提取lazarus资源

Question

我创建了一个文件.Lrs并导入到程序中，它可以工作，但我如何从程序中提取资源并将其解压缩到我的PC上的某个位置？代码如下：

unit Unit1; 

{$mode objfpc}{$H+}

interface

uses
  Classes, SysUtils, FileUtil, Forms, LResources, Controls, Graphics, Dialogs, ExtCtrls;

type

  { TForm1 }

  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { private declarations }
  public
    { public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.lfm}

{ TForm1 }

procedure TForm1.FormCreate(Sender: TObject);
begin

end;

initialization
{$I resource.lrs}

end.

谢谢!

您可以使用属于LResources单元的TLazarusResourceStream类

尝试此示例

var
  Stream: TLazarusResourceStream;
begin
  Stream := nil;
  try
    //load the lazarus resource  
    Stream := TLazarusResourceStream.Create('image', nil);
    //save to a file
    Stream.SaveToFile('C:\Foo\image.png');
   finally
     Stream.Free;
   end;
end;
