Source Formats and Assets

Svg.Skia accepts several input forms:

  • file paths,
  • streams,
  • XML readers,
  • raw SVG strings,
  • Android VectorDrawable XML,
  • Avalonia resource URIs.

SVG files and strings

SKSvg supports:

  • Load(string path)
  • Load(Stream stream, SvgParameters? parameters = null, Uri? baseUri = null)
  • Load(XmlReader reader)
  • FromSvg(string svg)

The Avalonia SvgSource wrappers expose the same idea but add baseUri-aware resource resolution for XAML.

Android VectorDrawable

There are two supported entry points:

  • Load(path) with auto-detection for VectorDrawable XML.
  • LoadVectorDrawable(...) and FromVectorDrawable(...) for explicit VectorDrawable handling.

The repository includes tests that validate accepted and rejected Android attributes, element nesting, and SVG equivalence for representative cases.

CSS injection

Both Avalonia stacks support Css and CurrentCss overlays. This is useful for:

  • recoloring icons without changing the source asset,
  • styling based on control state,
  • mutating the rendered output through resource dictionaries or styles.

SvgParameters carries entity substitutions and CSS fragments when loading.

Resource and URI loading

The Avalonia packages resolve:

  • relative asset paths,
  • avares:// URIs,
  • file URIs,
  • HTTP or HTTPS URLs.

The Skia-backed Avalonia.Svg.Skia.SvgSource also exposes EnableThrowOnMissingResource for stricter missing-resource behavior during development or testing.
