Description
This function searches for a given color specified by Color within a tolerance range specified by Tol inside of a given search area specified by xs, ys, xe, ye using a scan-line pattern. The search area is given as a set of upper-left (xs, ys) and lower-right (xe, ye) coordinates which are specified relative to the selected client window. The function returns the number of pixels it found, as a result of this 0 is returned when the color was not found. The active tolerance algorithm can be changed using the ColorToleranceSpeed function.
Example
var
w, h: Integer;
begin
GetClientDimensions(w, h);
WriteLn('Counted color ' + IntToStr(CountColorTolerance(4, 0, 0, w - 1, h - 1, 5)) + ' times');
end.
