Crate rpdfium_edit 

PDF editing and writing for rpdfium — a faithful Rust port of PDFium.

This crate implements PDF editing capabilities:

• Object serialization: PDF objects → byte output
• Stream encoding: Flate compression for output streams
• EditDocument: Mutable overlay on top of immutable ObjectStore
• PDF writing: Full rewrite and incremental save
• Page management: Add, delete, move pages; insert page objects
• Content generation: Paths, text, images → content stream operators
• Annotation editing: Create, modify, delete annotations
• Form persistence: Update form field values
• Encryption output: Re-encrypt modified documents

Design

The core pattern is a mutable overlay (EditDocument) that layers modifications on top of an existing immutable ObjectStore. This preserves the read-only design of the parser while enabling editing.

N-up page export — arrange multiple source pages in a grid on fewer dest pages.

cpdf_pagecontentgenerator

Content stream generation — converts PageObjects to PDF content stream bytes.

cpdf_pageexporter

Page export — deep-clone pages from one document into another.

document
