Package Exports

normalize-path-scale

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 (normalize-path-scale) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

normalize-path-scale

Normalizes a 2D path to its bounding box. This is useful to take a series of paths (e.g. SVG) and normalize them all into the -1.0 .. 1.0 range, for easier rendering. It also makes it more suitable for rendering SVG paths in 3D space with WebGL.

Also corrects aspect ratio.

var discretize = require('discretize-svg-path')
var parse = require('parse-svg-path')
var normalize = require('normalize-path-scale')

//parse into usable array
var path = parse(svgContents)

//approximate into discrete points
var points = discretize(path)

//normalize to -1.0 .. 1.0
points = normalize(points)

//render with webgl / canvas / etc
//...

Usage

normalize(path[, bounds])

Produces a new path (with new points) from the original 2D path, but scaled based on its bounding box so that all points are within the range of -1.0 to 1.0. This also maintains the original aspect ratio of the path.

You can specify bounds for a custom bounding box which has the following members: { minX, minY, maxX, maxY } -- if no bounds is specified, it will be computed with getboundingbox.

var path = normalize([ [20,20], [10,10], [40,-50] ])
