Implementations

impl GeoTiffFile

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self>

pub fn open_with_options<P: AsRef<Path>>( path: P, options: GeoTiffOpenOptions, ) -> Result<Self>

Open a GeoTIFF file from disk with explicit TIFF decoder options.

pub fn from_bytes(data: Vec<u8>) -> Result<Self>

Open a GeoTIFF from an owned byte buffer.

pub fn from_bytes_with_options( data: Vec<u8>, options: GeoTiffOpenOptions, ) -> Result<Self>

Open a GeoTIFF from bytes with explicit TIFF decoder options.
