Struct RasterView 

pub struct RasterView<'a, T: Sample> { /* private fields */ }

Borrowed, dimension-checked view of one pixel-interleaved raster band.

Implementations

impl<'a, T: Sample> RasterView<'a, T>

pub fn new(width: u32, height: u32, depth: u32, data: &'a [T]) -> Result<Self>

Creates a raster view.

Errors

Returns an error when depth is zero, dimensions overflow, or data has a different length than width * height * depth.

pub fn width(self) -> u32

Returns the raster width in pixels.

pub fn height(self) -> u32

Returns the raster height in pixels.

pub fn depth(self) -> u32

Returns the number of samples per pixel.

pub fn data(self) -> &'a [T]

Returns the underlying pixel-interleaved sample slice.

pub fn data_type(self) -> DataType

Returns the encoded sample type.

pub fn pixel_count(self) -> Result<usize>

Returns width * height using checked arithmetic.

pub fn sample_count(self) -> Result<usize>

Returns the total sample count using checked arithmetic.

pub fn sample(self, pixel: usize, dim: usize) -> T

Returns one sample by flat pixel index and depth index.

Panics

Panics if pixel or dim is outside this view.
