핵심 아키텍처 및 수학 공식
New PDF = Traverse(Root Catalog) ➔ Isolate(Page Tree Nodes) ➔ Recompile(Binary Stream)
A PDF is not a flat file; it is a complex hierarchy of interconnected objects (fonts, images, annotations). Splitting requires isolating the specific 'Page' objects and carefully copying only their necessary dependencies.
모범 사례 및 필수 지침
- Remove Extraneous Pages Before Sharing: If you are sending a massive 500 page financial prospectus to a client, always split and send only the 5 relevant pages. This reduces their cognitive load and your email attachment size.
- Verify Embedded Font Subsets: When extracting a single page, the tool must carry over the specific font subset required to render the text. Always visually verify the split document to ensure characters are not missing.
- Understand Bookmark Destruction: Splitting a PDF often destroys the document's interactive Table of Contents (bookmarks), because the linked destination pages no longer exist in the new file.
자주 묻는 질문 (FAQ)
Why did the split file size not decrease proportionally?
If a 100 page PDF contains a single massive 10MB embedded font used on every page, extracting just page 1 will still result in a 10MB file, because the entire font object must be copied over.
Can I extract non contiguous pages?
Yes. Advanced splitting tools allow you to specify exact comma separated arrays (e.g., '1, 5, 9-12') to build a custom composite document.
Does splitting remove PDF passwords?
No. If a document is encrypted with an owner password restricting extraction, you cannot mathematically parse the binary tree without supplying the decryption key first.
