Struct InMemoryRasterSource 

pub struct InMemoryRasterSource { /* private fields */ }

In-memory raster source backed by a Vec<f32> for testing and small workloads.

This implementation stores raster data in a flat row-major Vec<f32> and supports efficient sub-window reads with zero-padding for out-of-bounds pixels.

Implementations

impl InMemoryRasterSource

pub fn new(data: Vec<f32>, width: usize, height: usize) -> Self

Creates a new in-memory raster source.

Panics

Panics if data.len() != width * height.

pub fn data(&self) -> &[f32]

Returns a reference to the underlying data slice.

Trait Implementations

impl RasterSource for InMemoryRasterSource

fn width(&self) -> usize

Total width of the raster in pixels.

fn height(&self) -> usize

Total height of the raster in pixels.

fn read_window( &self, x: usize, y: usize, w: usize, h: usize, ) -> Result<Vec<f32>, RasterError>

Read a rectangular window of pixels into a Vec<f32>, row-major order.
