Answer 1

创建一个TJPEGImage, 读入后再转化为BMP：代码如下：procedure TSeleteImageFrm.Button3Click(Sender: TObject);
var FileName:string;
    JPG:TJPEGImage;
    Bmp: TBitmap;
begin
  Panel1.BringToFront;
  OpenPictureDialog1.InitialDir:=ImagePath;
  OpenPictureDialog1.Filter:='打开图片文件[*.JPG]|*.JPG';
  if OpenPictureDialog1.Execute then
  begin
    FileName:=OpenPictureDialog1.FileName;
    JPG:=TJPEGImage.Create;
    Bmp:=TBitmap.Create;
    try
      JPG.LoadFromFile(FileName);
      BMP.Assign(JPG);
      Image1.Picture.Assign(BMP);
      Image2.Picture.Assign(BMP);
      ChangeImageSize;
    finally;
      JPG.Free;
      Bmp.Free;
    end;
  end;
end;
