Crate singe_npp 

Safe NVIDIA Performance Primitives wrappers for image and signal APIs.

This crate wraps NPP version queries, stream contexts, image and signal device memory, image processing pipelines, signal processing pipelines, typed image views, channel layouts, sizes, rectangles, and temporary workspaces.

Example

use singe_cuda::context::Context;
use singe_npp::{
    C3, ImagePipeline, ImageView, StreamContext, Workspace,
    types::{ComparisonOperation, InterpolationMode, Size},
};

let ctx = Context::create()?;
let stream = ctx.create_stream()?;
let stream_context = StreamContext::create(&stream)?;
let mut workspace = Workspace::create();

let device_memory = todo!();
let size = Size::new(640, 480);
let source = ImageView::<u8, C3>::from_memory(&device_memory, size)?;

let output = ImagePipeline::from_view(&stream_context, &mut workspace, source)
    .resize(Size::new(256, 256), InterpolationMode::Lanczos)?
    .rgb_to_gray()?
    .threshold(128, ComparisonOperation::Less)?
    .filter_sharpen()?
    .finish()?;
let image = output.copy_to_host_vec()?;

println!("NPP version: {:?}", singe_npp::version()?);
