Contexte
Le package extrait la preview JPEG mais n'exposait pas les métadonnées EXIF du RAW. Le parseur TIFF (
TiffReader/IfdEntry) lit déjà les IFD génériquement et connaîtExifIfdPointer— l'infra était là.Changements
RawMetadata(nouveau) : value object nullable —dateTimeOriginal,fNumber,exposureTime,iso,focalLength,lensModel,cameraMake,cameraModel+isEmpty().ExtractedPreview: nouveau paramètre optionnel?RawMetadata $metadata = null— non-breaking (compatible 1.1).TiffReader: préserve numérateur ET dénominateur des rationnels (avant : numérateur seul, insuffisant pour f-number/vitesse/focale).IfdEntry::rational()/rationalPair().TiffTag: 6 tags EXIF déclarés (ExposureTime, FNumber, IsoSpeedRatings, DateTimeOriginal, FocalLength, LensModel).TiffPreviewParser: lit Make/Model (IFD0) + suitExifIfdPointer→ EXIF IFD → mappe les réglages ; formate la vitesse en fraction (« 1/250 »).metadatadans le README etdocs/index.md.Portée
TIFF-based (CR2/NEF/ARW/DNG) via
ExifIfdPointer. CR3 (ISO-BMFF) : preview OK,metadata=nullpour l'instant (dégradation gracieuse). Tout est nullable.Tests
185 tests, 303 assertions (174 existants intacts + 11 nouveaux) :
IfdEntryrationnel,RawMetadata, et un test bout-en-bout sur TIFF synthétique avec sous-IFD EXIF (f/2.8, 1/250, ISO 400, 50 mm, objectif, date, appareil).composer validate --strictOK ; aucun Symfony hors bridge.Suite
Release cible 1.2.0. Consommé ensuite par HomeCloud (require ^1.2) pour le « pack photographe ».
