flutter_bicubic_resize 1.2.3

Fastest image resize, crop and compress for Flutter. 3-4x faster than other libraries. Native C code, consistent results on iOS/Android.

Changelog

1.2.3 - 2025-12-18

Added

• Format detection and validation - library now handles unsupported formats
  • ImageFormat enum (jpeg, png) for supported formats
  • UnsupportedImageFormatException - thrown for unsupported formats (HEIC, WebP, GIF, etc.)
  • BicubicResizer.detectFormat(bytes) - detect image format from bytes
  • BicubicResizer.resize(bytes: ...) - generic resize with auto-detection, throws exception for unsupported formats

1.2.2 - 2025-12-18

Added

• Crop anchor positions (CropAnchor) - crop from any position, not just center
  • center (default), topLeft, topCenter, topRight, centerLeft, centerRight, bottomLeft, bottomCenter, bottomRight
• Crop aspect ratio modes (CropAspectRatio) - control crop shape
  • square (default) - 1:1 aspect ratio
  • original - keep original image proportions
  • custom - use custom aspect ratio with aspectRatioWidth/aspectRatioHeight
• Edge handling modes (EdgeMode) - control how pixels outside bounds are handled
  • clamp (default) - repeat edge pixels
  • wrap - tile/repeat image
  • reflect - mirror reflection at edges
  • zero - black/transparent pixels outside
• JPEG EXIF control (applyExifOrientation) - option to disable EXIF orientation correction
• PNG compression control (compressionLevel) - adjust compression 0-9 (default: 6)

Changed

• All new parameters are optional with backward-compatible defaults
• Updated API documentation with comprehensive examples
• Expanded README with new features and usage examples

1.2.1 - 2025-12-14

Fixed

• iOS release build crash - Fixed FFI symbol stripping issue that caused "symbol not found" errors in release/archive builds
• Added proper Xcode build settings to prevent symbol stripping (STRIP_STYLE=non-global)
• Added symbol retention mechanism in Swift plugin to ensure C functions are linked

1.2.0 - 2025-12-14

Added

• EXIF orientation support for JPEG images - photos from mobile cameras now display correctly
• Automatic rotation/flip based on EXIF metadata (supports all 8 orientation values)

Changed

• Breaking: Crop now produces 1:1 aspect ratio (square) instead of proportional crop
  • crop: 1.0 on 1920x1080 image now crops to 1080x1080 (not 1920x1080)
  • This prevents stretching when resizing to square output (e.g., 224x224)
• Updated README with new features documentation

1.1.0 - 2025-12-12

Added

• Optional center crop parameter (crop) for all resize methods
• Crop value range: 0.0-1.0 (1.0 = no crop, 0.5 = center 50%)
