Pdfminer.six
pdfminer.six is a programmatic tool for extracting text, layout information, and metadata from PDF documents into machine-readable formats. It functions as a document parser that converts internal PDF objects and structures into accessible data objects for analysis.
The project includes utilities for decrypting RC4 and AES encrypted files to enable content extraction. It also provides a layout analyzer to identify fonts, colors, and text locations to determine the organizational structure of pages.
The system covers a broad range of extraction capabilities, including the retrieval of embedded images, interactive form data, and tagged contents. It supports multilingual text processing for diverse character sets and vertical writing, and can transform document data into formats such as HTML, hOCR, or plain text.
Features
- PDF Parsers - Converts internal PDF objects and structures into accessible data objects for programmatic analysis and extraction.
- Document Object Models - Converts binary PDF specifications into a tree of programmable Python objects for structural analysis.
- Multilingual Text Processing - Handles vertical writing and diverse character sets including Chinese, Japanese, and Korean languages.
- Document Layout Analysis - Identifies text locations, fonts, and colors to determine the organizational structure of a page.
- Content Stream Manipulations - Processes document data streams sequentially to decode text and graphics while managing resource references.
- PDF Internal Structure Inspection - Performs low-level analysis of PDF catalogs, trailers, and object cross-reference tables.
- PDF Layout Analysis Tools - Determines the spatial coordinates and bounding boxes of elements to reconstruct page organization.
- PDF Text Extraction - Parses binary PDF files into raw text strings or structured formats for analysis.
- Text Extraction - Retrieves text data directly from the source code, including support for vertical writing and diverse character sets.
- PDF Asset Extractions - Provides tools for retrieving embedded images, fonts, and metadata specifically from PDF documents.
- Unicode Glyph Mapping - Translates internal PDF binary character codes into Unicode strings using embedded font maps and encoding tables.
