SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pypdf, pdfplumber, pdf2image, Pillow, pytesseract, reportlab, pypdfium2, and includes scripts (resource) and references (resource) components.

What problem does it solve? Working with PDF files programmatically is fragmented across many libraries and tools, making tasks like text extraction, merging, form filling, and OCR error-prone and time-consuming without clear guidance. ## Core Features & Use Cases - PDF Manipulation: Merge, split, rotate, encrypt, decrypt, watermark, and crop PDFs using pypdf, qpdf, and pdftk. - Content Extraction: Extract text, tables, metadata, and embedded images with pdfplumber, pdftotext, and pdfimages, including OCR for scanned documents via pytesseract. - PDF Creation & Form Filling: Generate new PDFs with reportlab and fill both fillable and non-fillable PDF forms using dedicated scripts with coordinate validation. - Use Case: Given a stack of scanned vendor invoices, convert them to images, run OCR to extract text, pull out table data into a spreadsheet, and merge the results into a single report PDF. ## Quick Start Ask the assistant to extract all text and tables from your PDF file, or to merge several PDFs into one document.

Frequently Asked Questions about pdf

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I extract text and tables from a PDF in Python?▼

Use pdfplumber to extract text with layout preserved and to detect tables via page.extract_tables(). For plain text only, pdftotext from poppler-utils is faster, and pypdf handles basic text and metadata extraction.

How do I fill out a PDF form programmatically?▼

First run check_fillable_fields.py to detect form fields. Fillable PDFs are completed with fill_fillable_fields.py using extracted field IDs, while non-fillable PDFs are filled with text annotations via fill_pdf_form_with_annotations.py using validated bounding boxes.

What is the difference between pypdf, pdfplumber, and reportlab?▼

pypdf handles structural operations like merging, splitting, rotating, and encryption. pdfplumber specializes in extracting text and tables with precise coordinates. reportlab is used to create new PDF documents from scratch.

Can I extract text from a scanned PDF?▼

Scanned PDFs contain images rather than text layers, so standard parsers fail. Convert pages to images with pdf2image, then run OCR with pytesseract to produce searchable text.

Why do subscript characters render as black boxes in reportlab PDFs?▼

ReportLab's built-in fonts lack Unicode subscript and superscript glyphs, so those characters render as solid boxes. Use the <sub> and <super> XML markup tags inside Paragraph objects instead.

How do I merge or split PDFs from the command line?▼

Use qpdf: merge with 'qpdf --empty --pages file1.pdf file2.pdf -- merged.pdf' and split page ranges with 'qpdf input.pdf --pages . 1-5 -- out.pdf'. pdftk offers equivalent cat and burst operations if installed.
