# Documentation

lowerTransformations :: SVG -> SVG Source #

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

clearDrawAttributes :: SVG -> SVG Source #

Remove all draw attributes such as `stroke`

, `fill`

and 'fill-opacity'.

removeGroups :: SVG -> [SVG] Source #

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] Source #

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

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

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) Source #

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)] Source #

Split symbols and include their context and drawing attributes.

pathify :: SVG -> SVG Source #

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 Source #

Map over all recursively-found path commands.

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

Map over all recursively-found line commands.

svgPointsToRadians :: SVG -> SVG Source #

Convert coordinate system from degrees to radians.

module Reanimate.Svg.Constructors

module Reanimate.Svg.LineCommand

boundingBox :: Tree -> (Double, Double, Double, Double) Source #

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. All other nodes return (0,0,0,0).

svgHeight :: Tree -> Double Source #

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