jsteng Posted June 14, 2014 Share Posted June 14, 2014 Hi, I am experimenting on _ScreenCapture_Capture at the moment and wants to clarify something: Return Value Returns a handle to an HBITMAP if $sFileName is empty. By Handle do you mean like a pointer to the actual data? New to AutoIT, so i am not familiar with the terms used/refered by AutoIT. If so, how can i access this data? or more importantly, i would like to do a checksum/hash on it, ie to represent that part of the screen into a shorter data that i can easily compare with. My intention is to do simple pattern recognition/comparison on a fix x1y1-x2y2 window. A full time OCR would be better but that is slow unfortunately. Considering i would like to do a checksum/hash, will PixelChecksum do the trick? ie, can Pixelchecksum be used to represent a particular area's pattern? according to the document, pixelchecksum is intended to check for change in the area but not pattern. what i want to do: I want to monitor a spot in the desktop 100x10 pixels (LABEL) in a fix spot. There are 8 possible patterns on that spot (ie 8 choices in the label) depending on what the value on the label, an input will have correspondingly diffent set of possible answers. i would therefore like the script to be able to answer this input field based on the pattern on this LABEL. currently i am doing an imagesearch by comparing the fix spot LABEL with 8 diffent png files. though it is working, itis not efficient because it can take at most 8 imagesearches to find a match. as it is, it is taking 0.1 seconds to perform imagesearch and 8 of that is 0.8 seconds, average 0.4 seconds. if somehow I can capture the area into a hash or string or integer, i can easily then do a SELECT CASE search which is extremely faster.

JohnOne Posted June 14, 2014 Share Posted June 14, 2014 PixelChecksum is good for that. AutoIt Absolute Beginners Require a serial Pause Script Video Tutorials by Morthawt ipify Monkey's are, like, natures humans. Link to comment Share on other sites More sharing options...

BrewManNH Posted June 14, 2014 Share Posted June 14, 2014 This sounds a lot like a captcha, is that what you're trying to code for? If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.Give a programmer the correct code and he can do his work for a day. Teach a programmer to debug and he can do his work for a lifetime - by Chirag GudeHow to ask questions the smart way! I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.
