Definition
function FindColorTolerance(var x, y: Integer; Color, xs, ys, xe, ye, Tol: Integer): Boolean;
Availability
SCAR Divi 3.00 > Current
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 false if the color was not found, if it was it returns true and the coordinates of the found color in (x, y). The search will stop after the first color was found. The active tolerance algorithm can be changed using the ColorToleranceSpeed function.
Example
var
w, h: Integer;
x, y: Integer;
begin
GetClientDimensions(w, h);
if FindColorTolerance(x, y, 4, 0, 0, w - 1, h - 1, 5) then
WriteLn('Found color at ' + IntToStr(x) + ', ' + IntToStr(y));
end.
