Added\n- iOS & Android: animated GIF watermark support for video composition (per-frame overlay timing).\n- Example app: bundled sample GIF for video watermark testing.

Added

• iOS & Android: Animated GIF watermark support for video composition (per-frame overlay timing).
• Example app: added a bundled sample GIF for video watermark testing.

2.1.1

Fixed

• iOS: Resolved crash in composeText when converting colorArgb (0xFFFFFFFF) from Int64 to UInt32
  • Changed from unsafe Int64 → Int32 → UInt32 conversion to idiomatic UInt32(truncatingIfNeeded:)
  • Fixes "Fatal error: Not enough bits to represent the passed value" crash
  • Resolves issue #2
• iOS: Fixed text watermark clipping on right side
  • Improved canvas size calculation using CTLineGetImageBounds in addition to CTLineGetTypographicBounds
  • Ensures glyphs with italic, kerning, or ligatures are not clipped
  • Increased padding from 4.0 to 8.0 for safety margin

2.1.0

Improved

• Android & iOS: Significantly enhanced watermark quality for both images and videos
  • Android: High-quality filtering (FILTER_BITMAP_FLAG, DITHER_FLAG) with Matrix-based scaling for images; mipmaps + trilinear filtering (GL_LINEAR_MIPMAP_LINEAR) for video watermarks
  • iOS: CILanczosScaleTransform for superior quality scaling (replaces simple CGAffineTransform); highQualityDownsample option added to CIContext
  • Results in sharper, smoother watermarks with better detail preservation and anti-aliasing

Example

• Add save to gallery feature: users can now save watermarked images directly to their device photo library
  • Cross-platform implementation using gal package with proper permission handling
  • "Save to Gallery" button added to Result preview card

Release Notes (v2.0.0) — Android Joins The Party 🎉

• Android support is in! Images, text, and full video watermarking on API 24+.
• Same simple API across iOS and Android. No FFmpeg, no drama.

Highlights

• Video pipeline: MediaCodec + OpenGL ES with a smooth hardware path.
• Smart fallback: auto-switch to ByteBuffer YUV + GLES when hardware gets grumpy.
• Progress + cancel: real-time updates and graceful aborts for long jobs.
• Audio passthrough: best‑effort copy to keep your soundtrack rolling.
• Anchors that “just work”: positions apply to the displayed orientation.

Fixes

• No more 100% freeze: proper decoder → encoder EOS propagation.
• Upright overlays: fixed vertical flip for text/image watermarks on Android.
• Calmer logs: added WMLog gate; warnings/errors only by default.

Compatibility

• iOS: unchanged, solid as ever.
• Android: minSdk 24. HEVC/Dolby Vision support varies by device (we auto‑fallback).
• Emulators may have limited codec support—physical devices recommended for final checks.

Notes

• Default codec is H.264. Use HEVC when supported for extra sparkle.
• The plugin itself requests no permissions; your app handles file/media access.

Upgrade

• pubspec: watermark_kit: ^2.0.0
• Example app updated; try the “Video” tab to see end‑to‑end watermarking.

Added

• Android support for image, text, and video watermarking (API 24+).
  • Hardware Surface pipeline with automatic fallback to ByteBuffer YUV + GLES when needed.
  • Progress callbacks and cancellation, matching iOS.
  • Audio passthrough (best effort).

Fixed

• Android: prevent video tasks from hanging at 100% by properly propagating decoder EOS to the encoder.
• Android: corrected overlay vertical flip (image/text) so placement is upright while keeping coordinates unchanged.

Changed

• README updated for cross‑platform support; removed iOS‑only notes.
• Default logs reduced; added WMLog gate for verbose debugging on Android.

Notes

• Default codec is H.264; HEVC is used when supported. Some devices/emulators may not support HEVC/Dolby Vision.
• Minimum Android SDK is 24.

Full Changelog: https://github.com/tttocklll/watermark_kit/commits/v1.0.0

Added

• iOS video watermarking with progress/cancel (Core Image + AVFoundation Reader/Writer)
  • Pigeon APIs: composeVideo, cancel, and WatermarkCallbacks (progress/completed/error)
  • Dart: VideoTask exposes progress Stream and done Future
  • Example: dedicated Video tab with text/image watermark selection and output preview player

Changed

• Package description updated to reflect image + video support
• iOS Podspec metadata (summary/homepage/author) updated; minimum iOS set to 15.0

Notes

• Default codec is H.264; codec: 'hevc' can be used where supported
• Audio is passed through on a best‑effort basis

Added

• Text watermark support for images: new WatermarkKit.composeTextImage(...) API.
  • Placement options mirror composeImage (anchor, margin, offset, units).
  • Text style: fontFamily, fontSizePt (or widthPercent fit), fontWeight, colorArgb, opacity.
• Pigeon host method WatermarkApi.composeText and Dart client wiring (MethodChannel fallback retained).
• Example app: "Text Watermark" section and Compose Text action.

Changed/Chore

• README updated with text watermark usage and API reference.

Initial release.

Added

• iOS image watermarking plugin using Core Image (Metal-backed CIContext under the hood).
• Public API: WatermarkKit.composeImage(...) that composes a watermark image over a base image and returns encoded bytes.
  • Options: anchor, margin (with marginUnit: 'px'|'percent'), widthPercent, opacity, offsetX/offsetY (with offsetUnit), format: 'png'|'jpeg', quality (JPEG).
  • Anchors: topLeft, topRight, bottomLeft, bottomRight, center.
• Pigeon-based typed bridge (Dart/Swift) for composeImage.
• Example app to pick base/watermark from gallery, tweak options, and preview the result.

Changed/Chore

• Simplified README to state iOS support without version numbers.
• Committed example iOS CocoaPods setup (Podfile/lock, xcconfig includes) for reproducible builds.
• Removed unused template tests and misc files; tightened .gitignore.
