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, watermark, and crop PDFs using pypdf, qpdf, and pdftk. - Content Extraction: Extract text, tables, metadata, and embedded images with pdfplumber, pypdfium2, and poppler-utils, including OCR for scanned documents via pytesseract. - PDF Creation & Form Filling: Generate new PDFs with reportlab or pdf-lib, and fill both fillable and non-fillable PDF forms using dedicated scripts with coordinate 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 table from page two.

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 preservation and detect tables via page.extract_tables(). For simple text extraction, pypdf's page.extract_text() or the pdftotext command-line tool also work.

How do I fill a PDF form that has no fillable fields?▼

Extract the form structure with pdfplumber to get label and line coordinates, or convert pages to images and estimate positions visually. Then add text annotations at those bounding boxes using pypdf's FreeText annotations.

What is the difference between pypdf and pdfplumber?▼

pypdf handles structural operations like merging, splitting, rotating, and encryption. pdfplumber specializes in content extraction, providing precise character coordinates and table detection for data extraction tasks.

Can I extract text from a scanned PDF document?▼

Scanned PDFs contain images without a text layer, so standard parsers fail. Convert pages to images with pdf2image, then run OCR with pytesseract to recover the text content.

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

ReportLab's built-in fonts lack Unicode subscript and superscript glyphs, rendering them 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 with the --empty --pages syntax to merge files or select page ranges, and --split-pages to divide a document. pdftk offers similar cat and burst operations if installed.
