Example 8 with PointF

use of android.graphics.PointF in project subsampling-scale-image-view by davemorrissey.

the class SubsamplingScaleImageView method fitToBounds.

/**

     * is set so one dimension fills the view and the image is centered on the other dimension.
     * @param center Whether the image should be centered in the dimension it's too small to fill. While animating this can be false to avoid changes in direction as bounds are reached.
