Module iron_shapes::transform[][src]

Expand description

Transforms are used to describe the location, rotation, scaling and mirroring of geometric shapes.

Structs

Transformation described by a mirroring at the x axis, then a rotation around the origin, then a scaling, then a translation. This transformation allows rotations by arbitrary angles.

Description of a transformation in the euclidean plane by a 2x2 matrix A. Transforming a point p is computed by the matrix product A*p.

Affine transformation represented as a 3x3 matrix like:

Transformation that consists only of a rotation by a multiple of 90 degrees around the origin (0, 0).

Describes a geometric transformation that consists of a optional mirroring along the x-axis followed by a rotation by a multiple of 90 degrees followed by a displacement.

Traits

Geometric transformation which preserves parallelism. Adds ‘shear’ to the SimilarityTransform.

Geometric transformation which preserves oriented angles and distances (i.e. translation).

Geometric transformation which preserves angles and distances (e.g. euclidean transform) but allows only rotations by a multiple of 90 degrees.

Geometric transformation which preserves angles and distances (e.g. euclidean transform).

Geometric transformation which preserves angles and ratios of distances. Adds resizing by integer numbers to the IsometricRTransform.

Geometric transformation which preserves angles and ratios of distances. Adds resizing to the IsometricTransform.

General geometric transformation.
