reportlab-enhanced

中文

An enhanced fork of ReportLab — the open-source Python library for generating PDF documents, charts, and vector graphics.

Features

• Generate rich PDF documents with text, images, tables, and charts
• High-level layout engine (Platypus) with flowables, frames, and page templates
• Low-level Canvas API for direct PDF drawing operations
• Charts and graphics with SVG/PS/bitmap rendering support
• TrueType and Type1 font handling
• Enhanced: TrueType font fallback support for missing glyphs
• Pure Python (no C extensions required since v4.0)
• Python >= 3.9

Enhancements over upstream

This fork builds on ReportLab 4.x with additional features:

• TTFont Fallback: Automatic font fallback for missing glyphs in TrueType fonts, controlled via environment variable REPORTLAB_FONT_FALLBACK=1
• Active development with improvements to font handling and CJK support

See CHANGES.md for the full changelog.

Optional dependencies

pip install reportlab-enhanced[accel]      # rl_accel acceleration
pip install reportlab-enhanced[renderpm]   # rl_renderPM bitmap rendering
pip install reportlab-enhanced[pycairo]    # Cairo-based rendering

Quick Start

from reportlab.lib.pagesizes import A4
from reportlab.pdfgen import canvas

c = canvas.Canvas("hello.pdf", pagesize=A4)
c.drawString(100, 750, "Hello, reportlab-enhanced!")
c.save()

For the high-level Platypus API:

from reportlab.lib.pagesizes import A4
from reportlab.platypus import SimpleDocTemplate, Paragraph
from reportlab.lib.styles import getSampleStyleSheet

doc = SimpleDocTemplate("doc.pdf", pagesize=A4)
styles = getSampleStyleSheet()
story = [Paragraph("Hello, reportlab-enhanced!", styles["Title"])]
doc.build(story)

Documentation

The original ReportLab documentation is available at docs.reportlab.com.

To build the included PDF manuals:

cd docs && python genAll.py

This generates three PDF references in the docs/ directory.

Development

This project extensively uses vibe coding with Claude Code (Anthropic Claude) as a development partner for code generation, refactoring, and documentation.

Running tests

python setup.py tests-preinstall
# or
cd tests && python runAll.py
