Struct GeoTransform 

Source 
pub struct GeoTransform(pub Affine);
Expand description

Newtype wrapping raffine::Affine as a GeoTransform.

from_gdal(&[c, a, b, f, d, e]) accepts the same 6-tuple format used by GDAL and rasterio. Forward maps pixel → world; inverse() maps world → pixel.

Implementations§

Source§

impl GeoTransform

Source

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

Construct from GDAL coefficients [x_origin, x_scale, x_skew, y_origin, y_skew, y_scale].

Source

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

Transform pixel coordinates, with integer coordinates at pixel corners.

Source

pub fn translated(&self, col_off: f64, row_off: f64) -> Self

Shift the pixel-space origin by the given column and row offsets.

Source

pub fn scaled(&self, sx: f64, sy: f64) -> Self

Scale pixel-space column and row coordinates before mapping to the CRS.

Source

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

Return the world-to-pixel transform, or None for a singular transform.

Source

pub fn window_for_bbox(&self, bbox: &Bbox) -> Option<(i64, i64, u64, u64)>

Pixel window covering the bbox. Returns (col_off, row_off, width, height), or None when the transform is not invertible or the pixel endpoints cannot be represented as i64.
