Cómo utilizar las opciones de renderizado en IronPDF con C

using IronPdf;

// Instantiate a ChromePdfRenderer object, which uses a headless version of the Chrome browser
// to render HTML/CSS as a PDF document.
ChromePdfRenderer renderer = new ChromePdfRenderer();

// Configure rendering options
// Enable printing of HTML backgrounds to ensure all styles are visible.
renderer.RenderingOptions.PrintHtmlBackgrounds = true;

// 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."
