SVG path operations library


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.

npm install svgpath
var svgpath = require('svgpath');
var transformed = svgpath(__your_path__)

All methods are chainable (return self).

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

Converts all path commands to absolute.

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

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

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

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

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

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

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

Replaces all arcs with bezier curves.

Returns final path string.

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

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.
