Q1View v2.5.0

Added

• Comparator: a synchronized selection rectangle for side-by-side region inspection. Press S to enter selection mode and drag a rectangle on either image; Comparator draws the same region on both panes so the corresponding area can be compared directly, and the rectangle stays locked to that image region while zooming, panning, or resizing. A width ×ばつ height readout is shown next to the rectangle, and the selection clears with Esc or a right-click. The selected region's score for the active metric (PSNR/SSIM, computed on the color-space-native planes, or LPIPS on the cropped region) is shown next to the whole-image score, so localized artifacts can be told apart from the global figure.
• Comparator: a selectable LPIPS perceptual backbone. The Metric menu now offers LPIPS-AlexNet (the existing fast, lightweight default) and LPIPS-VGG (a heavier, more detailed mode), each downloaded on demand the first time it is selected and verified by a pinned SHA-256. Results always carry the backbone in the label (for example LPIPS-VGG(0.0020)) since values from different backbones are not interchangeable, each backbone keeps its own per-frame cache, and the chosen metric is remembered across sessions.

Packaging

• The app, taskbar, and Start menu icons now render larger within their frame. The SVG masters' built-in safe margin was reduced (the rounded square grows from ~84% to ~91% of the icon), so the artwork reads bigger at every size while keeping the same glyph proportions and rounded corners. Regenerated from the Q1View.svg / Comparator.svg masters.

Commit 71b13d4. Full changelog: https://github.com/chammoru/Q1View/blob/v2.5.0/CHANGELOG.md

Q1View v2.4.4

Packaging

• Microsoft Store submissions now pin the listing description and short description to the curated text in docs/STORE_LISTING.md whenever release notes are updated, preventing stale Partner Center metadata with hard-wrapped mid-sentence line breaks from being resubmitted.

Commit 4b13ce9. Full changelog: https://github.com/chammoru/Q1View/blob/v2.4.4/CHANGELOG.md

Q1View v2.4.3

Packaging

• The taskbar and Start menu now show the rounded Q1View icon directly instead of a square plate behind it. The Microsoft Store package is now built with a resource index (resources.pri) so Windows can select the unplated icon assets that shipped in 2.4.1 but were previously never used, and the icon renders at full size again.

Q1View v2.4.1

Fixed

• Viewer: Ctrl+V now pastes the actual clipboard image. Paste previously routed the clipboard through a device-dependent bitmap and a temporary file written to the working directory, which the packaged Microsoft Store build could not reliably write, so a stale or unrelated image could appear instead; it now reads the clipboard's device-independent bitmap and writes a verified temporary file before opening it.

Packaging

• Taskbar and Start icons no longer show a square plate behind the rounded Q1View icon. The Microsoft Store package now ships unplated target-size logo assets, so Windows renders the transparent rounded icon directly instead of compositing it onto a square background.

Commit c00bf9d. Full changelog: https://github.com/chammoru/Q1View/blob/v2.4.1/CHANGELOG.md

Q1View v2.4.0

Added

• Viewer: press D to cycle through the preset resolutions for raw input,
  mirroring how N advances the color space. The shortcut is ignored for
  sources with an intrinsic size (decoded images and video).

Fixed

• Viewer: stepping through a folder with PgUp/PgDn (and Home/End) no longer
  resizes the window around each image. The window keeps its size and the next
  image is fit into the existing viewport, so browsing mixed-resolution folders
  stays steady instead of jumping between sizes and in/out of a maximized frame.
  A fresh open still sizes the window to the image. Fit now shrinks large images
  to fit but never upscales past 1:1, so small images stay crisp at 100%.

Packaging

• Refreshed the Viewer and Comparator application icons and the Microsoft Store
  tile and logo assets, regenerated per size from vector masters for sharper,
  more consistent edges at every scale.

Developer

• Qt viewer: a --selftest mode plus committed raw-format fixtures and a
  headless smoke check. viewer-qt.yml now runs ctest after the build,
  opening each fixture (yuv420, nv12, nv21, yuv420p10le, p010, grayscale,
  rgb888, bgr888, rgba8888, bgr565) under the offscreen QPA platform on
  Linux/macOS/Windows.
• Documented the experimental Qt viewer build and its qtmultimedia
  requirement in the development guide.

Q1View v2.3.1

Fixed

• Comparator: LPIPS model downloads now honor the current user's Windows proxy,
  PAC, and auto-detect settings in addition to the WinHTTP default proxy.

Commit 5e31cfc. Full changelog: https://github.com/chammoru/Q1View/blob/v2.3.1/CHANGELOG.md

Q1View v2.3.0

Added

• Comparator: added LPIPS as a perceptual image-quality metric backed by an
  ONNX Runtime model. The LPIPS model is downloaded on demand, verified with
  SHA-256, cached under the user's local Q1View data directory, and computed
  lazily so metric switching stays responsive.
• Viewer: the bottom progress bar now shows playback time alongside the frame
  counter when a valid timing FPS is available. The readout uses a compact
  one-decimal format such as 00:01.2 / 00:10.0 and falls back to the existing
  frame-only display when timing would be misleading.

Fixed

• Comparator: opening two files from the same image sequence in a single
  multi-file operation now treats them as explicit single-image panes instead
  of comparing different offsets of the same discovered sequence.

Developer

• Visual Studio project files now target the MSVC v143 toolset by default.
• Added ONNX Runtime dependency provisioning for LPIPS builds.
