## <a name='Related_Function'>Related_Function</a>


SkRRect global, <code>struct</code>, and <code>class</code> related member functions share a topic.
<table style='border-collapse: collapse; width: 62.5em'>
  <tr><th style='text-align: left; border: 2px solid #dddddd; padding: 8px; '>Topic</th>
<th style='text-align: left; border: 2px solid #dddddd; padding: 8px; '>Description</th></tr>

  </tr>
</table>

The <a href='#SkRRect'>SkRRect</a> class represents a rounded rect with a potentially different
radii for each corner. It does not have a constructor so must be
initialized with one of the initialization functions (e.g., <a href='#SkRRect_setEmpty'>setEmpty</a>,
<a href='#SkRRect_setRectRadii'>setRectRadii</a>, etc.)

This class allows implementing CSS properties that describe rounded corners.
A rectangle may have up to eight radii, one for each axis on each of its four
corners.

If either corner's radii are zero, the corner is square.
Negative radii are treated as zero.
If corner curves overlap, they are proportionally reduced to fit.

Calls inset on the bounds, and adjust the radii to reflect what happens.
If the corner is sharp (no curvature), leave it alone,
otherwise we grow/shrink the radii by the amount of the inset. If a
given radius becomes negative, it is pinned to 0.
If the inset amount is larger than the width/height then the rrect collapses to
a degenerate line or point.
If the inset is sufficiently negative to cause the bounds to become infinite then
the result is a default initialized rrect.
