SkIRect holds four 32bit integer coordinates describing the upper and lower bounds of a rectangle.
SkIRect may be created from outer bounds or from position, width, and height. SkIRect 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.

inline 
Adjusts SkIRect by adding dL to fLeft, dT to fTop, dR to fRight, and dB to fBottom.
If dL is positive, narrows SkIRect on the left. If negative, widens it on the left. If dT is positive, shrinks SkIRect on the top. If negative, lengthens it on the top. If dR is positive, narrows SkIRect on the right. If negative, widens it on the right. If dB is positive, shrinks SkIRect on the bottom. If negative, lengthens it on the bottom.
The resulting SkIRect is not checked for validity. Thus, if the resulting SkIRect left is greater than right, the SkIRect will be considered empty. Call sort() after this call if that is not the desired behavior.

dT  offset added to fTop

Insets SkIRect by (dx,dy).
If dx is positive, makes SkIRect narrower. If dx is negative, makes SkIRect wider. If dy is positive, makes SkIRect shorter. If dy is negative, makes SkIRect taller.

inlinestatic 
Returns constructed SkIRect set to (0, 0, 0, 0).
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 is a convenience, but does not designate a special empty rectangle.

inline 
Returns SkIRect, inset by (dx, dy).
If dx is negative, SkIRect returned is wider. If dx is positive, SkIRect returned is narrower. If dy is negative, SkIRect returned is taller. If dy is positive, SkIRect returned is shorter.

dy  offset added to fTop and subtracted from fBottom 

inlinestatic 

inline 
Returns SkIRect offset by (dx, dy).
If dx is negative, SkIRect returned is moved to the left. If dx is positive, SkIRect returned is moved to the right. If dy is negative, SkIRect returned is moved upward. If dy is positive, SkIRect returned is moved downward.
dx  offset added to fLeft and fRight 
dy  offset added to fTop and fBottom 
Returns SkIRect offset by (offset.x(), offset.y()).
If offset.x() is negative, SkIRect returned is moved to the left. If offset.x() is positive, SkIRect returned is moved to the right. If offset.y() is negative, SkIRect returned is moved upward. If offset.y() is positive, SkIRect returned is moved downward.

Offsets SkIRect by adding dx to fLeft, fRight; and by adding dy to fTop, fBottom.
If dx is negative, moves SkIRect returned to the left. If dx is positive, moves SkIRect returned to the right. If dy is negative, moves SkIRect returned upward. If dy is positive, moves SkIRect returned downward.

Offsets SkIRect by adding delta.fX to fLeft, fRight; and by adding delta.fY to fTop, fBottom.
If delta.fX is negative, moves SkIRect returned to the left. If delta.fX is positive, moves SkIRect returned to the right. If delta.fY is negative, moves SkIRect returned upward. If delta.fY is positive, moves SkIRect returned downward.
