使用GDI +图形旋转打印内容

Question

我正在根据此Link创建designsurface。

我需要将文档打印到打印机。我使用以下代码。一切都印刷得很好。

private void pdPrintDocument_PrintPage(object sender, PrintPageEventArgs e)
        {

            SizeF sz = e.Graphics.VisibleClipBounds.Size;
            e.Graphics.TranslateTransform(sz.Width, sz.Height);



            e.Graphics.RotateTransform(180);
           //draw sample string
            e.Graphics.DrawString("Hello", new Font(FontFamily.GenericSerif, 12, FontStyle.Bold, GraphicsUnit.Pixel), Brushes.Blue, new RectangleF(50, 50, 100, 75), new StringFormat());
           //draw the objects from designsurface
            designSurfaceCtrl.DrawingObjects.PrintObjects(e.Graphics);


            e.Graphics.RotateTransform(-180);

            e.HasMorePages = false;


        designSurfaceCtrl.Invalidate();
    }

但是当试图将整个文档旋转到180时，只打印文本Hello。

在PrintObjects方法中调用的其他对象不打印。

其他方法：

  public void PrintObjects(Graphics g)
        {


     g.PageUnit = GraphicsUnit.Pixel;
                if (InnerList.Count > 0)
            {
                int i;
                ArrayList jk = new ArrayList();

            for (i = 0; i <= InnerList.Count - 1; i++)
            {
                jk.Add(InnerList[i]);
            }
            for (i = 0; i <= jk.Count - 1; i++)
            {
                var drawObj = (GraphicObject)jk[i];
                if (drawObj.IsPrintable)
                {
                    drawObj.Draw(g);
                }
            }

        }
    }  

对象绘制覆盖：

public override void Draw(Graphics g, bool withBackground = false)
        {
            var gContainer = g.BeginContainer();

            if (AutoSize)
            {
                SizeF mySize = g.MeasureString(Account1Text, MFont);
                Width = Convert.ToInt32(mySize.Width);
                Height = Convert.ToInt32(mySize.Height + 2);

                //while printing no need to print background color
                if (withBackground)
                {
                    g.FillRectangle(new SolidBrush(MBackColor), X, Y, Width, Height);

                }

                g.DrawString(Account1Text, MFont, new SolidBrush(MColor), X, Y);


            }
            else
            {
                RectangleF rect1 = new RectangleF(X, Y, Width, Height + 2);

                //while printing no need to print background color
                if (withBackground)
                {
                    g.FillRectangle(new SolidBrush(MBackColor), X, Y, Width, Height);

                }

                g.DrawString(Account1Text, MFont, new SolidBrush(MColor), rect1);


            }
            g.EndContainer(gContainer);
        }

我应该在哪里研究？
