Remove transformations (such as translations, rotations, scaling) and apply them directly to the SVG nodes. Note, this function may convert nodes (such as Circle or Rect) to paths. Also note that does change how the SVG is rendered. Particularly, stroke width is affected by directly applying scaling.

lowerTransformations (scale 2 (mkCircle 1)) = mkCircle 2

Remove all id attributes.

Remove all draw attributes such as stroke, fill and 'fill-opacity'.

Optimize SVG tree without affecting how it is rendered.

Separate grouped items. This is required by clip nodes.

removeGroups (withFillColor "blue" $ mkGroup [mkCircle 1, mkRect 1 1])
    = [ withFillColor "blue" $ mkCircle 1
      , withFillColor "blue" $ mkRect 1 1 ]

Extract all path commands from a node (and its children) and concatenate them.

Map over indexed symbols.

withSubglyphs [0,2] (scale 2) (mkGroup [mkCircle 1, mkRect 2, mkEllipse 1 2])
      = mkGroup [scale 2 (mkCircle 1), mkRect 2, scale 2 (mkEllipse 1 2)]

Split symbols.

splitGlyphs [0,2] (mkGroup [mkCircle 1, mkRect 2, mkEllipse 1 2])
      = ([mkRect 2], [mkCircle 1, mkEllipse 1 2])

Split symbols and include their context and drawing attributes.

Convert primitive SVG shapes (like those created by mkCircle, mkRect, mkLine or mkEllipse) into SVG path. This can be useful for creating animations of these shapes being drawn progressively with partialSvg.

Example:

pathifyExample :: Animation
pathifyExample = animate $ \t -> gridLayout
    [ [ partialSvg t $ pathify $ mkCircle 1
      , partialSvg t $ pathify $ mkRect 2 2
      ]
    , [ partialSvg t $ pathify $ mkEllipse 1 0.5
      , partialSvg t $ pathify $ mkLine (-1, -1) (1, 1)
      ]
    ]

Map over all recursively-found path commands.

Map over all recursively-found line commands.

Map over all line command control points.

Convert coordinate system from degrees to radians.

Return bounding box of SVG tree. The four numbers returned are (minimal X-coordinate, minimal Y-coordinate, width, height)

Note: Bounding boxes are computed on a best-effort basis and will not work in all cases. The only supported SVG nodes are: path, circle, polyline, ellipse, line, rectangle, image and svg. All other nodes return (0,0,0,0). The box for the svg node is based on the document's width and height (if both are present).

Height of SVG node in local units (not pixels). Computed on best-effort basis and will not give accurate results for all SVG nodes.

Width of SVG node in local units (not pixels). Computed on best-effort basis and will not give accurate results for all SVG nodes.

Replace all use nodes with their definition.

Transform out viewbox. Definitions and CSS rules are discarded.

Transform out viewbox and fit image to screen size.

Embed Document. This keeps the entire document intact but makes it more difficult to use, say, pathify on it.
