v0.2.0

Release Notes: v0.2.0

Highlights

GPU Acceleration - This release introduces GPU-accelerated image processing using WebGPU
(wgpu), providing significant performance improvements for film negative conversion.

New Features

GPU Acceleration

• Added full GPU processing pipeline with automatic fallback to CPU when GPU is unavailable
• Implemented GPU shaders for:
  • Color inversion
  • Color matrix transformations
  • Tone curve application
  • Color space conversion
  • Histogram computation
• New --cpu flag to force CPU-only processing when needed
• GPU context management with buffer pooling for efficient memory usage

CLI Improvements

• Added JSON output support for analysis results (--json flag)
• New command options for base estimation configuration
• Improved output format flexibility

Documentation

• Updated README with detailed descriptions of inversion modes
• Enhanced CLI option documentation

Technical Changes

• New invers-core::gpu module with:
  • context.rs - GPU device and queue management
  • pipeline.rs - Processing pipeline orchestration
  • buffers.rs - GPU buffer management
  • WGSL shaders for all processing stages
• Added build_convert_options_full_with_gpu function for GPU-specific configuration
• Extended ConvertOptions model with GPU settings
