F# PDF Library (Full Tutorial)

通过 NuGet 包管理器安装

在 Visual Studio 中，右键单击您的项目解决方案资源管理器并选择“管理 NuGet 包...”。 从那里简单地搜索 IronPDF 并安装最新版本。 点击确定处理任何出现的对话框。这将在任何 .NET 项目中工作。

通过 NuGet 包管理器安装 Console

您也可以选择通过包管理器控制台添加 IronPDF，可以通过以下命令完成：

Install-Package IronPdf

直接在 .fsproj 中安装

另一种选择是将以下 ItemGroup 粘贴到您的 .fsproj 文件中：

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

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

通过 DLL 安装

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

请记得在任何使用 IronPDF 的.fs类文件顶部添加此声明：

open IronPdf

open IronPdf

HTML 字符串到 PDF 在 F# 中

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

HTML 文件到 PDF 在 F# 中

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

高级 IronPDF F# 模板

这里是一个更高级的示例，展示了如何创建一个函数，格式化和样式化 PDF，并根据某些规则和程序从一个 URL生成PDF：

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 = 0.39,
        MarginBottom = 0.38,
        MarginLeft = 0.39,
        MarginRight = 0.38
    )

    // 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 = 0.39,
        MarginBottom = 0.38,
        MarginLeft = 0.39,
        MarginRight = 0.38
    )

    // 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/"
