< a href = '#SkIRect' > SkIRect< / a > holds four 32-bit integer coordinates describing the upper and
lower bounds of a rectangle. < a href = '#SkIRect' > SkIRect< / a > may be created from outer bounds or
from position, width, and height. < a href = '#SkIRect' > SkIRect< / a > describes an area; if its right
is less than or equal to its left, or if its bottom is less than or equal to
its top, it is considered empty.

Many other rectangles are empty; if left is equal to or greater than right,
or if top is equal to or greater than bottom. Setting all members to zero
2017-10-09 18:07:42 +00:00
is a convenience, but does not designate a special empty rectangle.
### Return Value

or if top is equal to or greater than bottom. Setting all members to zero
2017-10-09 18:07:42 +00:00
is a convenience, but does not designate a special empty rectangle.

2018-05-16 11:07:07 +00:00
< 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 > ;
empty() returns false. The intersection of < a href = '#IRect' > IRect< / a > pair can be described by:
2018-01-26 17:56:22 +00:00
2018-06-27 15:00:21 +00:00
(max(a.< a href = '#SkIRect_fLeft' > fLeft< / a > , b.< a href = '#SkIRect_fLeft' > fLeft< / a > ), max(a.< a href = '#SkIRect_fTop' > fTop< / a > , b.< a href = '#SkIRect_fTop' > fTop< / a > ),
min(a.< a href = '#SkIRect_fRight' > fRight< / a > , b.< a href = '#SkIRect_fRight' > fRight< / a > ), min(a.< a href = '#SkIRect_fBottom' > fBottom< / a > , b.< a href = '#SkIRect_fBottom' > fBottom< / a > ))
2018-03-05 18:26:16 +00:00
.
2018-01-26 17:56:22 +00:00
2018-05-16 11:07:07 +00:00
The intersection is only meaningful if the resulting < a href = '#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 > .

void < a href = '#SkIRect_adjust' > adjust< / a > (int32_t dL, int32_t dT, int32_t dR, int32_t dB)
< / pre >
Adjusts < a href = '#IRect' > IRect< / a > by adding < a href = '#SkIRect_adjust_dL' > dL< / a > to < a href = '#SkIRect_fLeft' > fLeft< / a > , < a href = '#SkIRect_adjust_dT' > dT< / a > to < a href = '#SkIRect_fTop' > fTop< / a > , < a href = '#SkIRect_adjust_dR' > dR< / a > to < a href = '#SkIRect_fRight' > fRight< / a > , and < a href = '#SkIRect_adjust_dB' > dB< / a > to < a href = '#SkIRect_fBottom' > fBottom< / a > .
If < a href = '#SkIRect_adjust_dL' > dL< / a > is positive, narrows < a href = '#IRect' > IRect< / a > on the left. If negative, widens it on the left.
If < a href = '#SkIRect_adjust_dT' > dT< / a > is positive, shrinks < a href = '#IRect' > IRect< / a > on the top. If negative, lengthens it on the top.
If < a href = '#SkIRect_adjust_dR' > dR< / a > is positive, narrows < a href = '#IRect' > IRect< / a > on the right. If negative, widens it on the right.
If < a href = '#SkIRect_adjust_dB' > dB< / a > is positive, shrinks < a href = '#IRect' > IRect< / a > on the bottom. If negative, lengthens it on the bottom.
The resulting < a href = '#IRect' > IRect< / a > is not checked for validity. Thus, if the resulting < a href = '#IRect' > IRect< / a > left is
greater than right, the < a href = '#IRect' > IRect< / a > will be considered empty. Call < a href = '#SkIRect_sort' > sort< / a > after this call
if that is not the desired behavior.
