## <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'>

<a href='#SkRRect'>SkRRect</a> describes a rounded rectangle with a bounds and a pair of radii for each corner.
The bounds and radii can be set so that <a href='#SkRRect'>SkRRect</a> describes a rectangle with sharp corners,
a <a href='undocumented#Circle'>Circle</a>, an <a href='undocumented#Oval'>Oval</a>, or a rectangle with one or more rounded corners.
<a href='#SkRRect'>SkRRect</a> allows implementing CSS properties that describe rounded corners.
<a href='#SkRRect'>SkRRect</a> may have up to eight different radii, one for each axis on each of its four
corners.
<a href='#SkRRect'>SkRRect</a> may modify the provided parameters when initializing bounds and radii.
If either axis radii is zero or less, radii are stored as zero; corner is square.
If corner curves overlap, radii are proportionally reduced to fit within bounds.

void <a href='#SkRRect_outset'>outset</a>(<a href='undocumented#SkScalar'>SkScalar</a> dx, <a href='undocumented#SkScalar'>SkScalar</a> dy)
</pre>
Outsets bounds by <a href='#SkRRect_outset_2_dx'>dx</a> and <a href='#SkRRect_outset_2_dy'>dy</a>, and adjusts radii by <a href='#SkRRect_outset_2_dx'>dx</a> and <a href='#SkRRect_outset_2_dy'>dy</a>. <a href='#SkRRect_outset_2_dx'>dx</a> and <a href='#SkRRect_outset_2_dy'>dy</a> may be
positive, negative, or zero.
If either corner radius is zero, the corner has no curvature and is unchanged.
Otherwise, if adjusted radius becomes negative, pins radius to zero.
If <a href='#SkRRect_outset_2_dx'>dx</a> exceeds half bounds width, bounds left and right are set to
bounds x-axis center. If <a href='#SkRRect_outset_2_dy'>dy</a> exceeds half bounds height, bounds top and
bottom are set to bounds y-axis center.
If <a href='#SkRRect_outset_2_dx'>dx</a> or <a href='#SkRRect_outset_2_dy'>dy</a> cause the bounds to become infinite, bounds is zeroed.
### Parameters
