F# PDF 函式庫（完整教學）

透過 NuGet 套件管理員安裝

在 Visual Studio 中，請在專案解決方案資源管理器上按右鍵，然後選取"管理 NuGet 套件..."。 接著只需搜尋 IronPDF 並安裝最新版本即可。 點擊任何彈出的對話方塊中的"確定"。此方法適用於任何 .NET 專案。

透過 NuGet 套件管理員控制台安裝

您亦可透過套件管理員主控台安裝 IronPDF，執行方式如下：

Install-Package IronPdf

直接安裝至 .fsproj 檔案

另一種做法是將以下 ItemGroup 內容貼入您的 .fsproj 檔案中：

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

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

透過 DLL 安裝

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

請記得在使用 IronPDF 的任何 .fs 類別檔案頂端加入以下陳述：

open IronPdf

open IronPdf

F# 中的 HTML 字串轉 PDF

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

使用 F# 將 HTML 檔案轉換為 PDF

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

進階 IronPDF F# 範本

以下是一個更進階的範例，展示如何建立一個函式，根據特定規則與流程，從網址取得 PDF 檔案並進行格式化與樣式設定：

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/"
