How does PixelSearch work?

[Rexit]

Hey guys!

 

I was wondering how autoit pixelsearch actually works. Does it output the first pixel it finds in the area.. is there a way for it to say how many of those it has found and display every single one of them or not..

 

Thanks in advance

Well, the idea is that when you set the values for the rectangle to search, depending on the values you put in,

then the function will search in that direction. As explained in the help file.

Normally the left value is lower than the right, this means it starts to search from left to right, in order to invert this order of search, you have to invert the coordinates.

So yes, the function will say what was the first pixel found in the area, but it does so in a particular order and direction set by you.

As for getting how many were found, that would be a question of excluding the ones that were already flagged.

I didn't search for it, but im sure there are already examples of that around here.

As @careca said there is multiple examples on how you could do it.  But I tested performance on many of them, and I can tell you that GDI+ performs the best when searching for many pixels.  If you only search for 2-3 pixels, then PixelSearch would probably be faster.
