Struct GeoKeyDirectory 

pub struct GeoKeyDirectory {
    pub version: u16,
    pub major_revision: u16,
    pub minor_revision: u16,
    pub keys: Vec<GeoKey>,
}

Parsed GeoKey directory.

Fields

version: u16

major_revision: u16

minor_revision: u16

keys: Vec<GeoKey>

Implementations

impl GeoKeyDirectory

pub fn new() -> GeoKeyDirectory

Create an empty directory with default version (1.1.0).

pub fn parse( directory: &[u16], double_params: &[f64], ascii_params: &str, ) -> Option<GeoKeyDirectory>

Parse the GeoKey directory from the three GeoTIFF tags.

• directory: contents of tag 34735 (SHORT array)
• double_params: contents of tag 34736 (DOUBLE array), may be empty
• ascii_params: contents of tag 34737 (ASCII), may be empty

pub fn get(&self, id: u16) -> Option<&GeoKey>

Look up a GeoKey by ID.

pub fn get_short(&self, id: u16) -> Option<u16>

Get a short value for a key.

pub fn get_ascii(&self, id: u16) -> Option<&str>

Get an ASCII value for a key.

pub fn get_double(&self, id: u16) -> Option<&[f64]>

Get double value(s) for a key.

pub fn set(&mut self, id: u16, value: GeoKeyValue)

Insert or replace a GeoKey.

pub fn remove(&mut self, id: u16)

Remove a GeoKey by ID.

pub fn serialize(&self) -> (Vec<u16>, Vec<f64>, String)

Serialize the directory into the three TIFF tag payloads.

Returns (directory_shorts, double_params, ascii_params). Keys are sorted by ID per spec. Short values go inline (location=0), Double values reference the double_params array (location=34736), Ascii values reference the ascii_params string (location=34737).

Trait Implementations

impl Clone for GeoKeyDirectory
