Struct h3ron_ndarray::transform::Transform

pub struct Transform { /* fields omitted */ }

affine geotransfrom

ported from affine library (used by rasterio) https://github.com/sgillies/affine/blob/master/affine/init.py

a, b, c, d, e, f : float Coefficients of an augmented affine transformation matrix | x' | | a b c | | x | | y' | = | d e f | | y | | 1 | | 0 0 1 | | 1 |

a, b, and c are the elements of the first row of the matrix. d, e, and f are the elements of the second row.

Implementations

impl Transform

pub fn new(a: f64, b: f64, c: f64, d: f64, e: f64, f: f64) -> Self

pub fn from_rasterio(transform: &[f64; 6]) -> Self

create from an f64 slice in the ordering used by rasterio

pub fn from_gdal(transform: &[f64; 6]) -> Self

create from an f64 slice in the ordering used by gdal

pub fn determinant(&self) -> f64

The determinant of the transform matrix

pub fn is_degenerate(&self) -> bool

True if this transform is degenerate.

Which means that it will collapse a shape to an effective area of zero. Degenerate transforms cannot be inverted.

pub fn invert(&self) -> Result<Self, Error>

Trait Implementations

impl Clone for Transform

pub fn clone(&self) -> Transform

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Transform

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Mul<&'_ Coordinate<f64>> for &Transform

apply the transformation to a coordinate

type Output = Coordinate<f64>

The resulting type after applying the * operator.

pub fn mul(self, rhs: &Coordinate<f64>) -> Self::Output

Performs the * operation.

impl Mul<&'_ Rect<f64>> for &Transform

apply the transformation to a rect

type Output = Rect<f64>

The resulting type after applying the * operator.

pub fn mul(self, rhs: &Rect<f64>) -> Self::Output

Performs the * operation.

impl PartialEq<Transform> for Transform

pub fn eq(&self, other: &Transform) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &Transform) -> bool

This method tests for !=.
