Fixed

• Fix robustness issues relating to near-zero determinant in R, TS, TR, and TSR estimators (#31)
• Repair error message bug in nudged.estimate (#37)

Migration Tips

The TS, TR, and TSR estimators now always fall back to translation when domain and range provide only a single point pair for estimation. Previously this was not guaranteed in rare edge cases due to floating point rounding errors. Therefore, if your application had some additional checks to choose T for single point situations over TS, TR or TSR, those additional checks can now be safely removed.

2.0.0

Complete codebase rewrite. In short:

• Pure functional approach. No object-oriented code.
• Use { x: 1, y: 2 } instead of [ 1, 2 ] to denote a point.
• Use { a: 1, b: 2, x: 3, y: 4 } instead of Transform to denote a transform.
• Rearrange code and API into submodules
• New analysis tools: mse, rss
• Switched from ES5 to ES6: const and let instead of var etc
• Switched testing framework from mocha to tape
• High quality generated API documentation

1.6.0

New features:

• nudged.createFromString enables creating a Transform from CSS matrix string

Other improvements

• Reparied weird characters in docs

1.5.0

New translation estimators:

Changes in development:

• CI integration is migrated from travis-ci.org to travis-ci.com.
• Git workflow updated, development branch dropped

1.4.0

Changes:

• alias for Transform.equals(): Transform.equal()
• a new method Transform.almostEqual()
• expose Transform.EPSILON
• use prototype in Transform instead of patching

Fixes a floating point bug in estimateTR

1.3.0

No breaking changes. Additions:

• multiplyRight alias multiplyBy
• Prebuilt transformations Transform.R90, .R180, .R270, and .X2
• New transformation type I

Developmental changes:
