关于FastReport 读取数据库中的图片问题

Question

我看到很多人说可以将FastReport中的Picture控件里的BlodType设置成btJPG，可是我怎么也找不到BlodType属性，请问是什么原因。

Answer 1

以前写的代码．用的fastReport2.6 .参考一下吧：｛方法是：先将数据库中的用内存流读出,然后通过bmp 传递给报表．笨方法，现在也懒的改．｝
 　　if is_include_picture then
      begin
        bmp:=TBitmap.Create;
        tempStream:= TMemoryStream.Create;
        qry:=TADOQuery.Create(nil);         
        try
          qry.Connection:= DM.ADOConnection1;
          qry.close;
          qry.SQL.Clear;
          qry.SQL.Add('select * from tb_Patient_Graphic_INF where V_BRBM=:id1 order by v_lx' ) ;
          qry.Parameters.ParamByName('id1').Value:= BRID;
          qry.Open;
          if qry.RecordCount>0 then
          begin
            j:=1;
            qry.First;
            while (not qry.Eof) and (j<i) and  (pictureCount>0) do
            begin
              tempStream.Clear;
              TBlobField(qry.FieldByName('picture')).SaveToStream(tempStream);
              tempStream.Position:=0;
              bmp.LoadFromStream(tempStream);
              try
                FrView:= FrmPrintSetup.frReport1.Pages[0].findobject('picture'+inttostr(pictureCount)) ;
                if frview is TfrPictureView then
                  (FrView as TfrPictureView).Picture.Assign(bmp);
              except
              end;
              qry.Next;
              pictureCount:= pictureCount-1;
              Inc(j);
            end;
          end;        finally
          bmp.Free;
          tempStream.Free;
          qry.Free;
        end;
      end;
