…tifact New `webp` module providing WebP encode/decode via Java 25 FFM API: - libwebp backend (cross-platform, if library available) - macOS ImageIO (CoreGraphics) backend - Windows WIC backend - Java ImageIO fallback (works with TwelveMonkeys plugin) - Bundled artifact with shaded+ProGuard-optimized TwelveMonkeys (~146K) - Testing UI with backend probing, encode/decode tests, and file preview - Updated README with WebP documentation and usage examples Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Fix CoInitializeEx invokeExact return type mismatch (WrongMethodTypeException) - Add libwebp-7 to library search names (MinGW/MSYS2 SONAME convention) - Configure testing module with shadow fat JAR and Main-Class manifest - Use ProGuard-optimized bundled webp artifact in testing Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Switch all encoder/decoder backends from byte[] RGBA to int[] ARGB — the native Java2D pixel format. This eliminates all manual byte-level pixel conversion and enables trivial interop with BufferedImage. - Extract DecodedImage from inner record to standalone class with toPng(), fromPng(), and isPngCached() methods (PNG caching) - Add isWebP() detection to PlatformWebPDecoder with backend overrides - libwebp: use WebPDecodeARGB/WebPEncode*BGRA (int[] ARGB = BGRA on LE) - macOS: use kCGBitmapByteOrder32Little|kCGImageAlphaFirst for encoding - Windows WIC: use GUID_WICPixelFormat32bppBGRA (native int[] = ARGB) - Java ImageIO: use getRGB()/setRGB() directly Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…d test suite - Replace buggy TwelveMonkeys VP8 decoder (43% pixel errors, issue #785) with ngengine image-webp-java pure Java WebP decoder - pixel-exact on all test images - Add 9 diverse test images (gradients, alpha, noise, checkerboard, solid, tall/wide) with libwebp reference PNGs for pixel-exact verification - Parameterize all backend tests (NgEngineDecoderTest, MacOSImageIOTest, WindowsWICTest, CrossBackendTest) over the full image set - Fix macOS ImageIO decoder bug: handle kCGImageAlphaNoneSkipLast (RGBX) format for opaque WebP images - Add NgEngineDecoder to CrossBackendTest for cross-backend pixel comparison - Remove JavaImageIODecoder, JavaImageIOEncoder and related ImageIO SPI config Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
