3. 建立PDF文件

3.1. 使用IronPDF

IronPDF有多種方法可以建立PDF。讓我們來探討其中兩個重要的方法。

現有URL至PDF

IronPDF使得將任何URL轉換為PDF變得容易。以下程式碼有助於將URL轉換為PDF。

var Renderer = new IronPdf.ChromePdfRenderer();
// Render a PDF from an existing URL
using var Pdf = Renderer.RenderUrlAsPdf("https://ironpdf.com/");
// Save the PDF to a file
Pdf.SaveAs("url.pdf");

var Renderer = new IronPdf.ChromePdfRenderer();
// Render a PDF from an existing URL
using var Pdf = Renderer.RenderUrlAsPdf("https://ironpdf.com/");
// Save the PDF to a file
Pdf.SaveAs("url.pdf");

Dim Renderer = New IronPdf.ChromePdfRenderer()
' Render a PDF from an existing URL
Dim Pdf = Renderer.RenderUrlAsPdf("https://ironpdf.com/")
' Save the PDF to a file
Pdf.SaveAs("url.pdf")

Dim Renderer = New IronPdf.ChromePdfRenderer()
' Render a PDF from an existing URL
Dim Pdf = Renderer.RenderUrlAsPdf("https://ironpdf.com/")
' Save the PDF to a file
Pdf.SaveAs("url.pdf")

HTML輸入字串至PDF

下面的程式碼說明了如何從HTML字串渲染PDF文件。您可以使用HTML或將其與CSS、圖片和JavaScript結合使用。

var Renderer = new IronPdf.ChromePdfRenderer();
// Render a PDF from a simple HTML string
using var PDF = Renderer.RenderHtmlAsPdf("<h1>Html with CSS and Images</h1>");
PDF.SaveAs("pixel-perfect.pdf");

// Load external HTML assets like images, CSS, and JavaScript
// Set the optional BasePath as the file location to load assets from
using var AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='logo.png'><h1>Sample Text</h1>", @"C:\site\assets\");
AdvancedPDF.SaveAs("html-with-assets.pdf");

var Renderer = new IronPdf.ChromePdfRenderer();
// Render a PDF from a simple HTML string
using var PDF = Renderer.RenderHtmlAsPdf("<h1>Html with CSS and Images</h1>");
PDF.SaveAs("pixel-perfect.pdf");

// Load external HTML assets like images, CSS, and JavaScript
// Set the optional BasePath as the file location to load assets from
using var AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='logo.png'><h1>Sample Text</h1>", @"C:\site\assets\");
AdvancedPDF.SaveAs("html-with-assets.pdf");

Dim Renderer = New IronPdf.ChromePdfRenderer()
' Render a PDF from a simple HTML string
Dim PDF = Renderer.RenderHtmlAsPdf("<h1>Html with CSS and Images</h1>")
PDF.SaveAs("pixel-perfect.pdf")

' Load external HTML assets like images, CSS, and JavaScript
' Set the optional BasePath as the file location to load assets from
Dim AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='logo.png'><h1>Sample Text</h1>", "C:\site\assets\")
AdvancedPDF.SaveAs("html-with-assets.pdf")

Dim Renderer = New IronPdf.ChromePdfRenderer()
' Render a PDF from a simple HTML string
Dim PDF = Renderer.RenderHtmlAsPdf("<h1>Html with CSS and Images</h1>")
PDF.SaveAs("pixel-perfect.pdf")

' Load external HTML assets like images, CSS, and JavaScript
' Set the optional BasePath as the file location to load assets from
Dim AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='logo.png'><h1>Sample Text</h1>", "C:\site\assets\")
AdvancedPDF.SaveAs("html-with-assets.pdf")

輸出如下：

IronPDF 從URL和HTML CSS字串生成PDF

3.2. 使用Apitron PDF Kit

Apitron PDF不提供將URL或HTML轉換為PDF的方法。它允許將PDF轉換為HTML。不過，它也將XML文件轉換為PDF。使用的XML文件是：

<?xml version="1.0" encoding="utf-8"?>
<FlowDocument xmlns="Apitron.PDF.Kit.FlowLayout.v1">
  <Resources>
    <Image resourceId="logo" fileName="../../images/logo.png" />
  </Resources>
  <Styles>
    <Style selector="flowdocument">
      <Color value="Black" />
    </Style>
    <Style selector="grid">
      <InnerBorder thickness="1" />
      <InnerBorderColor value="Black" />
    </Style>
  </Styles>
  <Elements>
    <Image>
      <Properties>
        <Class value="logo" />
        <ResourceId value="logo" />
      </Properties>
    </Image>
    <TextBlock>
      <Properties>
        <Class value="header" />
        <Text value="Sample Interview Questions for Candidates" />
      </Properties>
    </TextBlock>
    <Br />
    <TextBlock>
      <Properties>
        <Class value="headerNote" />
        <Text value="To help facilitate the interview process, the Human Resources Department has compiled a list of questions that might be used during the phone and/or on-campus interviews. Some of the questions deal with the same content, but are phrased differently while other questions may not pertain to a specific discipline; however all of the questions are unbiased and appropriate to ask. We hope you'll find this helpful." />
      </Properties>
    </TextBlock>
  </Elements>
  <Properties>
    <Margin value="30,20,30,20" />
  </Properties>
</FlowDocument>

<?xml version="1.0" encoding="utf-8"?>
<FlowDocument xmlns="Apitron.PDF.Kit.FlowLayout.v1">
  <Resources>
    <Image resourceId="logo" fileName="../../images/logo.png" />
  </Resources>
  <Styles>
    <Style selector="flowdocument">
      <Color value="Black" />
    </Style>
    <Style selector="grid">
      <InnerBorder thickness="1" />
      <InnerBorderColor value="Black" />
    </Style>
  </Styles>
  <Elements>
    <Image>
      <Properties>
        <Class value="logo" />
        <ResourceId value="logo" />
      </Properties>
    </Image>
    <TextBlock>
      <Properties>
        <Class value="header" />
        <Text value="Sample Interview Questions for Candidates" />
      </Properties>
    </TextBlock>
    <Br />
    <TextBlock>
      <Properties>
        <Class value="headerNote" />
        <Text value="To help facilitate the interview process, the Human Resources Department has compiled a list of questions that might be used during the phone and/or on-campus interviews. Some of the questions deal with the same content, but are phrased differently while other questions may not pertain to a specific discipline; however all of the questions are unbiased and appropriate to ask. We hope you'll find this helpful." />
      </Properties>
    </TextBlock>
  </Elements>
  <Properties>
    <Margin value="30,20,30,20" />
  </Properties>
</FlowDocument>

XML

將此XML模板轉換為PDF的程式碼如下：

// Use Apitron's FlowDocument to convert XML to PDF
using (Stream stream = File.OpenRead("C:\PLACE YOUR EXACT PATH HERE\template.xml"), 
               outputStream = File.Create("fromTemplate.pdf"))
{
    ResourceManager resourceManager = new ResourceManager();
    FlowDocument doc = FlowDocument.LoadFromXml(stream, resourceManager);

    doc.Write(outputStream, resourceManager);
}

// Use Apitron's FlowDocument to convert XML to PDF
using (Stream stream = File.OpenRead("C:\PLACE YOUR EXACT PATH HERE\template.xml"), 
               outputStream = File.Create("fromTemplate.pdf"))
{
    ResourceManager resourceManager = new ResourceManager();
    FlowDocument doc = FlowDocument.LoadFromXml(stream, resourceManager);

    doc.Write(outputStream, resourceManager);
}

' Use Apitron's FlowDocument to convert XML to PDF
Using stream As Stream = File.OpenRead("C:\PLACE YOUR EXACT PATH HERE\template.xml"),
      outputStream As Stream = File.Create("fromTemplate.pdf")

    Dim resourceManager As New ResourceManager()
    Dim doc As FlowDocument = FlowDocument.LoadFromXml(stream, resourceManager)

    doc.Write(outputStream, resourceManager)
End Using

' Use Apitron's FlowDocument to convert XML to PDF
Using stream As Stream = File.OpenRead("C:\PLACE YOUR EXACT PATH HERE\template.xml"),
      outputStream As Stream = File.Create("fromTemplate.pdf")

    Dim resourceManager As New ResourceManager()
    Dim doc As FlowDocument = FlowDocument.LoadFromXml(stream, resourceManager)

    doc.Write(outputStream, resourceManager)
End Using

輸出如下：

Apitron PDF文件

如果比較IronPDF和Apitron的輸出，我們可以清楚地看到IronPDF使用HTML渲染建立了令人印象深刻的文件，甚至未縮放圖像大小。而Apitron僅在XML文件有註冊樣式時才能給出類似的輸出。

4. 向PDF文件新增頁眉和頁腳

4.1. 使用IronPDF

使用IronPDF新增頁眉和頁腳非常簡單。 IronPDF允許您新增頁碼和分頁符，附加封面頁、邊距等。

新增頁眉和頁腳的程式碼如下：

var Renderer = new ChromePdfRenderer();

// Add a header
Renderer.RenderingOptions.FirstPageNumber = 1; // Use 2 if a cover page will be appended
Renderer.RenderingOptions.TextHeader.DrawDividerLine = true;
Renderer.RenderingOptions.TextHeader.CenterText = "This is the header text";
Renderer.RenderingOptions.TextHeader.Font = IronPdf.Font.FontTypes.Helvetica;
Renderer.RenderingOptions.TextHeader.FontSize = 12;
Renderer.RenderingOptions.MarginTop = 25; // Create 25mm space for header

// Add a footer too
Renderer.RenderingOptions.TextFooter.DrawDividerLine = true;
Renderer.RenderingOptions.TextFooter.Font = IronPdf.Font.FontTypes.Arial;
Renderer.RenderingOptions.TextFooter.FontSize = 12;
Renderer.RenderingOptions.TextFooter.LeftText = "{date} {time}";
Renderer.RenderingOptions.TextFooter.RightText = "{page} of {total-pages}";
Renderer.RenderingOptions.MarginTop = 25; // Create 25mm space for footer

using var AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='logo.png'><h1>This is header and footer generated pdf file</h1>", @"C:\site\assets\");
AdvancedPDF.SaveAs("html-with-assets.pdf");

var Renderer = new ChromePdfRenderer();

// Add a header
Renderer.RenderingOptions.FirstPageNumber = 1; // Use 2 if a cover page will be appended
Renderer.RenderingOptions.TextHeader.DrawDividerLine = true;
Renderer.RenderingOptions.TextHeader.CenterText = "This is the header text";
Renderer.RenderingOptions.TextHeader.Font = IronPdf.Font.FontTypes.Helvetica;
Renderer.RenderingOptions.TextHeader.FontSize = 12;
Renderer.RenderingOptions.MarginTop = 25; // Create 25mm space for header

// Add a footer too
Renderer.RenderingOptions.TextFooter.DrawDividerLine = true;
Renderer.RenderingOptions.TextFooter.Font = IronPdf.Font.FontTypes.Arial;
Renderer.RenderingOptions.TextFooter.FontSize = 12;
Renderer.RenderingOptions.TextFooter.LeftText = "{date} {time}";
Renderer.RenderingOptions.TextFooter.RightText = "{page} of {total-pages}";
Renderer.RenderingOptions.MarginTop = 25; // Create 25mm space for footer

using var AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='logo.png'><h1>This is header and footer generated pdf file</h1>", @"C:\site\assets\");
AdvancedPDF.SaveAs("html-with-assets.pdf");

Dim Renderer = New ChromePdfRenderer()

' Add a header
Renderer.RenderingOptions.FirstPageNumber = 1 ' Use 2 if a cover page will be appended
Renderer.RenderingOptions.TextHeader.DrawDividerLine = True
Renderer.RenderingOptions.TextHeader.CenterText = "This is the header text"
Renderer.RenderingOptions.TextHeader.Font = IronPdf.Font.FontTypes.Helvetica
Renderer.RenderingOptions.TextHeader.FontSize = 12
Renderer.RenderingOptions.MarginTop = 25 ' Create 25mm space for header

' Add a footer too
Renderer.RenderingOptions.TextFooter.DrawDividerLine = True
Renderer.RenderingOptions.TextFooter.Font = IronPdf.Font.FontTypes.Arial
Renderer.RenderingOptions.TextFooter.FontSize = 12
Renderer.RenderingOptions.TextFooter.LeftText = "{date} {time}"
Renderer.RenderingOptions.TextFooter.RightText = "{page} of {total-pages}"
Renderer.RenderingOptions.MarginTop = 25 ' Create 25mm space for footer

Dim AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='logo.png'><h1>This is header and footer generated pdf file</h1>", "C:\site\assets\")
AdvancedPDF.SaveAs("html-with-assets.pdf")

Dim Renderer = New ChromePdfRenderer()

' Add a header
Renderer.RenderingOptions.FirstPageNumber = 1 ' Use 2 if a cover page will be appended
Renderer.RenderingOptions.TextHeader.DrawDividerLine = True
Renderer.RenderingOptions.TextHeader.CenterText = "This is the header text"
Renderer.RenderingOptions.TextHeader.Font = IronPdf.Font.FontTypes.Helvetica
Renderer.RenderingOptions.TextHeader.FontSize = 12
Renderer.RenderingOptions.MarginTop = 25 ' Create 25mm space for header

' Add a footer too
Renderer.RenderingOptions.TextFooter.DrawDividerLine = True
Renderer.RenderingOptions.TextFooter.Font = IronPdf.Font.FontTypes.Arial
Renderer.RenderingOptions.TextFooter.FontSize = 12
Renderer.RenderingOptions.TextFooter.LeftText = "{date} {time}"
Renderer.RenderingOptions.TextFooter.RightText = "{page} of {total-pages}"
Renderer.RenderingOptions.MarginTop = 25 ' Create 25mm space for footer

Dim AdvancedPDF = Renderer.RenderHtmlAsPdf("<img src='logo.png'><h1>This is header and footer generated pdf file</h1>", "C:\site\assets\")
AdvancedPDF.SaveAs("html-with-assets.pdf")

輸出如下：

IronPDF頁眉和頁腳

4.2. 使用Apitron PDF Kit

Apitron PDF Kit通過將以XML結构格式的内容轉換為PDF來建立PDF。在Apitron PDF Kit中，可以使用PageFooter屬性新增頁眉和頁腳。這方面的程式碼如下：

// Register document resources first
ResourceManager resourceManager = new ResourceManager();
resourceManager.RegisterResource(new Apitron.PDF.Kit.FixedLayout.Resources.XObjects.Image("logo", "../../data/logo.png"));

// Create the document
FlowDocument doc = new FlowDocument() { Margin = new Thickness(10) };

// Register styles
doc.StyleManager.RegisterStyle(".pageHeader", new Style() { Font = new Font(StandardFonts.TimesBold, 20) });
doc.StyleManager.RegisterStyle(".pageFooter", new Style() { Align = Align.Right });
doc.StyleManager.RegisterStyle("hr", new Style() { Height = 2, Margin = new Thickness(0, 5, 0, 5) });
doc.StyleManager.RegisterStyle(".content", new Style() { Align = Align.Left, Display = Display.InlineBlock });

// Fill the header section
doc.PageHeader.Class = "pageHeader";
doc.PageHeader.Add(new Image("logo") { Width = 100, Height = 50 });
doc.PageHeader.Add(new TextBlock("This document is intended for internal use only") { TextIndent = 20 });
doc.PageHeader.Add(new Hr());

// Fill the footer section
doc.PageFooter.Class = "pageFooter";
doc.PageFooter.Add(new Hr());
doc.PageFooter.Add(new TextBlock((ctx) => string.Format("Page {0} from&nbsp;", ctx.CurrentPage + 1)));
doc.PageFooter.Add(new PageCount(3) { Display = Display.Inline });

// Add pages
for (int i = 0; i < 2; ++i)
{
    doc.Add(new TextBlock("This is header and footer generation pdf file.") { Class = "content" });
    doc.Add(new PageBreak());
}

// Generate PDF
using (Stream stream = File.Create("out.pdf"))
{
    doc.Write(stream, resourceManager);
}

Process.Start("out.pdf");

// Register document resources first
ResourceManager resourceManager = new ResourceManager();
resourceManager.RegisterResource(new Apitron.PDF.Kit.FixedLayout.Resources.XObjects.Image("logo", "../../data/logo.png"));

// Create the document
FlowDocument doc = new FlowDocument() { Margin = new Thickness(10) };

// Register styles
doc.StyleManager.RegisterStyle(".pageHeader", new Style() { Font = new Font(StandardFonts.TimesBold, 20) });
doc.StyleManager.RegisterStyle(".pageFooter", new Style() { Align = Align.Right });
doc.StyleManager.RegisterStyle("hr", new Style() { Height = 2, Margin = new Thickness(0, 5, 0, 5) });
doc.StyleManager.RegisterStyle(".content", new Style() { Align = Align.Left, Display = Display.InlineBlock });

// Fill the header section
doc.PageHeader.Class = "pageHeader";
doc.PageHeader.Add(new Image("logo") { Width = 100, Height = 50 });
doc.PageHeader.Add(new TextBlock("This document is intended for internal use only") { TextIndent = 20 });
doc.PageHeader.Add(new Hr());

// Fill the footer section
doc.PageFooter.Class = "pageFooter";
doc.PageFooter.Add(new Hr());
doc.PageFooter.Add(new TextBlock((ctx) => string.Format("Page {0} from&nbsp;", ctx.CurrentPage + 1)));
doc.PageFooter.Add(new PageCount(3) { Display = Display.Inline });

// Add pages
for (int i = 0; i < 2; ++i)
{
    doc.Add(new TextBlock("This is header and footer generation pdf file.") { Class = "content" });
    doc.Add(new PageBreak());
}

// Generate PDF
using (Stream stream = File.Create("out.pdf"))
{
    doc.Write(stream, resourceManager);
}

Process.Start("out.pdf");

5. 數位簽名PDF

5.1. 使用IronPDF

最重要的PDF處理功能之一是能夠數位簽名PDF文件。 IronPDF提供了執行此操作所需的所有工具。

using IronPdf;

// Cryptographically sign an existing PDF in 1 line of code!
new IronPdf.Signing.PdfSignature("Iron.p12", "123456").SignPdfFile("any.pdf");

/***** Advanced example for more control *****/

// 1. Create a PDF
var Renderer = new IronPdf.ChromePdfRenderer();
var doc = Renderer.RenderHtmlAsPdf("<h1>Testing 2048 bit digital security</h1>");

// 2. Create a Signature.
// You may create a .pfx or .p12 PDF signing certificate using Adobe Acrobat Reader.

var signature = new IronPdf.Signing.PdfSignature("Iron.pfx", "123456");

// 3. Handwritten signature graphic
signature.LoadSignatureImageFromFile("handwriting.png");

// 4. Sign the PDF with the PdfSignature. Multiple signing certificates may be used
doc.SignPdfWithDigitalSignature(signature);

// 5. The PDF is not signed until saved to file, stream or byte array.
doc.SaveAs("signed.pdf");

兩個程式庫的輸出基本相同。您可以清晰地看到IronPDF在操作PDF內容方面更簡單更方便。輸出的PDF上帶有證書和簽名。

將Bootstrap 5與IronPDF用於組合庫

IronPDF的Chrome V8渲染引擎完全支持現代Bootstrap 5組件，使您能夠生成具有專業組合庫的視覺驚人的PDF文件。此範例展示了網格佈局、懸停效果、漸變疊加和類別徽章——這些功能用傳統PDF程式庫如Apitron PDF SDK難以實現。

此程式碼生成了一個專業的PDF組合，具有響應式網格佈局、視覺類別徽章、漸變疊加和懸停效果。 Chrome渲染引擎保留了所有Bootstrap樣式、CSS網格佈局和自定義CSS屬性——這些是傳統PDF程式庫難以復制的功能。

與Apitron PDF SDK的主要優勢：

原生支持Bootstrap 5而無需轉換
CSS網格和Flexbox佈局完美渲染
漸變背景和現代CSS效果
更簡單的程式碼與更高質量的輸出

關於Bootstrap PDF生成的完整指導，可參見HTML to PDF Bootstrap指南。

IronPDF授權

Apitron PDF Kit價格和授權

目前正在使用兩種授權方案 - 現代和舊版。如果您已擁有授權，那麼舊版授權方案將在授權到期之前對您仍然有效。之後，您需要聯繫客戶支援以轉換方案。現代授權方案僅適用於新客戶。

在現代方案下，有三個授權級別：

評估 - 三個月的評估期內使用功能完善的產品。只需從NuGet下載包，然後開始開發。
社區 - 在非商業项目中免費使用功能齊全的產品。需要獲得批准。
商業 - 任何上述未描述的使用情形。價格根據使用模式而定。

結論

IronPDF程式庫從HTML、JS、CSS、JPG、PNG、GIF和SVG等文件格式建立像素完美的PDF。 Chromium引擎有助於渲染HTML文件或URL，以給出完美的PDF作為輸出。

Apitron讓您使用固定佈局API建立PDF，該API實施已達到100%的PDF規範相容。作為一種類似於HTML和CSS的樣式驅動內容生成方法，此固定佈局API使您能夠在幾分鐘內建立令人驚豔的報告、賬單、目錄等。它還支持建立XML模板。

Apitron PDF的授權價格未在其網站上發布。您需聯繫支援並根據您的使用情況獲得報價。另一方面，IronPDF在其網站上顯示了非常清楚的授權包。這使得IronPDF在競爭中脫穎而出，並讓使用者可以根據自己的需求做出明智的選擇。

使用IronPDF，您可以比使用Apitron PDF更容易工作PDF文件。 IronPDF允許使用者在處理挑戰性的PDF工作時寫下更少的程式碼行。 IronPDF提供多種方法來從多種文件型別生成PDF，而Apitron僅能將XML文件轉換為PDF文件。在IronPDF中無需新增任何技術選項即可達到完美的輸出，與Apitron相比。

所有Iron Software客戶都可以以兩個產品的價格購買公司全部五個產品。試用免費，30天的IronPDF試用版來測試其所有功能。購買Iron Software產品的全套在IronSoftware.com。
