== Release Note ==
XAML export has been rewritten for Inkscape 1.3 using Python.
Initial XAML released in Inkscape 0.4x.


== Design ==
== XAML export==
This export extension uses the XSLT extension system.


== TODO ==
This documentation has been moved to the auto-generated extensions documentation, see [https://inkscape.gitlab.io/extensions/documentation/extensions/svg2xaml.html here].  
*Implement masking and layers blend.
*Improve existing features when possible.
*More tests!


== Discussion ==
[[Category:Developer Documentation]]
 
[[Category:Specification]]
== 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).
