缘起：

在抖音中看到有小盆友使用ps来实现照片拼接效果，顿生一个念头：是不是可以使用firemonkey技术来实现，浅浅地试了一下，居然成功了。

思路如下：

     1、使用multidevice窗体。

     2、使用Layout衬底，放置Rectangle作为画布载入照片，在它上面放置4个Rectangle并动态加载画框gif照片（注意画框当中要镂空）。

     3、使用cnwizard生成代码即可：

var
  Form1: TForm1;
  icount: Integer;

implementation

{$R *.fmx}

procedure TForm1.Action1Execute(Sender: TObject);
begin
  Self.CornerButton2.Visible := False;
  CornerButton2Click(Self);
end;

procedure TForm1.Action2Execute(Sender: TObject);
begin
  CornerButton1Click(self);
end;

procedure TForm1.CornerButton1Click(Sender: TObject);
var
  Rectangle1: TRectangle;
  Rectangle2: TRectangle;
  Rectangle3: TRectangle;
  Rectangle4: TRectangle;
  Rectangle5: TRectangle;

  ShadowEffect3: TShadowEffect;
  ShadowEffect4: TShadowEffect;
  ShadowEffect5: TShadowEffect;
