如何在PDF文档中添加书签或大纲？

GrabzIt可以使用PDF的内置大纲工具自动将书签添加到PDF文档。

为此，请指定包括轮廓参数，如下所示。然后，将通过分析网页的HTML中的H2和H3元素来自动创建轮廓，以使用这些元素的文本作为书签名称来生成书签，此外，H3元素将自动嵌套在书签列表中的H2项目下。

GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
PDFOptions options = new PDFOptions();
options.IncludeOutline = true;
grabzIt.URLToPDF("http://www.spacex.com", options);
grabzIt.Save("http://www.mywebsite.com/Home/Handler");

GrabzItClient grabzIt = new GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
PDFOptions options = new PDFOptions();
options.setIncludeOutline(true);
grabzIt.URLToPDF("http://www.spacex.com", options);
grabzIt.Save("http://www.mywebsite.com/handler");

<script src="https://cdn.jsdelivr.net/npm/@grabzit/js@3.3.7/grabzit.min.js"></script>
<script>
GrabzIt("Sign in to view your Application Key").ConvertURL("http://www.spacex.com", 
{"format": "pdf", "download": 1, "includeoutline": 1}).Create();
</script>

var grabzit = require('grabzit');

var client = new grabzit("Sign in to view your Application Key", "Sign in to view your Application Secret");
var options = {"includeOutline":true};
client.url_to_pdf("http://www.spacex.com", options);
client.save("http://www.example.com/handler", function (error, id){
    if (error != null){
        throw error;
    }
});

$grabzIt = GrabzItClient->new("Sign in to view your Application Key", "Sign in to view your Application Secret");
$options = GrabzItPDFOptions->new();
$options->includeOutline(1);
$grabzIt->URLToPDF("http://www.spacex.com", $options);
$grabzIt->Save("http://www.mywebsite.com/handler.pl");

$grabzIt = new \GrabzIt\GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret");
$options = new \GrabzIt\GrabzItPDFOptions();
$options->setIncludeOutline(true);
$grabzIt->URLToPDF("http://www.spacex.com", $options);
$grabzIt->Save("http://www.mywebsite.com/handler.php");

grabzIt = GrabzItClient.GrabzItClient("Sign in to view your Application Key", "Sign in to view your Application Secret")
options = GrabzItPDFOptions.GrabzItPDFOptions()
options.includeOutline = true
grabzIt.URLToPDF("http://www.spacex.com", options)
grabzIt.Save("http://www.mywebsite.com/handler.py")

grabzIt = GrabzIt::Client.new("Sign in to view your Application Key", "Sign in to view your Application Secret")
options = GrabzIt::PDFOptions.new()
options.includeOutline = true
grabzIt.url_to_pdf("http://www.spacex.com", options)
grabzIt.save("http://www.mywebsite.com/handler/index")

自定义书签和大纲

可以通过更改将要转换为PDF的HTML来定制书签。可以通过将H2书签添加到任何元素 GrabzItBookmarkH2 CSS类，类似地，可以通过将H3书签分配给元素来将其添加到元素 GrabzItBookmarkH3 CSS类。如果您想将HTML元素排除在书签之外，则可以分配 GrabzItBookmarkExclude 元素的类。下面的HTML中显示了使用这些特殊CSS类自定义书签的示例。

<html>
	<body>
		<h2 class="GrabzItBookmarkExclude">My Article</h2>
		<p>Ignorant branched humanity led now marianne too strongly entrance.</p>
		<span class="GrabzItBookmarkH2">Start here</span>
		<p>Rose to shew bore no ye of paid rent form.</p>
		<span class="GrabzItBookmarkH3">Then read this</span>
		<p>She which are maids boy sense her shade.</p>
	</body>
</html>
