Fixed issue with DcmSwift handing 12-bit data. Refactors DicomImage to provide a unified image(forFrame:wwl:inverted:) method for both macOS and iOS, supporting window/level adjustment and inversion for monochrome images. Adds a new renderFrame method for accurate grayscale rendering, handles both compressed and uncompressed images, and improves code clarity and maintainability. Also updates PhotometricInterpretation to be a String-backed enum.

Optimize pixel processing and translate comments

Introduces OPTIMIZATION_REVIEW.md summarizing integrated and missing optimizations in DcmSwift. Refactors DicomTool.swift to remove dependency on DicomServiceProtocol, implements direct DICOM decoding and display logic, improves window/level handling, and adds utility methods for pixel data extraction and validation.

Replaces DCMImgView with DicomPixelView and migrates all image rendering logic into DcmSwift/Graphics, introducing Metal-based GPU acceleration (MetalAccelerator, MetalShaders, Shaders.metal). Removes legacy References files, updates documentation and usage examples, and adds PixelService. Updates networking and data handling for improved performance and reliability. Package.swift now includes Metal shader resources.

Optimize Metal window-level pipeline for better parallelism

Refactored C-FIND request handling to send command and dataset in separate PDUs, and updated response parsing for fragmented datasets. Fixed AE title padding to use spaces instead of nulls. Enhanced UserInfo PDU construction to include Implementation UID and Version. Added test scripts for C-FIND and C-ECHO operations.

feat: stream DICOM pixel data fragments

Replaces async/await task groups with DispatchQueue.concurrentPerform for concurrent window/level and LUT application, improving performance and compatibility. Updates DicomPixelView to use background tasks for 8-bit window/level processing, with fallback for older OS versions. Refines Accelerate usage for type conversion, and updates Metal shader and dispatch logic to support variable output components and more robust threadgroup handling.

Refactors CFindRQ to send both the command and dataset together in a single P-DATA-TF PDU, updating CommandDataSetType handling per DICOM PS 3.7. Adds a unit test to verify correct PDV packing and CommandDataSetType values.

Enhances DIMSE C-GET and C-STORE handling to support correct PDV packing, multi-fragment C-STORE sub-operations, and robust file saving with proper Part-10 meta headers. Adds support for more DICOM modalities, improves memory management for large files, and fixes presentation context selection for responses. Includes new tests for C-GET DIMSE packing and DataTF status handling, and improves QIDOClient modality query logic.

The README has been rewritten to provide a comprehensive overview of DcmSwift, including GPU-accelerated image processing, full networking (DIMSE and DICOMweb), performance optimizations, and production readiness. It now details key features, architecture, benchmarks, main APIs, integration steps, and command-line tool usage, offering clearer guidance for developers and highlighting the library's capabilities and requirements.
