技術アーキテクチャと実行の仕組み
PDF Object Catalog Merging
The merge engine instantiates a target PDFDocument, parses each source document's cross-reference catalog, copies referenced page dictionary trees and font subsets, and rebuilds unified object indices in binary memory.
Merged_Doc = await PDFDocument.create();
for (const doc of docs) { const pages = await Merged_Doc.copyPages(doc, doc.getPageIndices()); pages.forEach(p => Merged_Doc.addPage(p)); }技術的な制限と運用上の制約
- Password-encrypted PDFs must have passwords removed prior to merging.
- Digitally signed PDFs: Merging documents creates a modified composite file and invalidates individual cryptographic signatures.
