// Set HTML header content using HtmlHeaderFooter.
renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter
{
    // HTML fragment to add a header at the top of every page in the PDF.
    HtmlFragment = "<h1>Header Content</h1>"
};

// Set a custom paper size for the PDF in millimeters (width and height).
renderer.RenderingOptions.SetCustomPaperSizeinMilimeters(150, 150);

// Set the top margin to zero to start the content from the very top of the page.
renderer.RenderingOptions.MarginTop = 0;

// Define a Markdown string that will be rendered as a PDF.
// Markdown text allows basic formatting like bold and italic styles.
string md = "This is some **bold** and *italic* text.";

// Render the Markdown string to a PDF document.
// 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;

// Instantiate a ChromePdfRenderer object, which uses a headless version of the Chrome browser

適合紙張和縮放

需要幫助決定如何根據指定紙張尺寸調整內容的尺寸嗎？IronPDF可透過UseChromeDefault為您解決這一問題，它模仿了Google Chrome的列印預覽如何縮放內容以適應頁面。

using IronPdf;

ChromePdfRenderer renderer = new ChromePdfRenderer();

// Chrome default rendering
renderer.RenderingOptions.PaperFit.UseChromeDefaultRendering();

// Render web URL to PDF
PdfDocument pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Main_Page");

pdf.SaveAs("chromeDefault.pdf");

using IronPdf;

ChromePdfRenderer renderer = new ChromePdfRenderer();

// Chrome default rendering
renderer.RenderingOptions.PaperFit.UseChromeDefaultRendering();

// Render web URL to PDF
PdfDocument pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Main_Page");

pdf.SaveAs("chromeDefault.pdf");

Imports IronPdf

Private renderer As New ChromePdfRenderer()

' Chrome default rendering
renderer.RenderingOptions.PaperFit.UseChromeDefaultRendering()

' Render web URL to PDF
Dim pdf As PdfDocument = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Main_Page")

pdf.SaveAs("chromeDefault.pdf")

Imports IronPdf

Private renderer As New ChromePdfRenderer()

' Chrome default rendering
renderer.RenderingOptions.PaperFit.UseChromeDefaultRendering()

' Render web URL to PDF
Dim pdf As PdfDocument = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/Main_Page")
