嘗試處理PDF文件並使用使用PDFSharp定義的書籤進行拆分，同時我可以獲取書籤列表，但我無法弄清楚如何實際弄清楚什麼頁碼對應於書籤定義。C＃/ PdfSharp：從書籤條目中找出頁碼並拆分
我正在使用的示例PDF文件在頁面1,5和6中定義了三個頂級書籤，雖然我可以看到帶有以下代碼片段的書籤，但我無法弄清楚將書籤映射到一個頁碼。
代碼：
using (PdfDocument document = PdfReader.Open("test.pdf", PdfDocumentOpenMode.Import))
{
PdfDictionary outline = document.Internals.Catalog.Elements.GetDictionary("/Outlines");
Console.WriteLine("Page count: " + document.PageCount);
foreach(var page in document.Pages)
{
// any hierarchy info on the page itself? doesn't seem to have any.
Console.WriteLine(page.ToString());
}
for (PdfDictionary child = outline.Elements.GetDictionary("/First"); child != null; child = child.Elements.GetDictionary("/Next"))
{
Console.WriteLine(child.Elements.GetString("/Title"));
// FIXME: get page numbers?
}
}
輸出：
Page count: 9
