  • Recent encoder work has improved overall performance so I've gathered up to date segmenter run time data across all quality levels.
  • Using the new data I've updated the thresholds used in AutoPickQuality()
  • Adds a python utility which uses a basic dynamic programming approach to automatically select the buckets which maximize the quality level used across the font collection while meeting the timeout % criteria.
