svgpath
Low level toolkit for SVG paths transformations. Sometimes you can't use
transformattributes 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
npm install svgpathExample
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.
SvgPath.from(path|SvgPath) -> self
Similar to Array.from(). Creates SvgPath instance from string or another
instance (data will be cloned).
.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 degrees around (rx, ry) point. If rotation center not set,
(0, 0) used. The same as SVG rotate transformation.
.skewX(degrees) -> self
Skew path along the X axis by degrees angle.
.skewY(degrees) -> self
Skew path along the Y axis by degrees angle.
.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,xandyparams. 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.
