- __construct() : mixed
- aboutEquals() : 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() : self
- Combines this object's current estimate of a finder pattern position and module size with a new estimate. It returns a new FinderPattern containing an average of the two.
