Struct GeoTiffReader 

pub struct GeoTiffReader {
    pub width: usize,
    pub height: usize,
    pub bands: usize,
    pub transform: [f64; 6],
    /* private fields */
}

A minimal GeoTIFF-style raster reader that holds image geometry and georeferencing metadata.

The affine transform follows the standard 6-parameter GDAL convention: [x_origin, pixel_width, row_rotation, y_origin, col_rotation, pixel_height] where pixel_height is typically negative (top-left origin).

Fields

width: usize

Raster width in pixels.

height: usize

Raster height in pixels.

bands: usize

Number of spectral or data bands.

transform: [f64; 6]

Six-element affine geotransform (GDAL order).

Implementations

impl GeoTiffReader

pub fn new( width: usize, height: usize, bands: usize, transform: [f64; 6], data: Vec<Vec<f64>>, ) -> Self

Construct a new GeoTiffReader with explicit dimensions and transform.

pub fn pixel_to_world(&self, px: usize, py: usize) -> [f64; 2]

Convert pixel coordinates (px, py) to world (lon, lat) coordinates using the stored affine transform.

pub fn world_to_pixel(&self, lon: f64, lat: f64) -> (usize, usize)

Convert world (lon, lat) coordinates to pixel coordinates using the inverse of the stored affine transform.

pub fn read_band(&self, band: usize) -> Vec<f64>

Return a clone of band band data (0-indexed).

Returns an empty vector if band >= self.bands.

pub fn elevation_at(&self, lon: f64, lat: f64) -> f64

Return the elevation (first-band value) at world coordinate (lon, lat).

pub fn bounding_box(&self) -> [f64; 4]

Return the bounding box [min_lon, min_lat, max_lon, max_lat].

Trait Implementations
