Implementations

impl Dataset

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

Open a dataset from a file path

pub fn path(&self) -> &Path

Get the file path

pub fn raster_size(&self) -> (usize, usize)

Get raster size (width, height)

pub fn width(&self) -> u64

Get raster width

pub fn height(&self) -> u64

Get raster height

pub fn raster_count(&self) -> usize

Get raster band count

pub fn data_type(&self) -> RasterDataType

Get the data type

pub fn projection(&self) -> Result<String, OxiGdalError>

Get projection (WKT string)

pub fn geotransform(&self) -> Result<[f64; 6], OxiGdalError>

Get geotransform as array

pub fn geo_transform_obj(&self) -> Option<&GeoTransform>

Get the GeoTransform

pub fn nodata(&self) -> NoDataValue

Get NoData value

pub fn tile_size(&self) -> Option<(u32, u32)>

Get tile size if tiled

pub fn overview_count(&self) -> usize

pub fn read_tile( &self, level: usize, tile_x: u32, tile_y: u32, ) -> Result<Vec<u8>, OxiGdalError>

Read a tile from the dataset

Arguments

• level - Overview level (0 = full resolution)

pub fn read_window( &self, x_offset: u64, y_offset: u64, x_size: u64, y_size: u64, ) -> Result<RasterBuffer, OxiGdalError>

Read a window of data from the dataset as RasterBuffer

Arguments

• x_offset - X offset in pixels
• y_offset - Y offset in pixels
• x_size - Width to read
• y_size - Height to read

pub fn get_pixel(&self, x: u64, y: u64) -> Result<f64, OxiGdalError>

Get pixel value at coordinates

pub fn rasterband(&self, _band: usize) -> Result<RasterBandInfo, OxiGdalError>

Get raster band info (for compatibility with old code)
