Unifying beziers curves when finding chains returns some arcs in pathContext instead of the bezier seed paths

[ggoodkey]

I am expecting that calling model.findChains with the unifyBeziers option set to true, should return the bezier seeds instead of the individual arcs. However, some links (every other?) in the chain contain the last arc of the curve as the returned pathContext instead. This seems like a bug. The seed is still available by digging through the returned modelContext as a work around

Thanks for posting, can you provide a small repro?

or in the playground

var makerjs = require('makerjs');

this.models = {};
this.models.curve = {
  models:{
    curve1: new makerjs.models.BezierCurve([0, 0], [25, 35], [30, -10], [50, 0]),
    curve2: new makerjs.models.BezierCurve([50, 0], [75, 35], [80, -10], [100, 0])
  }
};

var text = "";
makerjs.model.findChains(this.models.curve, function (chains, loose, layer, ignored) {
  for (var a = 0; a < chains.length; a++) {
    for (var b = 0; b < chains[a].links.length; b++) {
      text = chains[a].links[b].walkedPath.pathContext.type;
      this.models['text_' + b] = {};
      makerjs.model.addCaption(this.models['text_' + b], text, [0, -10 * (b + 1)], [100, -10 * (b + 1)]);
    }
  }
}.bind(this), { unifyBeziers: true });
