Example 1 with GridSampler

use of com.google.zxing.common.GridSampler in project zxing by zxing.

the class Detector method sampleGrid.

/**
   * Creates a BitMatrix by sampling the provided image.
   * topLeft, topRight, bottomRight, and bottomLeft are the centers of the squares on the
   * diagonal just outside the bull's eye.
   */
private BitMatrix sampleGrid(BitMatrix image, ResultPoint topLeft, ResultPoint topRight, ResultPoint bottomRight, ResultPoint bottomLeft) throws NotFoundException {
    GridSampler sampler = GridSampler.getInstance();
    int dimension = getDimension();
    float low = dimension / 2.0f - nbCenterLayers;
    float high = dimension / 2.0f + nbCenterLayers;
    return sampler.sampleGrid(image, dimension, dimension, // topleft
