one_dollar_unistroke_recognizer 0.6.0

The $1 Unistroke Recognizer, a 2D single-stroke recognizer. This is a Dart port of the original JavaScript implementation.

0.6.0

• Added a line template, and the corresponding RecognizedUnistroke.convertToLine() method.

0.5.0

• RecognizedUnistroke.name is now using an enum instead of a string, e.g. DefaultUnistrokeNames.circle instead of 'circle'. If you're using custom unistrokes, see the README for how to use the recognizeUnistrokeOfType method.
• convertToCanonicalPolygon() now returns a correctly rotated shape (https://github.com/adil192/one_dollar_unistroke_recognizer/issues/2).

0.4.2

• Removed colored text from README since it doesn't work on pub.dev.

0.4.1

• Fixed images in the README on pub.dev.
• Added a RecognizedUnistroke.convertToOval() method.

0.4.0

• This release has changed the default set of templates to contain better shapes. The old templates are still available in example$1Unistrokes. The new templates are only a circle, rectangle, and triangle, where the old templates were more varied but were also sketched by hand and were not very pretty.
• Inputs are now recognized even if they are drawn in the opposite direction of the template. For example, a clockwise circle will be recognized as a circle, even if the template is a counter-clockwise circle. This wasn't the case in previous releases.
• Like previous releases, convertToCanonicalPolygon() is still returning incorrectly rotated shapes. See https://github.com/adil192/one_dollar_unistroke_recognizer/issues/2 to track progress on this issue.

0.3.1

• Scores can now only be between 0 and 1. Would-be negative scores are interpreted to mean that the stroke is not recognized, so null is returned.

0.3.0

• Added functions to RecognizedUnistroke to get a "perfect" shape from the user's stroke: see RecognizedUnistroke.convertToCanonicalPolygon and RecognizedUnistroke.convertToCircle.

0.2.0

• Recognize custom unistrokes by setting the referenceUnistrokes variable, or by passing the overrideReferenceUnistrokes parameter to recognizeUnistroke.

0.1.1

• feat: Added a web demo here: https://adil192.github.io/one_dollar_unistroke_recognizer.
• feat: You can see the list of possible outputs in knownUnistrokesNames.
• fix: Strokes that are too short are ignored.

0.1.0

• Initial release.
• TODO: Allow adding custom unistrokes.
