使用项目标记和编号，可以让文档的条理布局更清晰、更有层次，也更容易突出重点。在编纂文档的过程中，，我小我私家也对照偏爱项方针号来标注文章重点信息。在之前的文章中，介绍了如安在Word中来创建项方针号和编号列表，在本篇文章中，将介绍创建PDF项目标记列表和多级编号列表的要领。
借助工具：Free Spire.PDF for .NET
PS：dll可以直接在安置路径下的Bin文件夹中获取。
1.创建PDF标记列表
C
using System;
using System.Drawing;
using Spire.Pdf;
using Spire.Pdf.Graphics;
using Spire.Pdf.Lists;
namespace CreateList_PDF
{
class Program
{
static void Main(string[] args)
{
//创建一个PDF文档
PdfDocument doc = new PdfDocument();
//添加一页A4巨细的页面
PdfPageBase page = doc.Pages.Add(PdfPageSize.A4);
float y = 10;
//创建标题并设置格局，包孕字体、字号、颜色
PdfBrush brush1 = PdfBrushes.Black;
PdfTrueTypeFont font1 = new PdfTrueTypeFont(new Font("楷体", 18f, FontStyle.Regular), true);
PdfStringFormat format1 = new PdfStringFormat(PdfTextAlignment.Center);
page.Canvas.DrawString("Categories List（项目列表）", font1, brush1, page.Canvas.ClientSize.Width / 2, y, format1);
y = y + font1.MeasureString("Categories List（项目列表）", format1).Height;
y = y + 5;
//创建列表文字并设置格局
RectangleF rctg = new RectangleF(new PointF(0, 0), page.Canvas.ClientSize);
PdfLinearGradientBrush brush
= new PdfLinearGradientBrush(rctg, Color.SteelBlue, Color.Blue, PdfLinearGradientMode.Vertical);
PdfTrueTypeFont font2 = new PdfTrueTypeFont(new Font("宋体", 15f, FontStyle.Regular), true);
String formatted
= "Part 1 Listening（听力部分） \n Part 2 Speaking（白话部分） \n Part 3 Reading（阅读部分） \n Part 4 Writing（写作部分）"
+ "\n Part 5 Test（测试） 1 \n Part 6 Test（测试） 2 \n Part 7 Test Answers（测试答案）";
//创建PdfList 类东西，并设置列表及样式
PdfList list = new PdfList(formatted);
list.Font = font2;
list.Indent = 8;
list.TextIndent = 5;
list.Brush = brush;
PdfLayoutResult result = list.Draw(page, 0, y);
y = result.Bounds.Bottom;
//生存并打开文档
doc.SaveToFile("List.pdf");
System.Diagnostics.Process.Start("List.pdf");
}
}
}
测试功效：
VB.NET
Imports System
Imports System.Drawing
Imports Spire.Pdf
Imports Spire.Pdf.Graphics
Imports Spire.Pdf.Lists
Namespace CreateList_PDF
Class Program
Private Shared Sub Main(ByVal args As String())
Dim doc As PdfDocument = New PdfDocument()
Dim page As PdfPageBase = doc.Pages.Add(PdfPageSize.A4)
Dim y As Single = 10
Dim brush1 As PdfBrush = PdfBrushes.Black
Dim font1 As PdfTrueTypeFont = New PdfTrueTypeFont(New Font("楷体", 18F, FontStyle.Regular), True)
Dim format1 As PdfStringFormat = New PdfStringFormat(PdfTextAlignment.Center)
page.Canvas.DrawString("Categories List（项目列表）", font1, brush1, page.Canvas.ClientSize.Width / 2, y, format1)
y = y + font1.MeasureString("Categories List（项目列表）", format1).Height
y = y + 5
Dim rctg As RectangleF = New RectangleF(New PointF(0, 0), page.Canvas.ClientSize)
Dim brush As PdfLinearGradientBrush = New PdfLinearGradientBrush(rctg, Color.SteelBlue, Color.Blue, PdfLinearGradientMode.Vertical)
Dim font2 As PdfTrueTypeFont = New PdfTrueTypeFont(New Font("宋体", 15F, FontStyle.Regular), True)
Dim formatted As String = "Part 1 Listening（听力部分） " & vbLf & " Part 2 Speaking（白话部分） " & vbLf & " Part 3 Reading（阅读部分） " & vbLf & " Part 4 Writing（写作部分）" & vbLf & " Part 5 Test（测试） 1 " & vbLf & " Part 6 Test（测试） 2 " & vbLf & " Part 7 Test Answers（测试答案）"
Dim list As PdfList = New PdfList(formatted)
list.Font = font2
list.Indent = 8
list.TextIndent = 5
list.Brush = brush
Dim result As PdfLayoutResult = list.Draw(page, 0, y)
y = result.Bounds.Bottom
doc.SaveToFile("List.pdf")
System.Diagnostics.Process.Start("List.pdf")
End Sub
End Class
End Namespace
2.创建PDF多级编号列表
Spire.Pdf.dll撑持多种类型的编号类型
C
using Spire.Pdf;
using Spire.Pdf.Graphics;
using Spire.Pdf.Lists;
using System;
using System.Drawing;
namespace List2
{
class Program
{
static void Main(string[] args)
{
//新建PDF文档，并添加一页A4巨细的空白页面
PdfDocument doc = new PdfDocument();
PdfPageBase page = doc.Pages.Add(PdfPageSize.A4);
float y = 10;
//添加标题并设置文本和格局
PdfBrush brush1 = PdfBrushes.Black;
PdfTrueTypeFont font1 = new PdfTrueTypeFont(new Font("宋体", 18f, FontStyle.Regular), true);
PdfStringFormat format1 = new PdfStringFormat(PdfTextAlignment.Center);
page.Canvas.DrawString("目录一览", font1, brush1, page.Canvas.ClientSize.Width / 2, y, format1);
y = y + font1.MeasureString("目录一览", format1).Height;
y = y + 5;
//添加文本并设置字体
RectangleF rctg = new RectangleF(new PointF(0, 0), page.Canvas.ClientSize);
PdfLinearGradientBrush brush
= new PdfLinearGradientBrush(rctg, Color.DarkBlue, Color.Brown, PdfLinearGradientMode.Vertical);
PdfTrueTypeFont font2 = new PdfTrueTypeFont(new Font("宋体", 15f, FontStyle.Regular), true);
String formatted1 = "第一章 总 论";
String formatted2 = "第一节 经济法概述 ";
String formatted3 = "第二节 经济法主体 ";
String formatted4 = "第二章 公司法令制度";
//设置编号列表样式
PdfOrderedMarker marker1 = new PdfOrderedMarker(PdfNumberStyle.Numeric, new PdfFont(PdfFontFamily.Helvetica, 15f));
PdfOrderedMarker marker2 = new PdfOrderedMarker(PdfNumberStyle.LowerRoman, new PdfFont(PdfFontFamily.Helvetica, 12f));
//为第一级编号列表设置格局
PdfSortedList list1 = new PdfSortedList(font2);
list1.Indent = 0;
list1.TextIndent = 5;
list1.Brush = brush;
list1.Marker = marker1;
//为第二级编号列表设置格局
PdfSortedList list2 = new PdfSortedList(font2);
list2.Marker = marker2;
list2.Brush = brush;
list2.TextIndent = 10;
//应用编号列表格局到指定文本
PdfListItem item = list1.Items.Add(formatted1);
item.SubList = list2;
list2.Items.Add(formatted2);
list2.Items.Add(formatted3);
list1.Items.Add(formatted4);
//设置PDF文档结谈判位置
PdfTextLayout textLayout = new PdfTextLayout();
textLayout.Break = PdfLayoutBreakType.FitPage;
textLayout.Layout = PdfLayoutType.Paginate;
list1.Draw(page, new PointF(0, y), textLayout);
//生存文件
doc.SaveToFile("多级列表.pdf");
System.Diagnostics.Process.Start("多级列表.pdf");
}
}
}
