR>><BR>>How to go about it..?<BR>>Any suggestions..<BR>><BR>>TIA.<BR>>Regards,<BR>>Asrarahmed<BR>><BR>><BR>>--<BR>>To HIM you shall return.<BR>>-------------- next part --------------<BR>>An HTML attachment was scrubbed...<BR>>URL:
