Example 1 with DrawableParent

use of com.facebook.drawee.drawable.DrawableParent in project fresco by facebook.

the class WrappingUtils method maybeApplyLeafRounding.

/**
 * Applies rounding on the drawable's leaf.
 *
 * <p>Currently only {@link BitmapDrawable} or {@link ColorDrawable} leafs can be rounded.
 *
 * <p>If the leaf cannot be rounded, or the rounding params do not specify BITMAP_ONLY mode, the
 * given drawable is returned without being rounded.
 *
 * <p>If the given drawable is a leaf itself, and it can be rounded, then the rounded drawable is
 * returned.
 *
 * <p>If the given drawable is not a leaf, and its leaf can be rounded, the leaf gets rounded, and
 * the original drawable is returned.
 *
 * @return the rounded drawable, or the original drawable if the rounding didn't take place or it
 *     took place on a drawable's child
