svg-transformers

Rewrite rules for SVG using Scala's XML API for conversion in mapping applications.

This project is still under development and may change drastically between commits. At this point, this is for demonstration purposes only.

Capabilities

Currently this project can:

• Increase the size of stroke-weights globally by a given factor
• Add a fill to <g> tags that have direct children who possess a user-specified attribute and user-specified values.
  • Attribute can be prefixed/namespaced (eg: namespace:id="4") or unprefixed/namespaced (eg: id="4")
• Accept an SVG from a specified filepath or a URL
• Process the SVG in a streaming fashion

To-Do

• Optimize for performance
• Make a fully command-line accessible application
• Translate zoom levels of a map to stroke-increase factors
• Write more robust tests for edge cases instead of basic sanity checks.
• Write documentation
