oidn-wgpu 2.4.1

//! # oidn-wgpu
//!
//! [Intel Open Image Denoise](https://www.openimagedenoise.org) (OIDN) integration for [wgpu](https://docs.rs/wgpu).
//! Denoise path-traced or ray-traced images produced on the GPU by copying to CPU, running OIDN, and copying back.
//!
//! This crate targets **OIDN 2.4.x** and **wgpu 27**. It does not depend on `oidn-rs`.
//!
//! ## Setup
//!
//! Build and install OIDN 2.4.x (e.g. from <https://github.com/OpenImageDenoise/oidn>), then either:
//!
//! - Set **`OIDN_DIR`** to the install directory (containing `include/` and `lib/`), or
//! - Use **pkg-config** (Linux/macOS) with `OpenImageDenoise` installed.
//!
//! ## Example: denoise a wgpu texture
//!
//! ```ignore
//! # use std::error::Error;
//! # fn main() -> Result<(), Box<dyn Error>> {
//! use oidn_wgpu::{OidnDevice, denoise_texture, DenoiseTextureFormat, DenoiseOptions};
//!
//! let oidn = OidnDevice::new()?;
//! let format = DenoiseTextureFormat::Rgba16Float;
//! denoise_texture(
//!     &oidn,
//!     &wgpu_device,
//!     &wgpu_queue,
//!     &input_texture,
//!     &output_texture,
//!     format,
//!     &DenoiseOptions::default(), // or set quality, hdr, srgb, input_scale
//! )?;
//! # Ok(())
//! # }
//! ```
//!
//! ## Example: denoise CPU buffers (no wgpu)
//!
//! ```ignore
//! # use std::error::Error;
//! # fn main() -> Result<(), Box<dyn Error>> {
//! use oidn_wgpu::{OidnDevice, RtFilter};
//!
//! let device = OidnDevice::new()?;
//! let mut filter = RtFilter::new(&device)?;
//! filter.set_dimensions(width, height).set_hdr(true);
//! filter.execute_in_place(&mut color_rgb_f32)?;
//! # Ok(())
//! # }
//! ```
