|
|
|
<a href='#IRect'>IRects</a> intersect when they enclose a common area. To intersect, each of the pair
|
|
must describe area; <a href='#SkIRect_fLeft'>fLeft</a> is less than <a href='#SkIRect_fRight'>fRight</a>, and <a href='#SkIRect_fTop'>fTop</a> is less than <a href='#SkIRect_fBottom'>fBottom</a>;
|
|
<a href='SkIRect_Reference#SkIRect'>SkIRect</a>::<a href='#SkIRect_isEmpty'>isEmpty</a>() returns false. The intersection of <a href='SkIRect_Reference#IRect'>IRect</a> pair can be described by:
|
|
<code>(<a href='undocumented#max()'>max</a>(a.<a href='#SkIRect_fLeft'>fLeft</a>, b.<a href='#SkIRect_fLeft'>fLeft</a>), <a href='undocumented#max()'>max</a>(a.<a href='#SkIRect_fTop'>fTop</a>, b.<a href='#SkIRect_fTop'>fTop</a>),

|
|
|
|
The intersection is only meaningful if the resulting <a href='SkIRect_Reference#IRect'>IRect</a> is not empty and
|
|
describes an area: <a href='#SkIRect_fLeft'>fLeft</a> is less than <a href='#SkIRect_fRight'>fRight</a>, and <a href='#SkIRect_fTop'>fTop</a> is less than <a href='#SkIRect_fBottom'>fBottom</a>.

If <a href='#SkIRect_adjust_dL'>dL</a> is positive, narrows <a href='SkIRect_Reference#SkIRect'>SkIRect</a> on the left. If negative, widens it on the left.

If <a href='#SkIRect_adjust_dT'>dT</a> is positive, shrinks <a href='SkIRect_Reference#SkIRect'>SkIRect</a> on the top. If negative, lengthens it on the top.

The resulting <a href='SkIRect_Reference#SkIRect'>SkIRect</a> is not checked for validity. Thus, if the resulting <a href='SkIRect_Reference#SkIRect'>SkIRect</a> left is
