Availability

Description
This function searches for a given color specified by Color 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 all found instances of the color in the TPointArray Points. The search will stop after the first color was found.
Example
var
w, h: Integer;
TPA: TPointArray;
begin
GetClientDimensions(w, h);
if FindColors(TPA, 0, 0, 0, w - 1, h - 1) then
WriteLn('Found color ' + IntToStr(Length(TPA)) + ' times');
end.
