如何在C# .NET中翻转/旋转PrintDocument？

using System;
using System.Drawing;
using System.Drawing.Printing;

public class PrintExample
{
    private static PrintDocument printDocument = new PrintDocument();

    public static void Main()
    {
        printDocument.PrintPage += new PrintPageEventHandler(PrintPageHandler);
        printDocument.Print();
    }

    private static void PrintPageHandler(object sender, PrintPageEventArgs e)
    {
        // 获取要打印的内容
        string content = "Hello, World!";

        // 创建字体和画刷
        Font font = new Font("Arial", 12);
        SolidBrush brush = new SolidBrush(Color.Black);

        // 获取页面的宽度和高度
        int pageWidth = e.PageBounds.Width;
        int pageHeight = e.PageBounds.Height;

        // 创建一个Graphics对象，并设置其Transform属性进行翻转/旋转操作
        Graphics graphics = e.Graphics;
        graphics.TranslateTransform(pageWidth / 2, pageHeight / 2);
        graphics.RotateTransform(180); // 旋转180度

        // 绘制内容
        graphics.DrawString(content, font, brush, -pageWidth / 2, -pageHeight / 2);

        // 释放资源
        font.Dispose();
        brush.Dispose();
    }
}
