NAME

Intertangle::Taffeta::Transform::Affine2D - A 2D affine transform

VERSION

version 0.001

EXTENDS

ATTRIBUTES

matrix

The Intertangle::Yarn::Graphene::Matrix matrix representing the affine transform.

This matrix is the identity matrix by default.

cairo_matrix

A Cairo::Matrix representation of the affine transform.

svg_transform

A Str representation of the affine transform that can be used with transform attribute for SVG elements such as <g> or graphics elements.

See https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/transform.

METHODS

BUILDARGS

matrix_abcdef

   [
       a c 0 0
       b d 0 0
       0 0 1 0
       e f 0 1
   ]

matrix_xy

  [
     xx yx  0  0
     xy yy  0  0
      0  0  1  0
     x0 y0  0  1
  ]

If keys are not given for either approach, the default values for the identity matrix are used:

  a, d : 1
  b, c : 0
  e, f : 0

  xx, yy : 1
  yx, xy : 0
  x0, y0 : 0

compose

Compose the transform with another transform by using matrix multiplication: (this x that).

compose_premultiply

Compose the transform with another transform by using matrix multiplication: (that x this).

apply_to_bounds

Apply the transformation to a Intertangle::Yarn::Graphene::Rect.

apply_to_point

Apply the transformation to a Intertangle::Yarn::Graphene::Point.

apply_to_vec3

Apply the transformation to a Intertangle::Yarn::Graphene::Vec3.
