# <a name="Rect"></a> Rect

# <a name="SkRect"></a> Struct SkRect
<a href="#SkRect">SkRect</a> holds four <a href="undocumented#SkScalar">SkScalar</a> coordinates describing the upper and
lower bounds of a rectangle. <a href="#SkRect">SkRect</a> may be created from outer bounds or
from position, <a href="#SkRect_width">width</a>, and <a href="#SkRect_height">height</a>. <a href="#SkRect">SkRect</a> describes an area; if its <a href="#SkRect_right">right</a>
is less than or equal to its <a href="#SkRect_left">left</a>, or if its <a href="#SkRect_bottom">bottom</a> is less than or equal to
its <a href="#SkRect_top">top</a>, it is considered empty.

<a href="#SkRect">SkRect</a> can be constructed from int values to avoid compiler warnings that
integer input cannot convert to <a href="undocumented#SkScalar">SkScalar</a> without loss of precision.

## MakeEmpty

<pre style="padding: 1em 1em 1em 1em;width: 62.5em; background-color: #f0f0f0">
static constexpr SkRect SK_WARN_UNUSED_RESULT MakeEmpty()
</pre>

Returns constructed <a href="#Rect">Rect</a> <a href="#SkRect_set">set</a> to (0, 0, 0, 0).
Many other rectangles are empty; if <a href="#SkRect_left">left</a> is equal to or greater than <a href="#SkRect_right">right</a>,
or if <a href="#SkRect_top">top</a> is equal to or greater than <a href="#SkRect_bottom">bottom</a>. Setting all members to zero
is a convenience, but does not designate a special empty rectangle.

### Return Value

bounds (0, 0, 0, 0)

### Example

<div><fiddle-embed name="2e262d0ac4b8ef51695e0525fc3ecdf6">

Passing integer values may generate a compiler warning since <a href="#Rect">Rect</a> cannot
represent 32-bit integers exactly. Use <a href="SkIRect_Reference#SkIRect">SkIRect</a> for an exact integer rectangle.

Offsets <a href="#Rect">Rect</a> by adding <a href="#SkRect_offset_2_delta">delta</a>.fX to <a href="#SkRect_fLeft">fLeft</a>, <a href="#SkRect_fRight">fRight</a>; and by adding <a href="#SkRect_offset_2_delta">delta</a>.fY to
<a href="#SkRect_fTop">fTop</a>, <a href="#SkRect_fBottom">fBottom</a>.

If <a href="#SkRect_offset_2_delta">delta</a>.fX is negative, moves <a href="#Rect">Rect</a> to the <a href="#SkRect_left">left</a>.
If <a href="#SkRect_offset_2_delta">delta</a>.fX is positive, moves <a href="#Rect">Rect</a> to the <a href="#SkRect_right">right</a>.
If <a href="#SkRect_offset_2_delta">delta</a>.fY is negative, moves <a href="#Rect">Rect</a> upward.
If <a href="#SkRect_offset_2_delta">delta</a>.fY is positive, moves <a href="#Rect">Rect</a> downward.

# <a name="Intersection"></a> Intersection
<a href="#Rect">Rects</a> <a href="#SkRect_intersect">intersect</a> when they enclose a common area. To <a href="#SkRect_intersect">intersect</a>, each of the pair
must describe area; <a href="#SkRect_fLeft">fLeft</a> is less than <a href="#SkRect_fRight">fRight</a>, and <a href="#SkRect_fTop">fTop</a> is less than <a href="#SkRect_fBottom">fBottom</a>;
empty() returns false. The intersection of <a href="#Rect">Rect</a> pair can be described by:

(max(a.fLeft, b.fLeft), max(a.fTop, b.fTop),
min(a.fRight, b.fRight), min(a.fBottom, b.fBottom)).

The intersection is only meaningful if the resulting <a href="#Rect">Rect</a> is not empty and
describes an area: <a href="#SkRect_fLeft">fLeft</a> is less than <a href="#SkRect_fRight">fRight</a>, and <a href="#SkRect_fTop">fTop</a> is less than <a href="#SkRect_fBottom">fBottom</a>.
