2.给现有PDF文档添加页眉页脚

【C#】

using Spire.Pdf;using Spire.Pdf.AutomaticFields;using Spire.Pdf.Graphics;using System;using System.Drawing;namespace PdfHeader{    class Program    {        static void Main(string[] args)        {            //加载一个测试文档            PdfDocument existingPdf = new PdfDocument();            existingPdf.LoadFromFile("Test.pdf");            //调用DrawHeader方法在现有文档添加页眉            DrawHeader(existingPdf);            //调用DrawFooter方法在现有文档添加页脚            DrawFooter(existingPdf);            //保存并打开文档            existingPdf.SaveToFile("output.pdf");            System.Diagnostics.Process.Start("output.pdf");        }        //在页面上方空白部位绘制页眉        static void DrawHeader(PdfDocument doc)        {            //获取页面大小            SizeF pageSize = doc.Pages[0].Size;            //声明x,y两个float型变量            float x = 90;            float y = 20;            for (int i = 0; i < doc.Pages.Count; i++)            {                //在每一页的指定位置绘制图片                PdfImage headerImage = PdfImage.FromFile("logo.png");                float width = headerImage.Width / 7;                float height = headerImage.Height / 7;                doc.Pages[i].Canvas.DrawImage(headerImage, x, y, width, height);                //在每一页的指定位置绘制横线                PdfPen pen = new PdfPen(PdfBrushes.Gray, 0.5f);                doc.Pages[i].Canvas.DrawLine(pen, x, y + height + 2, pageSize.Width - x, y + height + 2);            }        }        //在页面下方空白部位绘制页脚        static void DrawFooter(PdfDocument doc)        {            //获取页面大小            SizeF pageSize = doc.Pages[0].Size;            //声明x,y两个float型变量            float x = 90;            float y = pageSize.Height - 72;            for (int i = 0; i < doc.Pages.Count; i++)            {                //在每一页的指定位置绘制横线                PdfPen pen = new PdfPen(PdfBrushes.Gray, 0.5f);                doc.Pages[i].Canvas.DrawLine(pen, x, y, pageSize.Width - x, y);                //在每一页的指定位置绘制文字                y = y + 5;                PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("黑体", 10f, FontStyle.Bold), true);                PdfStringFormat format = new PdfStringFormat(PdfTextAlignment.Left);                String footerText = " Website\n https://g20.org/";                doc.Pages[i].Canvas.DrawString(footerText, font, PdfBrushes.Black, x, y, format);                                 //在每一页的指定位置当前页码和总页码                PdfPageNumberField number = new PdfPageNumberField();                PdfPageCountField count = new PdfPageCountField();                PdfCompositeField compositeField = new PdfCompositeField(font, PdfBrushes.Black, "{0}/{1}", number, count);                compositeField.StringFormat = new PdfStringFormat(PdfTextAlignment.Right, PdfVerticalAlignment.Top);                SizeF size = font.MeasureString(compositeField.Text);                compositeField.Bounds = new RectangleF(pageSize.Width - x - size.Width, y, size.Width, size.Height);                compositeField.Draw(doc.Pages[i].Canvas);            }        }    }}
