PixelSearch

[Jeanpierre92]

I got a problem with:

PixelSearch ( left, top, right, bottom, color [, shade-variation [, step [, hwnd]]] )

shade-variation [optional] A number between 0 and 255 to indicate the allowed number of shades of variation of the red, green, and blue components of the colour. Default is 0 (exact match).

I dont understand the explaination . If you got a color like: Red: 100 Blue: 20 Green: 250 and you set the Shade variation to 10, and it finds a color like this: R:80 B:15 G:100 will the script take that color as found? or must it be: R:80+-10, B:15 +-10, G:100+-10? Or just only one must be in range of +-10 shades?

Thanks, Jeanpierre

Jeanpierre92,

I have no idea what AutoIt actually does internally, but logically the shade must apply to all 3 colour elements. If it only applied to one, then the colours which would fire a positive response from the function could be completely different:

R:100 B:20 G:250 Shade:10

R:255 B:15 G:0    ; Almost pure red
R:0   B:15 G:235  ; Almost pure blue

which would rather defeat the object of the command.

So I would suggest your "R:80+-10, B:15+-10, G:100+-10" suggestion is the correct one.

aah thanks for the very logic explain

Now I see its logic that all the 3 colors must be + or - the shade variation.
