Example 63 with PointF

use of android.graphics.PointF in project yellowmessenger-sdk by yellowmessenger.

the class TouchImageView method getZoomedRect.

Example 64 with PointF

use of android.graphics.PointF in project yellowmessenger-sdk by yellowmessenger.

the class TouchImageView method getScrollPosition.

/**
 * Return the point at the center of the zoomed image. The PointF coordinates range
 * in value between 0 and 1 and the focus point is denoted as a fraction from the left
