Crate reflow_pixel 

Pure-Rust pixel operations for Reflow image/video processing actors.

This crate is Wasm-safe — no system dependencies, no threads, no filesystem.

Features

• simd — Enables hand-tuned SIMD paths:
  • aarch64: NEON intrinsics for row_rgba_to_gray (8 pixels/iter)
  • wasm32: SIMD128 intrinsics for row_rgba_to_gray (4 pixels/iter) and row_brightness (4 pixels/iter)

Modules

• [format] — Pixel format descriptors (RGBA8, RGB8, Gray8, etc.)
• color — Color space conversions (RGB ↔ HSV, grayscale, brightness/contrast/saturation)
• blend — Alpha blending and compositing (Normal, Multiply, Screen, Overlay, Add)
• resize — Bilinear interpolation (full-image and streaming row-by-row)
• chroma — Chroma key removal (green/blue screen)
