Create Benchmark Comparison to Python Alternative

Benchmark Python Alternatives

resvg's existing benchmark offers a set of over 1,600 SVG files, each prepared with an associated PNG baseline for testing standard's compatibility. This will provide us with a reference dataset for establishing our own metrics for comparing to alternative Python libraries against the full set of test images.

Tests should be performed by converting SVGs to both PNGs and PDFs (as separate timing-level benchmarks).

Alternative Methods to Include in Benchmark

• CairoSVG
• Svglib
• Inkscape

Possible Metrics

• Python Dependency Count
• External Dependencies (list of named external dependencies)
• Size of Python Package (including its Python dependencies)
• Size of External Depenencies (cairo, ghostscript, inkscape, etc)
• Speed (total time, lower number is better)
• Memory Usage
• Alpha Channel Support
• Filters Support (see resvg filters support and this example that tests the turbulence filter)
• SVG-to-PNG Compatibility (based on conformance to PNG baseline image)
