Methods

aboutEquals(double moduleSize, double i, double j) → bool
Determines if this finder pattern "about equals" a finder pattern at the stated position and size -- meaning, it is at nearly the same center with nearly the same size.
combineEstimate(double i, double j, double newModuleSize) → FinderPattern
Combines this object's current estimate of a finder pattern position and module size with a new estimate. It returns a new FinderPattern containing a weighted average based on count.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
