pixer 0.0.10

High-performance Dart image manipulation backed by Rust FFI for resizing, cropping, encoding, and thumbnail generation in apps and tools.

0.0.10

• Fixed zero blur changing pixels and rejected subnormal blur values before they can panic in Rust.

• Preserved alpha and bit depth in grayscale conversion and prevented extreme brightness offsets from overflowing.

• Accounted for actual native pixel-buffer bytes, including 16-bit and floating-point images.

• Added native/WASM ABI version checks and compile-time WASM layout checks. Rebuild binaries for this package revision.

• Added a minimal Flutter showcase for Android, iOS, Linux, macOS, Windows, and WebAssembly.

• Added browser support backed by the Rust engine compiled to WebAssembly.

• Added Pixer.initialize() for loading the WebAssembly module on web.

• Shared image validation, batching, encoder configuration, and error mapping across native and web backends.

• Encoding now belongs to the image backend; use Pixer.encode(encoder) instead of the FFI-only PixerEncoder.encode(handle) helper.

• Breaking: Renamed the native encoding symbols to pixer_encode, pixer_encode_jpeg, and pixer_batch_encode; the JPEG function no longer takes a redundant format argument.

0.0.9

• Fixed the workspace benchmark package path so analysis and publish validation run successfully.
• Added lazy operation batches with toImage(), encode(), and saveToFile() terminals.

0.0.8

• Provide example and improve pubdev points.

0.0.7

• Added externalSize to the NativeFinalizer, which significantly improves Garbage Collection performance.

0.0.6

• Breaking: Merged Pixer.encodeWith(PixerEncoder) into Pixer.encode(PixerEncoder); the old encode(ImageFormatEnum) overload is gone. Use image.encode(const PixerPngEncoder()) etc.
• Breaking: Renamed ColorType.l / ColorType.la to ColorType.luminance / ColorType.luminanceAlpha. ColorType.fromValue now throws ArgumentError on unknown codes instead of defaulting to rgba.
• Breaking: Removed unused LoadException (load failures already throw specific exceptions).
• Fixed: Pixer.contrast docs: 0.0 is the neutral value (not 1.0).
• Docs: Clarified Pixer.resize semantics (fits within the bounds; use resizeExact for exact sizes).
• Docs: Documented Pixer.brightness clamping and practical range.
• Docs: Added doc comments to all generated FilterTypeEnum, ImageFormatEnum, and ImageErrorCode variants via the Rust source.
• Refactor: Replaced native_toolchain_rs with native_toolchain_rust.
• Refactor: Simplified Rust code, removed api.rs.
• Refactor: Simplified encoder API and native implementation to keep only JPEG quality as a configurable encoding option.
• Refactor: Marked PixerMetadata final.

0.0.5

• Breaking: Replaced Pixer.encode(ImageFormatEnum, {quality}) with encoder objects.
• Added PixerJpegEncoder(quality: ...) with validation.

0.0.4

• Added JPEG quality support to Pixer.encode() via quality.
• Improved binding generation to resolve the active macOS SDK with xcrun.

0.0.3

• Fixed build hook for web platform.

0.0.2

• Breaking: invert() now returns a new Pixer instead of mutating in-place.
• Breaking: Removed deprecated resizeToFit() method (use resize() instead).
• Breaking: Renamed FFI functions to align with Rust image crate conventions:
  • encode -> write_to
  • crop -> crop_imm
  • rotate_90/180/270 -> rotate90/180/270
  • flip_horizontal/vertical -> fliph/flipv
  • brightness -> brighten
  • contrast -> adjust_contrast
• Added metadata caching to avoid redundant FFI calls for width, height, colorType.
• Added bounds validation for crop() - now throws InvalidDimensionsException if crop rectangle exceeds image bounds.
• Added hash verification for native assets.
• Added generate_bindings.sh script to automate cbindgen + ffigen workflow.
• Improved error handling in load functions - now throws specific exceptions (IoException, DecodingException, UnsupportedFormatException) instead of generic LoadException.
• Improved documentation for blur() method.

0.0.1

• Finalized the Dart API with typed exceptions.
• Added context to exceptions for clearer error messages.
• Added a finalizer and isDisposed for safer resource handling.
