Parameters:

Name	Type	Attributes	Default	Description
opts	Object			options Properties Name Type Attributes Default Description translatePercent ArrayXY <optional> [0,0] translates scale ArrayXY <optional> [1,1] scale percent rotate NumberArgument <optional> 0 degrees of rotation shear NumberArgument <optional> 0 degrees of shear
keepSize	BooleanArgument	<optional>	false	If true, the output image plane size will be fitted to the distorted image size, i.e. images rotated by 45deg will not be partially outside of the image plane. WARNING : not implemented yet

Examples

// Simple usage, Affine transform with scale change
ia.affine({scale: 1.2});

// Affine transform with rotation of 90° and random scale between 100% and 150%
ia.affine({scale: h.number(1, 1.5), rotate: 90});
