PDF Renderer

High-performance PDF generation as an alternative to ReportLab:

# Use Rust backend (automatically detected when installed)
doc.to_pdf("output.pdf", use_rust=True)

Benefits:

EMF/WMF Converter

Convert Windows Enhanced Metafile (EMF) and Windows Metafile (WMF) to SVG:

import docquill_rust

# Convert file
docquill_rust.convert_emf_to_svg("input.emf", "output.svg")

# Convert bytes to SVG string
svg_content = docquill_rust.convert_emf_bytes_to_svg(emf_bytes)

Supported formats:

• EMF (Enhanced Metafile)
• EMF+ (GDI+ Enhanced Metafile)
• WMF (Windows Metafile)
• WMF with embedded EMF

Performance: ~50x faster than Java-based converters (FreeHEP/Apache POI)
