open IronPdfCreate a PDF from HTML with F#
Begin by opening the IronPDF library within your namespace using open. After that, create a ChromePdfRenderer object and pass an HTML string into its RenderHtmlAsPdf method. If you already have an HTML file ready, you can pass the file path string as a parameter to RenderHtmlFileAsPdf.
HTML String to PDF in F#
open IronPdf
let html = "<p>Hello World</p>"
// Initialize the PDF Renderer
let renderer = ChromePdfRenderer()
// Render HTML as PDF
let pdf = html |> renderer.RenderHtmlAsPdf
// Save the PDF document
pdf.SaveAs("document.pdf") |> ignoreHTML File to PDF in F#
open IronPdf
let htmlFilePath = "C:/designs/html/layout.html"
// Initialize the PDF Renderer
let renderer = ChromePdfRenderer()
// Render HTML file as PDF
let pdf = htmlFilePath |> renderer.RenderHtmlFileAsPdf
// Save the PDF document
pdf.SaveAs("document.pdf") |> ignoreAdvanced IronPDF F# Template
Here is a more advanced example of creating a function that will format and style a PDF from a URL based on some rules and procedures:
open IronPdf
let CreateCompanyStandardDocument (url : string) =
// Setup Render Options with desired settings
let renderOptions = ChromePdfRenderOptions(
CssMediaType = Rendering.PdfCssMediaType.Screen,
EnableJavaScript = true,
PrintHtmlBackgrounds = true,
InputEncoding = System.Text.Encoding.UTF8,
MarginTop = 10,
MarginBottom = 10,
MarginLeft = 10,
MarginRight = 10
)
// Create Header Template for the PDF
let companyStyleHeader = HtmlHeaderFooter()
companyStyleHeader.HtmlFragment <- "<img src='https://ironsoftware.com/img/svgs/ironsoftware-logo-black.svg'>"
companyStyleHeader.DrawDividerLine <- true
// Apply the header to the Render Options
renderOptions.HtmlHeader <- companyStyleHeader
// Initialize Renderer with customized options
let renderer = ChromePdfRenderer(RenderingOptions = renderOptions)
// Generate PDF from URL without additional styles
let htmlPdfWithoutStyle = url |> renderer.RenderUrlAsPdf
// Add the styled header to the PDF document
htmlPdfWithoutStyle.AddHtmlHeaders companyStyleHeader |> ignore
// Return the created PDF document
htmlPdfWithoutStyle
let IronPdfUrlToPdf (url : string) =
// Create a styled PDF document from the given URL
let pdf = url |> CreateCompanyStandardDocument
// Save the PDF document to the file system
pdf.SaveAs("document.pdf") |> ignore
// Set your IronPDF License Key
IronPdf.License.LicenseKey <- "YOUR_LICENSE_KEY_HERE"
// Example usage: Convert the given URL to a PDF document
