> Low level toolkit for SVG paths transformations.
Sometimes 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 path data strings,
not with full svg xml sources.

Install
-------

``bash
npm install svgpath
`


Example
-------

`js
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).

$3

Constructor. Creates new SvgPath class instance with chainable methods.
new can be omited.

$3

Similar to Array.from(). Creates SvgPath instance from string or another
instance (data will be cloned).

$3

Converts all path commands to absolute.

$3

Converts all path commands to relative. Useful to reduce output size.

$3

Rescale path (the same as SVG scale transformation). sy = sx by default.

$3

Rescale path (the same as SVG translate transformation). y = 0 by default.

$3

Rotate path to angle degrees around (rx, ry) point. If rotation center not set,
(0, 0) used. The same as SVG rotate transformation.

$3

Skew path along the X axis by degrees angle.

$3

Skew path along the Y axis by degrees angle.

$3

Apply 2x3 affine transform matrix to path. Params - array. The same as SVG
matrix transformation.

$3

Any SVG transform or their combination. For example rotate(90) scale(2,3).
The same format, as described in SVG standard for transform attribute.

$3

Converts smooth curves T/t/S/s with "missed" control point to
generic curves (Q/q/C/c).

$3

Replaces all arcs with bezier curves.

$3

Returns final path string.

$3

Round all coordinates to given decimal precision. By default round to integer.
Useful to reduce resulting output string size.

$3

Apply iterator to all path segments.

- Each iterator receives segment, index, x and y 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.
