ReportLab PDF Generation

Overview

ReportLab is a powerful Python library for programmatic PDF generation. Create anything from simple documents to complex reports with tables, charts, images, and interactive forms.

Two main approaches:

Canvas API (low-level): Direct drawing with coordinate-based positioning - use for precise layouts
Platypus (high-level): Flowing document layout with automatic page breaks - use for multi-page documents

Core capabilities:

Text with rich formatting and custom fonts
Tables with complex styling and cell spanning
Charts (bar, line, pie, area, scatter)
Barcodes and QR codes (Code128, EAN, QR, etc.)
Images with transparency
PDF features (links, bookmarks, forms, encryption)

Choosing the Right Approach

Use Canvas API when:

Creating labels, business cards, certificates
Precise positioning is critical (x, y coordinates)
Single-page documents or simple layouts
Drawing graphics, shapes, and custom designs
Adding barcodes or QR codes at specific locations

Use Platypus when:

Creating multi-page documents (reports, articles, books)
Content should flow automatically across pages
Need headers/footers that repeat on each page
Working with paragraphs that can split across pages
Building complex documents with table of contents

Use Both when:

Complex reports need both flowing content AND precise positioning
Adding headers/footers to Platypus documents (use onPage callback with Canvas)
Embedding custom graphics (Canvas) within flowing documents (Platypus)
