Struct CoordinateGrid 

pub struct CoordinateGrid {
    pub latitude: Option<Array2<f64>>,
    pub longitude: Option<Array2<f64>>,
    pub latitude_axis: Option<Vec<f64>>,
    pub longitude_axis: Option<Vec<f64>>,
}

Fields

latitude: Option<Array2<f64>>

Latitude at each displayed source cell for a curvilinear grid.

longitude: Option<Array2<f64>>

Longitude at each displayed source cell for a curvilinear grid.

latitude_axis: Option<Vec<f64>>

Latitude values for a regular grid, indexed by source row.

Keeping regular coordinates as axes avoids expanding two small 1-D vectors into full-size f64 planes for large rasters.

longitude_axis: Option<Vec<f64>>

Longitude values for a regular grid, indexed by source column.

Implementations

impl CoordinateGrid

pub fn is_empty(&self) -> bool

pub fn shape(&self) -> Option<(usize, usize)>

pub fn latitude_at(&self, row: usize, col: usize) -> Option<f64>

pub fn longitude_at(&self, row: usize, col: usize) -> Option<f64>

pub fn latitude_increases_with_source_row(&self) -> bool

Return whether source rows run from south to north.

Raster images are displayed north-up, so this is the condition under which a renderer must reverse the source row order. A missing or non-monotonic coordinate does not imply an order and keeps the source layout unchanged.

pub fn source_row_for_display_row( &self, display_row: usize, display_rows: usize, source_rows: usize, ) -> usize

Map a displayed north-to-south row to its source row.

pub fn source_row_for_display_row_with_flip( &self, display_row: usize, display_rows: usize, source_rows: usize, flip_rows: bool, ) -> usize

pub fn display_row_for_source_row( &self, source_row: usize, source_rows: usize, display_rows: usize, ) -> usize

Map a source row to its north-to-south displayed row.

pub fn display_row_for_source_row_with_flip( &self, source_row: usize, source_rows: usize, display_rows: usize, flip_rows: bool, ) -> usize

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for CoordinateGrid

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

Formats the value using the given formatter.
