Pixel detection with game guard

[vitor]

Hi

I play a game that I cannot use the function Pixelsearch to get the pixel color of the screen.

Its a game guard protection.

So I have to take a screenshot (using Dllcall) and open the bitmap file to analyze it.

The problem is that it takes TOO long using the library provided by eviltoaster

(http://www.autoitscript.com/forum/index.php?showtopic=27362&hl=bitmap)

It takes more than 30min to open a screenshot of size 1024x768.

Anyone has another library that reads BMP faster ?

Or a direct call from a DLL.

Or any ideias....

Thanks

30min to open a pic? Efficient LOL

Wait... Take a screenshot using a DllCall.

Why not make a screenshot of the pixel you want, and open that? That would take like 200ms in total. :|

Im taking screenshot with DLLCall.

The problem is that I dunno where the pixel is, so I must search it in all the picture image.

It would be interesting to know how gameguard is blocking the testing of pixel color. Maybe it is device context specific or even specific just to the pixel getter routine your using. So if you used a DC for the desktop window it might work? Or a bitmap capturing routine that only grabs 1 pixel?

These games using "RootKits" to block API calls are just nuts IMO...

I cannot grab 1 pixel because I dunno where that pixel is, so I must search the entire picture for a certain color.

Im using DllCall to get the screenshoot and save to a bmp file, and its working fine and fast.

The problem is to open it and look inside 1024x768 pixels.

I think I need a DLL function that do that faster, but it seems many people are looking for it and dont find.
