Description

This function searches for a given color specified by Color within a tolerance range specified by Tol 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. If the given search area is invalid (XS > XE or YS > YE), an exception is thrown.

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 instance of the color was found.

The active tolerance algorithm can be changed using the ColorToleranceSpeed function.

Example

var
  W, H: Integer;
  X, Y: Integer;
 
begin
  GetBoxSize(GetClient.ImageArea, W, H);
  if FindColorTol(X, Y, 0, 0, 0, W - 1, H - 1, 5) then
    WriteLn('Found color at ' + IntToStr(X) + ', ' + IntToStr(Y));
end.
