Backtrack FloodFill algoritm

[sk.Silvia]

hi there, iam trying to make a flood fill alghoritm (i created one using backtracking),the alghoritm is good, but the problem is that it stacks overflow by large inputs (what can i do ) i have 2048MB of Ram why i can use only a few kb for programmes...how can i tell delphi that it should use stack up to maximum?

Delphi-Quellcode:

 procedure TCore.SpillDraw(iX,iY:integer);
 var top_ln,bottom_ln,Mode:integer;
     replace_Char:string;

    procedure BacktrackFill(x,y:integer;fill_char,repl_char:char);
        begin
        if not(Edit.Cells[x,y]=fill_char) and (Edit.Cells[x,y]=repl_char) and (x<=Edit.ColCount) and (x>=0) and (y<=Edit.RowCount) and (y>=0) then
            begin
            //showmessage('test');
            Edit.Cells[x,y]:=fill_char;
            BacktrackFill(x,y,fill_char,repl_char);
            BacktrackFill(x-1,y,fill_char,repl_char);
            BacktrackFill(x+1,y,fill_char,repl_char);
            BacktrackFill(x,y-1,fill_char,repl_char);
            BacktrackFill(x,y+1,fill_char,repl_char);
            end;    
        end;

    begin
    
    if (Edit.MouseCoord(ix,iy).X>=0) and (Edit.MouseCoord(ix,iy).X<=Edit.ColCount) and (Edit.MouseCoord(ix,iy).Y>=0) and (Edit.MouseCoord(ix,iy).Y<=Edit.RowCount) then
        begin
        replace_Char:=Edit.Cells[Edit.MouseCoord(ix,iy).X,Edit.MouseCoord(ix,iy).Y];
        BacktrackFill(Edit.MouseCoord(ix,iy).X,Edit.MouseCoord(ix,iy).Y,SelectedChar,replace_Char[1]);
        end;
    end;
