Some improvements (workarounds for gradients limitations?).
*More tests.
Implement some of the FXG improvements to the XAML export.
*Implement workarounds for gradients limitations (needs exslt). Radial gradient orientation already implemented with exslt math function, but doesn't work with Inkcape currently (works with xsltproc).
*The elliptical arc issue has an easy workaround, but it would be great to implement an arc to curve convertor (see https://github.com/DmitryBaranovskiy/raphael/raw/master/raphael.js for ideas, and http://www.exslt.org/math/index.html for exslt math functions).
*Implement markers support. Should be feasible by passing the object's style attributes to the marker.
*Improve blend mode (screen and lighten add clipping). See if it's possible to use normal blend filters
*Implement some of the FXG improvements to the XAML export.

=== Known limitations ===
Some SVG features are not are partially supported by FXG. 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.

Summary

The goal of this extension is to provide an FXG format export from the File>Save AS dialog. Since Adobe has abandoned SVG support in its Flash applications, Flash developer need a way to create their drawings with Inkscape.

Release Note

Initial XSLT file done. Initial unit and global tests done.

Specification

Design

This export extension uses the XSLT extension system (already used by XAML export).

Discussion

Implementation

TODO

  • More tests.
  • Implement workarounds for gradients limitations (needs exslt). Radial gradient orientation already implemented with exslt math function, but doesn't work with Inkcape currently (works with xsltproc).
  • The elliptical arc issue has an easy workaround, but it would be great to implement an arc to curve convertor (see https://github.com/DmitryBaranovskiy/raphael/raw/master/raphael.js for ideas, and http://www.exslt.org/math/index.html for exslt math functions).
  • Implement markers support. Should be feasible by passing the object's style attributes to the marker.
  • Improve blend mode (screen and lighten add clipping). See if it's possible to use normal blend filters
  • Implement some of the FXG improvements to the XAML export.

Known limitations

Some SVG features are not are partially supported by FXG. 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.

Partial support Not supported
Root level and groups Limited support for nested SVG elements (the first one is converted to Graphics and the others to Groups). Viewbox.
Defs Limited support for switch (always pass). Use.
Markers.
Patterns.
Symbols.
Transforms Skew, multiple values rotation (only the first one is converted).
Filters Support limited to blurs.
Gradients and color Gradient positioning, shaping and transformation (they are currently centered and restricted to the object bounding box).
CurrentColor.
Fill colors with both an url and a rgb value.
Stroke Mitterlimit doesn't give the same result. Dasharrays and dashoffset.
Butt linecap.
Clip and mask clipPathUnits="objectBoundingBox" and maskUnits="objectBoundingBox".
Clipping and masking with text (workaround: convert text to path).
Text Text rotation (0, 90, 180 and 270 degrees only) -> not implemented.
Font weight (normal and bold only) -> values under 500 are considered normal, the others bold.
Whitespace handling, issues with xml:whitespace='preserve'.
Text frames (only works with rectangles, and flowRegion transform not supported).
Generic fonts (workaround: Sans font is converted to Arial).
Embedded fonts (in defs).
Character rotation.
Character positioning (x and y).
Text span (from tspan or flowSpan) positioning.
Text-anchor.
Text stroke.

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

Shapes Polygons.
Polylines.
Elliptical arc curve path commands (workaround: convert ellipse and circle to path first). Converting arcs to curves in XSLT 1.0 looks awfully complex (it requires some exslt math and strings functions -which needs some changes in the Windows build to include and link the exslt dll- and a path parser template).
Images Embedded images (base64).Preserve ratio.
Other Limited support for layers blend mode (screen and lighten add clipping). Object title and description.
em, ex and % units (FXG only knows pixel values).
No RDF and metadata support.
DOCTYPE (crashes the XSLT conversion).
