Struct Affine 

pub struct Affine(pub [f64; 6]);

[x0, dx, rx, y0, ry, dy], as GDAL and vaster order them:

x = x0 + col * dx + row * rx
y = y0 + col * ry + row * dy

(col, row) are continuous index coordinates (0 is the outer edge of the first cell). Rotation and shear terms (rx, ry) are allowed.

Tuple Fields

0: [f64; 6]

Implementations

impl Affine

pub fn from_extent(extent: [f64; 4], dim: [usize; 2]) -> Self

From an extent [xmin, xmax, ymin, ymax] and dimension [ncol, nrow], north up (row 0 at ymax).

pub fn extent(&self, dim: [usize; 2]) -> [f64; 4]

The extent [xmin, xmax, ymin, ymax] covered by dim cells, for an axis-aligned transform.

pub fn forward(&self, col: f64, row: f64) -> (f64, f64)

pub fn inverse(&self) -> Option<Affine>

pub fn is_axis_aligned(&self) -> bool
