Struct MultibandPipeline 

pub struct MultibandPipeline<T: Pod> { /* private fields */ }

Multi-band raster compute pipeline.

Implementations

impl<T: Pod + Zeroable> MultibandPipeline<T>

pub fn new(context: &GpuContext, raster: &GpuRasterBuffer<T>) -> GpuResult<Self>

Create a new multiband pipeline.

pub fn num_bands(&self) -> usize

Get the number of bands.

pub fn band(&self, index: usize) -> Option<&ComputePipeline<T>>

Get a specific band pipeline.

pub fn map<F>(self, f: F) -> GpuResult<Self>

where F: FnMut(ComputePipeline<T>) -> GpuResult<ComputePipeline<T>>,

Apply operation to all bands.

pub fn ndvi(self) -> GpuResult<ComputePipeline<T>>

Compute NDVI (Normalized Difference Vegetation Index).

NDVI = (NIR - Red) / (NIR + Red)

Errors

Returns an error if the raster doesn’t have at least 4 bands (R,G,B,NIR).

pub fn finish(self) -> Vec<GpuBuffer<T>>

Finish and get all band buffers.

pub async fn read_all(self) -> GpuResult<Vec<Vec<T>>>

Read all bands to CPU memory.
