Biblioteca PDF em F# (Tutorial completo)

Instale através do Gerenciador de Pacotes NuGet

No Visual Studio, clique com o botão direito do mouse no explorador de soluções do seu projeto e selecione "Gerenciar Pacotes NuGet...". A partir daí, basta pesquisar por IronPDF e instalar a versão mais recente. Clique em OK em todas as caixas de diálogo que aparecerem. Isso funcionará em qualquer projeto .NET.

Instale através do Console do Gerenciador de Pacotes NuGet.

Você também pode optar por adicionar o IronPDF através do console do gerenciador de pacotes, o que pode ser feito com este comando:

Install-Package IronPdf

Instale diretamente no arquivo .fsproj.

Outra opção é colar o seguinte ItemGroup no seu arquivo .fsproj:

<ItemGroup>
  <PackageReference Include="IronPdf" Version="*" />
</ItemGroup>

<ItemGroup>
  <PackageReference Include="IronPdf" Version="*" />
</ItemGroup>

Instalar via DLL

Alternatively, the IronPDF DLL can be downloaded and manually installed to the project or GAC from https://ironpdf.com/packages/IronPdf.zip

Lembre-se de adicionar esta declaração ao início de qualquer arquivo de classe .fs usando o IronPDF:

open IronPdf

open IronPdf

String HTML para PDF em 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") |> ignore

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") |> ignore

Converter arquivo HTML para PDF em 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") |> ignore

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") |> ignore

Modelo avançado do IronPDF F

Aqui está um exemplo mais avançado de criação de uma função que formatará e estilizará um PDF a partir de uma URL com base em algumas regras e procedimentos:

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
IronPdfUrlToPdf "https://ironpdf.com/"

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
IronPdfUrlToPdf "https://ironpdf.com/"
