The scale3dSelf() method of the DOMMatrix interface is a mutable transformation method that modifies a matrix by applying a specified scaling factor to all three axes, centered on the given origin, with a default origin of (0, 0, 0), returning the 3D-scaled matrix.
To 3D-scale a matrix without mutating it, see DOMMatrixReadOnly.scale3d(), which creates a new scaled matrix while leaving the original unchanged.
scale3dSelf()
scale3dSelf(scale)
scale3dSelf(scale, originX)
scale3dSelf(scale, originX, originY)
scale3dSelf(scale, originX, originY, originZ)
scale
A multiplier; the scale value. If no scale is supplied, this defaults to 1. If scale is not 1, the is2D property of the current matrix is set to false.
originX Optional
An x-coordinate for the origin of the transformation. If no origin is supplied, this defaults to 0.
originY Optional
A y-coordinate for the origin of the transformation. If no origin is supplied, this defaults to 0.
originZ Optional
A z-coordinate for the origin of the transformation. If no origin is supplied, this defaults to 0.
Returns itself; a DOMMatrix.
