3.0.0

This version brings elm-geometry-svg up to date with elm-geometry 3.0, and relaxes the restriction that input geometry must be in Pixels. It is often useful to create SVG elements using real-world units, and then later on apply a scaling factor to convert to pixels for final display (see #14 for some related discussion - thanks @MartinSStewart!).

Rendering with different units types is now possible with the elm-geometry-svg API, although with the side effect that you now have to be a bit more careful to make sure the units work out correctly - since as soon as you convert from (for example) a Circle2d Meters WorldCoordinates to a plain Svg Msg value, you lose compile-time checking of units and coordinate systems.

Also note that regardless of whether you use meters, centimeters, feet or some other Length unit to construct your geometry, the actual SVG coordinate values generated will always be in meters; for example, a Point2d.feet 1 2 might end up getting written out to SVG as the coordinates "0.3048,0.6096" since 1 foot is 0.3048 meters. However, in most cases you should be able to use the new Svg.at and Svg.at_ functions to explicitly apply a conversion factor from whatever units you want (centimeters, inches etc.) to pixels; see the API documentation for details.

2.0.0

elm-geometry-svg 2.0.0 is out! The breaking change is that elm-geometry-svg is now based on elm-geometry 2.0 (with units and coordinate systems support). In addition, this release adds Svg.rectangle2d for proper rectangle drawing.

1.0.0

elm-geometry-svg 1.0 is out! This replaces opensolid/svg, although with a slightly narrower focus. The high-level point2d, vector2d, direction2d, text2d and render2d functions have been removed, leaving only the functions where the translation to SVG elements is fairly direct, obvious and unambiguous:

• Geometry drawing functions such as lineSegment2d and cubicSpline2d
• Transformation functions such as rotateAround and mirrorAcross

If you do need to use the old text2d, vector2d, render2d etc. functions, you can copy/adapt the opensolid/svg implementations into your own code. Any questions, please send me (@ianmackenzie) a message in the Elm Slack!
