RM报表的打印偏移

自己摸索一下

  RMReport1.SaveReportOptions.AutoLoadSaveSetting := True;
  RMReport1.SaveReportOptions.UseRegistry := False;
  RMReport1.SaveReportOptions.IniFileName := 'S:\rm.ini';//和每个报表文件一一对应

//下面这行FileName 一定要加，而且在LoadFromFile  前面
//原因是，程序运行，首次执行LoadFromFile，其调用LoadFromStream, 在LoadFromStream的最后部分会调用  FSaveReportOptions.LoadReportSetting(Self, '', False);
这时FFileName的值是'Untitled'。
而LoadFromFile  中在调用LoadFromStream(lStream);后才会设置 文件名。FileName := aFileName;

所以，必须 在 LoadFromFile  前 先设置FileName值。

RMReport1.FileName := 'd:\mydoc\桌面\测试背景图片.rmf';

  RMReport1.LoadFromFile('d:\mydoc\桌面\测试背景图片.rmf');

    RMReport1.ShowReport;
或者
RMReport1.PrintReport;

这样无论是先预览 再点击工具栏的打印按钮

还是 直接打印 ，最后的打印对话框上，都会显示 过去调试的 打印偏移值。

要把 模版导出到 其他电脑，或者 相同电脑的其他文件夹 内容使用。
只要复制2个文件，*.rm 和 *.ini

楼：    这个我看过源码,PrepareReport会将PrintOffset归零的.
如果你不动手改rm源码,可以在
 reportObj.PrepareReport;
  //放在这里才有效
  setoffset;
  reportObj.PrintPreparedReport

procedure TRMReport.OnTimerPrepareReportEvent(Sender: TObject);
begin
  FTimer.Enabled := False;
  while FCurPreview = nil do
    Application.ProcessMessages;

  PrepareReport;//这里，好像是线程准备报表
end;

procedure TRMReport.ShowReport;//
var
  lSaveThreadFlag: Boolean;
//  tmp: DWORD;
begin
  if FBusy then Exit;

  if FTimer = nil then
  begin
    FTimer := TTimer.Create(nil);
    with FTimer do
    begin
      Enabled := False;
      Interval := ;
      OnTimer := OnTimerPrepareReportEvent;//
    end;
  end;

  procedure _RestoreReport;
  var
    i: Integer;
    lSaveErrorFlag: Boolean;
