通过Node.js via C++添加带有命名目的书签到PDF

可能的使用场景

命名目标是PDF中特殊类型的书签或链接，不依赖于PDF页面。这意味着，如果PDF中添加或删除页面，书签可能会失效，但命名目标将保持完整。要创建命名目标，请设置 PdfBookmarkEntry.getDestinationName() 属性。

使用命名目标添加PDF书签

请查看以下示例代码，其 源Excel文件，以及 输出PDF文件。屏幕截图显示了输出PDF中的书签和命名目标。屏幕截图还描述了如何查看命名目标，以及您需要Acrobat Reader的专业版。

示例代码

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// Load source Excel file
const dataDir = path.join(__dirname, "data");
const workbook = new AsposeCells.Workbook(path.join(dataDir, "samplePdfBookmarkEntry_DestinationName.xlsx"));

// Access first worksheet
const worksheet = workbook.getWorksheets().get(0);

// Access cell C5
let cell = worksheet.getCells().get("C5");

// Create Bookmark and Destination for this cell
const bookmarkEntry = new AsposeCells.PdfBookmarkEntry();
bookmarkEntry.setText("Text");
bookmarkEntry.setDestination(cell);
bookmarkEntry.setDestinationName("AsposeCells--" + cell.getName());

// Access cell G56
cell = worksheet.getCells().get("G56");

// Create Sub-Bookmark and Destination for this cell
const subbookmarkEntry1 = new AsposeCells.PdfBookmarkEntry();
subbookmarkEntry1.setText("Text1");
subbookmarkEntry1.setDestination(cell);
subbookmarkEntry1.setDestinationName("AsposeCells--" + cell.getName());

// Access cell L4
cell = worksheet.getCells().get("L4");

// Create Sub-Bookmark and Destination for this cell
const subbookmarkEntry2 = new AsposeCells.PdfBookmarkEntry();
subbookmarkEntry2.setText("Text2");
subbookmarkEntry2.setDestination(cell);
subbookmarkEntry2.setDestinationName("AsposeCells--" + cell.getName());

// Add Sub-Bookmarks in list
const list = [];
list.push(subbookmarkEntry1);
list.push(subbookmarkEntry2);

// Assign Sub-Bookmarks list to Bookmark Sub-Entry
bookmarkEntry.getSubEntries = function() {
return this.subEntries || (this.subEntries = []);
};
bookmarkEntry.getSubEntries().push(...list);

// Create PdfSaveOptions and assign Bookmark to it
const opts = new AsposeCells.PdfSaveOptions();
opts.setBookmark(bookmarkEntry);

// Save the workbook in Pdf format with given pdf save options
workbook.save(path.join(dataDir, "outputPdfBookmarkEntry_DestinationName.pdf"), opts);
