Release Note

Initial XAML released in Inkscape 0.4x.

Design

This export extension uses the XSLT extension system.

TODO

  • Implement masking and layers blend.
  • Improve existing features when possible.
  • More tests!

Discussion

Known limitations

Some SVG features are not are partially supported by XAML. When possible, a workaround has been implemented in the export filter to render the missing features. Some elements that can't be created with Inkscape are not supported.

Root level and groups

  • [Not supported] Viewbox.

Defs

  • [Partial] Limited support for switch (always pass).
  • [Not supported] Use.
  • [Not supported] Markers.
  • [Not supported] Patterns.
  • [Not supported] Symbols.

Transforms

  • [Not supported] Multiple values rotation (only the first one is converted).

Filters

  • [Partial] Support limited to blurs (and no support for horizontal/vertical only blur).

Gradients and color

  • [Partial] Some absolute gradients issues.
  • [Not supported] CurrentColor.
  • [Not supported] Fill colors with both an url and a rgb value (the first one is kept).

Stroke

  • [Partial] Mitterlimit doesn't give the same result.
  • [Partial] Shapes render the stroke inside (except line, polyline and polygon). Works as expected with normal paths.

Clip and mask

  • [Partial] PathGeometry is positionned in the object's space (RectangleGeometry works correctly, with absolute values).
  • [Not supported]

Text

  • [Not supported] Text rotation.
  • [Partial] Whitespace handling, issues with xml:whitespace='preserve'.
  • [Partial] Text frames (only works with rectangles, and flowRegion transform not supported).
  • [Not supported] Embedded fonts (in defs).
  • [Not supported] Character rotation.
  • [Not supported] Character positioning (x and y).
  • [Not supported] Text span (from tspan or flowSpan) positioning.
  • [Not supported] Text-anchor.
  • [Not supported] Text stroke.

General workaround for text: convert everything to path before exporting will resolve most issues.

Shapes

  • [Partial]

Images

  • [Not supported] Embedded images (base64).

Other

  • [Not supported] Object title and description.
  • [Not supported] em, ex and % units (XAML only knows pixel values).
  • [Not supported] No RDF and metadata support.
  • [Not supported] DOCTYPE (crashes the XSLT conversion).
