Package Exports
- svgpath
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (svgpath) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
svgpath
Low level toolkit for SVG paths transformations. Sometime you can't use
transform
attributes and have to apply changes to svg paths directly. Then this package is for you :) !
Note, this package works with paths
, not with svg xml sources.
Install
npm install svgpath
Example
var svgpath = require('svgpath');
var transformed = svgpath(__your_path__)
.scale(0.5)
.translate(100,200)
.rel()
.round(1)
.toString();
API
All methods are chainable (return self).
new SvgPath(path) -> self
Constructor. Creates new SvgPath
class instance with chainable methods.
new
can be omited.
.abs() -> self
Converts all path commands to absolute.
.rel() -> self
Converts all path commands to relative. Useful to reduce output size.
.scale(sx [, sy]) -> self
Rescale path (the same as SVG scale
transformation). sy
= sx
by default.
.translate(x [, y]) -> self
Rescale path (the same as SVG translate
transformation). y
= 0 by default.
.rotate(angle [, rx, ry]) -> self
Rotate path to angle
degree around (rx, ry) point. If rotation center not set,
(0, 0) used. The same as SVG rotate
transformation.
.matrix([ m1, m2, m3, m4, m5, m6 ]) -> self
Apply 2x3 affine transform matrix to path. Params - array. The same as SVG
matrix
transformation.
.transform(string) -> self
Any SVG transform or their combination. For example rotate(90) scale(2,3)
.
The same format, as described in SVG standard for transform
attribute.
.unshort() -> self
Converts smooth curves T
/t
/S
/s
with "missed" control point to
generic curves (Q
/q
/C
/c
).
.unarc() -> self
Replaces all arcs with bezier curves.
.toString() -> string
Returns final path string.
.round(precision) -> self
Round all coordinates to given decimal precision. By default round to integer. Useful to reduce resulting output string size.
.iterate(function(segment, index, x, y) [, keepLazyStack]) -> self
Apply iterator to all path segments.
- Each iterator receives
segment
,index
,x
andy
params. Where (x, y) - absolute coordinates of segment start point. - Iterator can modify current segment directly (return nothing in this case).
- Iterator can return array of new segments to replace current one (
[]
means that current segment should be delated).
If second param keepLazyStack
set to true
, then iterator will not evaluate
stacked transforms prior to run. That can be useful to optimize calculations.
