lowerTransformations :: SVG -> SVG

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

lowerIds :: SVG -> SVG

Remove all id attributes.

simplify :: SVG -> SVG

Optimize SVG tree without affecting how it is rendered.

removeGroups :: SVG -> [SVG]

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 ]

extractPath :: SVG -> [PathCommand]

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

withSubglyphs :: [Int] -> (SVG -> SVG) -> SVG -> SVG

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)]

splitGlyphs :: [Int] -> SVG -> (SVG, SVG)

Split symbols.

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

svgGlyphs :: SVG -> [(SVG -> SVG, DrawAttributes, SVG)]

Split symbols and include their context and drawing attributes.

pathify :: SVG -> SVG

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)
      ]
    ]

mapSvgPaths :: ([PathCommand] -> [PathCommand]) -> SVG -> SVG

Map over all recursively-found path commands.

mapSvgLines :: ([LineCommand] -> [LineCommand]) -> SVG -> SVG

Map over all recursively-found line commands.

mapSvgPoints :: (RPoint -> RPoint) -> SVG -> SVG

Map over all line command control points.

svgPointsToRadians :: SVG -> SVG

Convert coordinate system from degrees to radians.
