From e25a7d7552d2e0ac1212ffddcc269809d48810d4 Mon Sep 17 00:00:00 2001 From: myyc Date: Wed, 15 Apr 2026 18:45:05 +0200 Subject: [PATCH] Refactor ImageState + add highlight-recovery, fix exposure, smooth histogram MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Large cleanup branch that rewrites the RAW-processing glue and fixes several rendering issues uncovered along the way. ## Cleanup & dedup - Delete dead code: `lib/services/isolate_processor.dart`, `lib/ffi/raw/raw_processor.dart`, and the adjustment math in `lib/services/image_processor.dart` (nothing called it). - Consolidate the native RAW build: `scripts/build_test_libs.sh`, `dev.myyc.aks.yaml`, and `linux/CMakeLists.txt` all compile `raw_processor_wrapper.c` which includes `lib/ffi/raw/raw_processor_common.c`. Previously there were three drifting copies of the same source. - Move `RawPixelData` to its own file; extract `applyCropToImage` into `crop_service.dart`; extract `generateCurveLookupTable` into `processors/curve_lut.dart` (was copy-pasted 3x). ## ImageState refactor - Slim `lib/models/image_state.dart` from 546 → ~370 LOC. - New `ImageCacheBundle` centralises disposal of the 4 `ui.Image` refs. - New `ProcessingPipeline` owns pixel buffers, timers, processor dispatch; fixes the line-406 unawaited-timer leak. ## Highlight recovery - Hardcode libraw `params.highlight = 2` (blend) so the one-channel 255 pile-up (sky / window highlights) is redistributed instead of clipped. Plumbing supports clip/blend/reconstruct via `HighlightMode` enum; a settings panel can expose the selector later — see CLAUDE.md. - Compensate blend's systematic darkening with libraw's exposure-correction feature: `exp_shift = 2.0` (+1.0 EV) with `exp_preser = 1.0` so highlights are compressed rather than re-clipped. Lands blend within -15%/+7% of clip's mean brightness across 5 test fixtures, with zero re-introduced 255-pile-up. ## Linear-light exposure - `generateExposureLUT` and the Vulkan shader's `applyExposure` both previously did `byte * 2^EV` on sRGB-encoded values, massively over- amplifying midtones (at +1 EV, sRGB 128 → 256 clipped instead of ~179). - Both paths now sRGB-decode → multiply by 2^EV → sRGB-encode. CPU and GPU outputs agree to within 1 LSB on a real 24MP RAW across five EV values (-1, -0.5, 0, +0.5, +1). ## Histogram smoothing - Apply a 5-tap binomial blur twice (σ≈1.4) to the 256-bin counts before painting, matching Lightroom's display. Eliminates visible per-bin quantisation jitter and tapers legitimate spikes at 0/255. - 2D sampling stride is now `sqrt(total/target)` instead of `total/target`, so a 24MP image actually samples ~50k pixels (was ~96). ## Tests & lints - 96 tests green (66 unit + 30 native), up from 23. - New: `curve_lut_test`, `optimized_processor_test`, `edit_pipeline_test` (JSON roundtrip), `image_cache_bundle_test`, `processing_pipeline_test` (line-406 regression), `image_state_test`, `exposure_precision_test` (CPU ≡ Vulkan across 5 EVs), `fixtures_histogram_test` (blend regression guard on 5 real fixtures). - `analysis_options.yaml`: excludes generated FFI bindings, enables unused_* lints, cleans up 14 pre-existing dead imports/variables. - Test fixtures `test_image_{1,2,3,4}.{arw,raf}` gitignored — they're populated from local photo libraries and tests skip gracefully when absent. ## Numbers - 38 files changed, +544 / -2282 LOC net.
