Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

width: u32

Columns.

height: u32

Rows.

corner_longitude_deg: f64

Longitude of the outer corner of pixel (0, 0) (its west edge when Δλ > 0), degrees.

corner_latitude_deg: f64

Latitude of the outer corner of pixel (0, 0) (its north edge when Δφ < 0), degrees.

pixel_longitude_deg: f64

Δλ: longitude change from one column to the next, degrees.

pixel_latitude_deg: f64

Δφ: latitude change from one row to the next, degrees; negative when north is up.

raster_type: RasterType

What the file’s tiepoint names; already applied to the corner above.

geographic_crs_epsg: u16

The geographic CRS’s EPSG code, one of NEAR_WGS84.

vertical_crs_epsg: Option<u16>

The vertical CRS’s EPSG code, if the file names one (a user-defined or private code, 32767 and above, is not one).

vertical_unit: VerticalUnit

The unit pixel values are in, after the scale and offset.

vertical_unit_stated: bool

Whether the file states that unit (by VerticalUnitsGeoKey, a vertical CRS this reader knows, or a unit type in GDAL’s GDAL_METADATA); false means meters were assumed.

scale: f64

The pixels’ scale: a raw value v stands for v·scale + offset in the vertical unit.

offset: f64

The pixels’ offset, in the vertical unit.

sample: SampleType

The pixels’ sample type.

nodata: Option<f64>

The nodata value, rounded to the sample type, if the file has one a sample can hold.

Implementations

impl RasterInfo

pub fn pixel_of(&self, latitude_deg: f64, longitude_deg: f64) -> Option<Pixel>

The pixel holding a point, by the module’s rule, or None if the point is off the raster. The longitude is tried as given and then 360° to either side, so a file on 0° to 360° reads a longitude given on −180° to 180°.

pub fn bounds(&self) -> Bounds

The raster’s edges.

pub fn meters(&self, value: f64) -> f64

A raw value as a height in meters: (v·scale + offset)·unit.

Trait Implementations

impl Clone for RasterInfo

fn clone(&self) -> RasterInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RasterInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RasterInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RasterInfo

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RasterInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
