Struct GridTransform 

#[non_exhaustive]
pub struct GridTransform { /* private fields */ }

An affine integer lattice-coordinate transform: destination = matrix * source + translation.

The source and destination coordinates belong to the same LatticeKind. Pure D4/D6 symmetry transforms have zero translation; target-detector alignments use the same type with a board-frame translation. This type contains no image-space or pixel-space coordinates.

Implementations

impl GridTransform

pub const IDENTITY: Self

The identity transform for a square lattice.

Prefer Self::identity when the lattice family is dynamic. This constant exists for the workspace’s square-target result defaults.

pub const fn new( lattice: LatticeKind, matrix: [[i32; 2]; 2], translation: [i32; 2], ) -> Self

Construct a lattice transform from its family, row-major linear part, and destination-frame translation.

pub const fn identity(lattice: LatticeKind) -> Self

Construct the identity transform for lattice.

pub const fn lattice(self) -> LatticeKind

Lattice family of both the source and destination coordinates.

pub const fn matrix(self) -> [[i32; 2]; 2]

Row-major 2x2 integer linear part.

pub const fn translation(self) -> [i32; 2]

Destination-frame translation applied after the linear part.

pub const fn with_translation(self, translation: [i32; 2]) -> Self

Return this transform with a replacement destination-frame translation.

pub fn apply(self, coord: Coord) -> Coord

Apply this transform to a coordinate.

pub const fn determinant(self) -> i32

Determinant of the linear part.

pub fn inverse(self) -> Option<Self>

Invert this transform when its linear part is unimodular (determinant == ±1).

Returns None for a non-bijective integer transform. The inverse maps destination-frame coordinates back into the original source frame.
