feat(docker): Replace custom plugins with KDE kimageformats#2
Conversation
- Add multi-stage Docker build with 7 optimized stages - Build and install Qt image plugins: qt-avif-image-plugin, qt-jpegxl-image-plugin, qt-heic-image-plugin - Build libjxl 0.10.2 from source (required version not in Ubuntu noble) - Use system packages for AVIF (libavif16) and HEIC (libheif1) - No YACReader source code changes - uses Qt's dynamic plugin loading - Improves build caching and reduces rebuild times Enables support for modern image formats without code modifications, following YACReader's Qt plugin architecture as suggested in YACReader#498
- Replace 3 separate image plugin builders (AVIF, JXL, HEIC) with single kimageformats build - Reduce Dockerfile from 8 stages to 6 stages (25% reduction) - Build kimageformats 6.0.0 from KDE frameworks (patched for Qt 6.4 compatibility) - Support AVIF (avif, avifs) and JPEG XL (jxl) formats - Add 30+ bonus image formats (PSD, QOI, XCF, HDR, etc.) - Simplify build dependencies and maintenance - Note: HEIC/HEIF support not included (kimageformats 6.0.0 limitation) This provides a minimal diff alternative to PR YACReader#499 as requested by maintainers, using well-maintained KDE framework instead of multiple custom plugin builds.
- Remove libheif-dev from kimageformats builder (HEIC/HEIF not supported in v6.0.0) - Remove libheif1 from runtime dependencies - Reduces build complexity and image size - No functional change since HEIC/HEIF wasn't working anyway
- Step-by-step testing instructions - Expected outputs and success criteria - Known limitations (HEIC/HEIF not supported) - Troubleshooting section - Comparison with original PR YACReader#499 approach
