pdf-rs/pdf
This library is a toolkit for processing, manipulating, and inspecting PDF documents within the Rust programming language. It provides programmatic access to the internal structure of files, enabling the extraction of data and the modification of document content.
The project utilizes a strongly-typed system to map complex document objects into structured data models. It supports the parsing of existing files through lazy-loading and stream-based decoding, which allows for the retrieval of text, metadata, and images. The library also facilitates the creation of updated document versions by restructuring internal components and saving changes to files.
Beyond core processing, the library includes utilities for debugging and analyzing document composition. Developers can inspect and visualize the internal hierarchy of a file as an interactive tree of primitives to troubleshoot rendering issues or verify document structure.
Features
- PDF Libraries - Provides a Rust-based library for reading, manipulating, and writing PDF files.
- PDF Text Extractors - Parses PDF files to extract text, metadata, and images for programmatic data processing.
- Document-to-Object Mappings - Implements lazy-loading of document objects to minimize memory usage when parsing complex PDF structures.
- Document Parsing Services - Provides programmatic methods to parse and extract internal data from PDF documents for further processing.
- PDF Content Editing - Enables direct modification of PDF content by updating internal structures and saving changes to the file.
- PDF Document Management - Provides comprehensive tools for manipulating PDF files, including restructuring pages and updating internal content.
- Internal Object Manipulation - Provides a toolkit for programmatically extracting data and modifying the internal binary structures of PDF files.
- Incremental File Updating - Supports incremental file updates by appending new object streams and updating cross-reference tables to preserve document integrity.
- PDF Internal Structure Inspection - Visualizes the internal hierarchy of PDF files as an interactive tree to assist with debugging document composition.
- Document Element Inspection - Allows developers to inspect and navigate the internal hierarchy of PDF documents during development.
- Interactive File Modifiers - Facilitates the creation of updated document versions by restructuring internal components and saving changes.
- Binary Stream Decoding - Decodes compressed binary PDF streams using filter-specific algorithms to transform raw data into readable content.
