Definition
function FindColorCircle(out X, Y: Integer; const Color, CX, CY, R: Integer): Boolean;
Availability
SCAR Divi 3.00 > 3.34
Description
This function searches for a given color specified by Color inside of a given circular search area specified by the midpoint (CX, CY) and the radius r using a scan-line pattern.
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.
Example
var
w, h: Integer;
x, y: Integer;
begin
GetClientDimensions(w, h);
if FindColorCircle(x, y, 0, w div 2, h div 2, w div 4) then
WriteLn('Found color at ' + IntToStr(x) + ', ' + IntToStr(y));
end.
