从HTML字符串生成PDF

为了从HTML字符串转换为PDF，我们可以使用RenderHtmlAsPdf方法迅速将HTML字符串转化为完美的PDF。

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// Create a PDF from a HTML string using C#
var pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>");

// Export to a file or Stream
pdf.SaveAs("output.pdf");

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// Create a PDF from a HTML string using C#
var pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>");

// Export to a file or Stream
pdf.SaveAs("output.pdf");

Imports IronPdf

' Instantiate Renderer
Private renderer = New ChromePdfRenderer()

' Create a PDF from a HTML string using C#
Private pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>")

' Export to a file or Stream
pdf.SaveAs("output.pdf")

Imports IronPdf

' Instantiate Renderer
Private renderer = New ChromePdfRenderer()

' Create a PDF from a HTML string using C#
Private pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>")

' Export to a file or Stream

将RTF转换为PDF

要将RTF文件转换为PDF，我们调用RenderRtfFileAsPdf方法，以RTF文件为输入。

using IronPdf;

// Instantiate Renderer
ChromePdfRenderer renderer = new ChromePdfRenderer();

// Render from RTF file
PdfDocument pdf = renderer.RenderRtfFileAsPdf("sample.rtf");

// Save the PDF
pdf.SaveAs("pdfFromRtfFile.pdf");

将XML转换为PDF

虽然将XML转换为PDF相当具有挑战性，但IronPDF仍能迎接挑战，并帮助在几步内将XML转换为PDF。我们从XLST模板开始，然后通过XLST转换将XML转为HTML再到PDF。这里提供了一个简化的代码片段以帮助您开始。

// XSLT template that defines the transformation from XML to HTML
string xslt = @"<?xml version='1.0' encoding='UTF-8'?>
<xsl:stylesheet version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>

除了将各种格式转换为PDF之外，IronPDF还支持将PDF转换为HTML的反操作。下面是一个快速的代码片段来演示这一功能。

using IronPdf;
using System;

PdfDocument pdf = PdfDocument.FromFile("sample.pdf");

// Convert PDF to HTML string
string html = pdf.ToHtmlString();
Console.WriteLine(html);

// Convert PDF to HTML file
pdf.SaveAsHtml("myHtml.html");

using IronPdf;
using System;

PdfDocument pdf = PdfDocument.FromFile("sample.pdf");

// Convert PDF to HTML string
string html = pdf.ToHtmlString();
Console.WriteLine(html);

// Convert PDF to HTML file
pdf.SaveAsHtml("myHtml.html");

Imports IronPdf
Imports System

Dim pdf As PdfDocument = PdfDocument.FromFile("sample.pdf")

' Convert PDF to HTML string
Dim html As String = pdf.ToHtmlString()
Console.WriteLine(html)

' Convert PDF to HTML file
pdf.SaveAsHtml("myHtml.html")

Imports IronPdf
Imports System

Dim pdf As PdfDocument = PdfDocument.FromFile("sample.pdf")

' Convert PDF to HTML string
Dim html As String = pdf.ToHtmlString()
Console.WriteLine(html)

' Convert PDF to HTML file
pdf.SaveAsHtml("myHtml.html")

// The library will convert Markdown syntax into equivalent HTML before rendering it as a PDF.
PdfDocument pdf = renderer.RenderMarkdownStringAsPdf(md);

// Save the generated PDF to a file named "renderingOptions.pdf."
pdf.SaveAs("renderingOptions.pdf");

using IronPdf;

优化您的PDF布局

添加目录

用IronPDF创建一个动态目录，帮助读者轻松导航您的文档。 IronPDF自动处理内容的目录，并通过h2等标题添加超链接。除此之外，您还可以使用HTML和CSS样式自定义目录的样式。

using IronPdf;

// Instantiate Renderer
ChromePdfRenderer renderer = new ChromePdfRenderer();

// Configure render options
renderer.RenderingOptions = new ChromePdfRenderOptions
{
    // Enable table of content feature
    TableOfContents = TableOfContentsTypes.WithPageNumbers,
};

PdfDocument pdf = renderer.RenderHtmlFileAsPdf("tableOfContent.html");

pdf.SaveAs("tableOfContents.pdf");

using IronPdf;

ChromePdfRenderer renderer = new ChromePdfRenderer();

// Configure render options
renderer.RenderingOptions = new ChromePdfRenderOptions
{
    // Enable table of content feature
    TableOfContents = TableOfContentsTypes.WithPageNumbers,
};

PdfDocument pdf = renderer.RenderHtmlFileAsPdf("tableOfContent.html");

pdf.SaveAs("tableOfContents.pdf");

Imports IronPdf

' Instantiate Renderer
Private renderer As New ChromePdfRenderer()

' Configure render options
renderer.RenderingOptions = New ChromePdfRenderOptions With {.TableOfContents = TableOfContentsTypes.WithPageNumbers}

Dim pdf As PdfDocument = renderer.RenderHtmlFileAsPdf("tableOfContent.html")
