AffineTransform class

AffineTransform uses a 3x3 matrix with an implied last row of [ 0 0 1 ] to transform source coordinates (x,y) into destination coordinates (x', y') according to: x' x = shear_y scale_y translate_y 1 [ 1 ] After transformation, x' = scale_x * x + shear_x * y + translate_x; y' = scale_y * y + shear_y * x + translate_y; This message is therefore composed of these six matrix elements.

Constructors

AffineTransform({double? scaleX, double? scaleY, double? shearX, double? shearY, double? translateX, double? translateY, String? unit})
