Q1View\n\n[![Windows](https://img.shields.io/badge/platform-Windows-0078D6)](#download)\n[![Viewer](https://img.shields.io/badge/app-Viewer-2EA44F)](#what-you-get)\n[![Comparer](https://img.shields.io/badge/app-Comparer-2EA44F)](#what-you-get)\n[![HEIF](https://img.shields.io/badge/HEIF%2FHEIC-supported-2EA44F)](#supported-inputs)\n[![AVIF](https://img.shields.io/badge/AVIF%2FAV1-supported-2EA44F)](#supported-inputs)\n\nQ1View is a Windows viewer and comparer for people who inspect pixels, decoded\nframes, raw buffers, and codec output.\n\n## Download\n\nGet the latest Windows x64 build from the\n[GitHub Releases page](https://github.com/chammoru/Q1View/releases/latest).\n\n- **Installer**: `Q1ViewSetup-x64.exe`\n- **Portable package**: `Q1View-windows-x64.zip`\n\nThe installer adds separate Start Menu entries for **Q1View Viewer** and\n**Q1View Comparer**.\n\n## What You Get\n\n- **Viewer** opens images, raw dumps, image sequences, videos, and clipboard\n  images with pixel-level inspection.\n- **Comparer** compares 2-4 sources with synchronized navigation, zooming,\n  color-space handling, PSNR, and SSIM.\n\n## Why Q1View?\n\n- Raw pixel formats are first-class: YUV, NV12/NV21, P010/P210, RGB/BGR/RGBA,\n  grayscale, packed RGB, and more.\n- Image folders can be treated like frame sequences.\n- Exact pixel values, coordinates, luma-only view, nearest-neighbor zoom, and\n  selected-region copy are built into the workflow.\n- Multiple Viewer windows can link input controls for synchronized inspection.\n- HEIF/HEIC/HIF and AVIF still images are supported in both Viewer and Comparer.\n- Unicode Windows paths are supported, including Korean file and folder names.\n- The release package includes the DLLs it needs, so users do not need to\n  install OpenCV or HEIF libraries separately.\n\nQ1View is not trying to be a photo library. It is built for Windows pixel\ndebugging, frame comparison, and quick visual checks during codec or image\npipeline work.\n\n## Supported Inputs\n\n- BMP, JPEG, PNG, TIFF, WebP\n- HEIF, HEIC, HIF\n- AVIF / AV1 still images\n- Video files supported by the packaged OpenCV/FFmpeg runtime\n- Raw frame dumps and clipboard images\n\n## Build From Source\n\nQ1View builds with Visual Studio 2019 or newer on Windows x64.\n\n```powershell\nmsbuild Viewer\\Viewer.sln /m /restore /p:Configuration=Release /p:Platform=x64\nmsbuild Comparer\\Comparer.sln /m /restore /p:Configuration=Release /p:Platform=x64\n```\n\nNormal builds restore OpenCV and libheif into `.deps` from published dependency\narchives. Dedicated GitHub Actions workflows refresh those dependency archives\nwhen needed.\n\n## Release Pipeline\n\nGitHub Actions builds Viewer and Comparer, stages the runtime files, creates the\nportable zip, builds the Inno Setup installer, and publishes release assets for\nversion tags such as `v1.0.9`.\n\nThe pipeline also supports Authenticode signing when signing credentials are\nconfigured through repository secrets.\n\n## Project Layout\n\n| Path | Purpose |\n| --- | --- |\n| `Viewer\\` | Single-source viewer application |\n| `Comparer\\` | Multi-pane frame comparison application |\n| `QVisionCore\\` | Image loading, raw color conversion, HEIF/AVIF fallback, metrics |\n| `build\\` | Packaging, signing, and dependency helper scripts |\n| `installer\\` | Inno Setup installer definition |\n| `docs\\` | Focused technical notes |\n\n## Videos\n\n| Intro | Viewer | Comparer |\n| --- | --- | --- |\n| [![Intro](https://img.youtube.com/vi/b8VgRVnrxL4/mqdefault.jpg)](https://youtu.be/b8VgRVnrxL4) | [![Viewer](https://img.youtube.com/vi/g6K9bRTKJjY/mqdefault.jpg)](https://youtu.be/g6K9bRTKJjY) | [![Comparer](https://img.youtube.com/vi/EybIIBZLV8Q/mqdefault.jpg)](https://youtu.be/EybIIBZLV8Q) |\n\nMore videos:\n\n- [Viewer 2](https://youtu.be/ROpGsgRDdRE)\n- [Source code](https://youtu.be/ZbpRkBzK64Q)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchammoru%2Fq1view","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fchammoru%2Fq1view","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fchammoru%2Fq1view/lists"}
