The DOMPointInit
dictionary's x
property is used to specify the x component of a point in 2D or 3D space when either creating or serializing a DOMPoint
or DOMPointReadOnly
.
In general, positive values x
mean to the right, and negative values of x
means to the left, assuming that transforms have not altered the orientation of the axes.
Syntax
var DOMPointInit = { x: xPos }; DOMPointInit.x = xPos; var xPos = DOMPointInit.x;
Value
A double-precision floating-point value indicating the point's x coordinate. This value is unrestricted, meaning that it is allowed to be infinite or invalid (that is, its value may be NaN
or Β±Infinity
).
If this property is missing when the DOMPointInit
object is passed into fromPoint()
, the value is assumed to be 0 by default.
DOMPointInit
is used as an input when calling either DOMPointReadOnly.fromPoint()
or DOMPoint.fromPoint()
, and is returned by the DOMPointReadOnly.toJSON()
and DOMPoint.toJSON()
methods.
