SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pypdf, pdfplumber, pdf2image, Pillow, 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, form filling, merging, and OCR error-prone and time-consuming without clear guidance. ## Core Features & Use Cases - PDF Manipulation: Merge, split, rotate, encrypt, decrypt, and watermark PDFs using pypdf, qpdf, and pdftk. - Content Extraction: Extract text, tables, images, and metadata with pdfplumber, pypdf, and poppler-utils, 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 bounding-box validation. - Use Case: Given a stack of scanned application forms, convert them to images, determine field coordinates, validate bounding boxes, and produce filled-in PDFs automatically. ## Quick Start Use the pdf skill to merge the three attached PDF reports into a single document and extract the tables from page two into a spreadsheet.

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 basic text extraction, pypdf's page.extract_text() or the pdftotext command-line tool also work well.

How do I fill out a PDF form programmatically?▼

First run check_fillable_fields.py to detect fillable fields. If present, extract field info and fill with fill_fillable_fields.py; otherwise use extract_form_structure.py and fill_pdf_form_with_annotations.py to place text annotations at computed coordinates.

Which tool should I use to merge or split PDF files?▼

Use pypdf's PdfWriter for Python-based merging and splitting, or qpdf from the command line for fast operations like qpdf --empty --pages file1.pdf file2.pdf -- merged.pdf. pdftk is an alternative if installed.

Can I extract text from a scanned PDF document?▼

Scanned PDFs contain images, not 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 characters like ₀ render as solid boxes. Use the <sub> and <super> XML tags inside Paragraph objects instead.
