svg2ooxml 0.8.1

SVG-to-PowerPoint converter with native, editable PresentationML output.

svg2ooxml

SVG-to-PowerPoint converter with native, editable PresentationML output.

---

svg2ooxml parses SVG markup, builds a typed intermediate representation, renders native DrawingML XML fragments, and packages them into valid .pptx files. Shapes, text, gradients, filters, masks, clipping paths, and SMIL animations are converted to editable PowerPoint objects — not rasterized images.

svg2ooxml is the converter package. PowerPoint behavior research, authored control decks, and durable oracle evidence are maintained in the companion repository openxml-audit so the package documentation can stay focused on conversion.

The same distribution also carries figma2gslides, a tool package built on top of the converter for Figma and Google Slides workflows. It is intentionally separate from the supported svg2ooxml converter API.

Features

• Native DrawingML output — shapes, text, and paths render as editable PowerPoint objects
• SMIL animation support — entrance, emphasis, exit, and motion path animations
• SVG filter effects — blur, drop shadow, color matrix, and compositing
• Gradients & patterns — linear, radial, and pattern fills with correct coordinate transforms
• Masks & clipping — SVG clip paths and masks mapped to OOXML equivalents
• Multi-slide export — split multi-page SVGs into separate slides
• Extensible pipeline — service registry with dependency injection for custom providers

Installation

Requires Python 3.13 or newer.

The base install does not depend on NumPy. NumPy is installed only through the render, color, or accel extras for raster/filter/color workloads.

pip install svg2ooxml

Optional extras:

pip install svg2ooxml[render]    # Skia rendering + visual comparison
pip install svg2ooxml[color]     # Advanced color space support
pip install svg2ooxml[figma2gslides]  # Figma/Google Slides tool runtime

Current Release

0.8.1 is the typed CSS value, calc coverage, and parser-hardening release. It keeps the 0.8 fidelity policy and tracing work intact while centralizing more authored numeric parsing across colors, gradients, filters, masks, transforms, text, and animation values. ADR-036 defines the measured-fidelity road to 0.9.

Quick Start

from svg2ooxml import SvgToPptxExporter

exporter = SvgToPptxExporter()
exporter.export("input.svg", "output.pptx")

CLI

svg2ooxml convert input.svg -o output.pptx

How It Works

SVG text
  → SVGParser.parse()            → ParseResult (lxml tree + metadata)
  → convert_parser_output()      → IRScene (typed intermediate representation)
  → DrawingMLWriter.render()     → DrawingMLRenderResult (XML fragments + assets)
  → PPTXPackageBuilder.write()   → .pptx file
