Description
This function returns the color at a given set of coordinates (X, Y) relative to the client window. The function returns -1 if the coordinates are outside of the client's boundaries.
Example
var
w, h: Integer;
x, y: Integer;
col: Integer;
begin
GetClientDimensions(w, h);
x := Random(w);
y := Random(h);
col := GetColor(x, y);
WriteLn('Color at (' + IntToStr(x) + ', ' + IntToStr(y) + ') is ' + IntToStr(col));
end.
