| /** |
| * This class attempts to find alignment patterns in a QR Code. Alignment patterns look like finder |
| * patterns but are smaller and appear at regular intervals throughout the image. |
| * |
| * At the moment this only looks for the bottom-right alignment pattern. |
| * |
| * This is mostly a simplified copy of {@link FinderPatternFinder}. It is copied, |
| * pasted and stripped down here for maximum performance but does unfortunately duplicate |
| * some code. |
| * |
| * This class is thread-safe but not reentrant. Each thread must allocate its own object. |
