In wk: Lightweight Well-Known Geometry Parsing

Affine transformer

Description

Affine transformer

Usage

wk_trans_affine(trans_matrix)

wk_affine_identity()

wk_affine_rotate(rotation_deg)

wk_affine_scale(scale_x = 1, scale_y = 1)

wk_affine_translate(dx = 0, dy = 0)

wk_affine_fit(src, dst)

wk_affine_rescale(rct_in, rct_out)

wk_affine_compose(...)

wk_affine_invert(x)

Arguments

trans_matrix	A 3x3 transformation matrix
rotation_deg	A rotation to apply in degrees counterclockwise.
scale_x, scale_y	Scale factor to apply in the x and y directions, respectively
dx, dy	Coordinate offsets in the x and y direction
src, dst	Point vectors of control points used to estimate the affine mapping (using base::qr.solve()).
rct_in, rct_out	The input and output bounds
...	Zero or more transforms in the order they should be applied.
x	A wk_trans_affine()
