添加HTML页眉和页脚

const {PdfDocument} = require("@ironsoftware/ironpdf");

(async () => {
    // Configure render options
    const renderOptions = {
        firstPageNumber: 1, // Use 2 if a cover page will be appended

        // Build a footer using html to style the text
        // mergeable fields are:
        // {page} {total-pages} {url} {date} {time} {html-title} & {pdf-title}
        htmlFooter: {
            maxHeight: 15, //millimeters
            htmlFragment: "<center><i>{page} of {total-pages}<i></center>",
            dividerLine: true,
        },

        // Build a header using an image asset
        htmlHeader: {
            maxHeight: 15, //millimeters
            htmlFragment: "<img src='logo.png'>",
        },

        // Use sufficient MarginBottom to ensure that the HtmlFooter does not overlap with the main PDF page content.
        margin: {
            top: 25, // Create 25mm space for the header
            bottom: 25, // Create 25mm space for the footer
        },
    };
})();

添加HTML页眉和页脚

配置渲染选项以在使用IronPDF进行PDF文档渲染时包含HTML页眉和页脚。IronPDF是Iron Software推出的库，允许进行高级PDF生成和操作。

通过分隔线和HTML片段定义页眉内容，并使用IronPDF灵活的PDF渲染工具指定页眉的最大高度。类似地，使用IronPDF提供的htmlHeader属性定义页脚内容。

请注意，页眉和页脚的高度不会自动检测，这意味着它们可能会与主要HTML内容重叠。自定义边距以确保页眉和页脚适当定位。

有关如何实现页眉、页脚或探索其他功能的更多详细信息，请访问IronPDF官方网站。
