CaptureImage v2.0.0

CaptureImage v2.0.0

CaptureImage 2.0 is a rewrite of the app around the same idea: arm the hotkeys, press one in
your game, get a clean screenshot. Settings from 1.x are carried over automatically.

Highlights

• New interface built with WPF and WPF UI: Fluent design,
  Mica, light / dark / high-contrast themes that follow Windows, resizable window that remembers
  its position.
• Three capture modes, each with its own hotkey — Window (Ctrl+Shift+F12), Region
  (Ctrl+Shift+F11) and Screen (Ctrl+Shift+F10). Region freezes every monitor and lets you drag
  an area (a click takes the whole screen); Screen captures the monitor under the mouse pointer.
  Works across monitors with different scaling.
• HDR screenshots — on HDR displays the full HDR frame is captured and tone-mapped to a normal
  image; the original can be kept next to it as JPEG XR (.jxr).
• Capture library — browse every capture with thumbnails, filter by game or HDR, open, show in
  folder, copy the image or its path, extract text (OCR), pin it on screen or move it to the
  Recycle Bin.
• Game profiles — per-game output folder, format, file name template and HDR setting, matched
  by executable path, executable name or Steam AppId. A profile can arm the hotkeys (and lock the
  game window) as soon as the game comes to the front. Create one from the Dashboard in one click.
• Start with Windows, start minimized to the tray, arm on startup, export diagnostics,
  import / export / reset settings.
• 11 languages with every string translated, following the Windows display language on first
  run; Arabic is laid out right to left.

Changed

• Runs on .NET 10 (LTS). The app is now framework-dependent: Setup (and the in-app updater)
  installs the .NET 10 Desktop Runtime when it is missing, so the first update from 1.x may ask for
  permission once. The installer shrank from about 100 MB to about 28 MB.
• Hotkeys use the Windows RegisterHotKey API and are registered only while armed. There is no
  global keyboard or mouse hook any more, and while disarmed your key combinations reach other
  apps untouched. Conflicts with other apps are detected and shown.
• The window list follows Windows events instead of polling WMI every two seconds.
• Settings, logs, the library index and thumbnails live in
  %LocalAppData%\poli0981\CaptureImage, outside the installer's folder, so reinstalling never
  wipes them. The 1.x settings.json is copied (the old file is left as it was) and migrated to
  the new format.
• Notifications appear inside the window when it is in front, otherwise as a small pop-up that
  never takes focus from a game and never shows up in screenshots.
• The tray icon shows a red dot while the hotkeys are armed; its menu can capture in every mode.
• The version is shown the same way everywhere, e.g. 2.0.0 (abc1234).
• Logs hide your user-profile path; window titles are logged only at the Debug level.

Fixed

• Pressing Esc while selecting a region reported "Capture failed"; pressing the hotkey again during
  a countdown could crash the app; an error during preview could leave it stuck.
• Captures could come out partly transparent, a new capture could overwrite an existing file, and
  encoding ran on the UI thread (the window froze while saving 4K images).
• Region selection worked only on the primary monitor and was offset at scaling other than 100%.
• After a graphics-driver reset, captures failed until the app was restarted; a few native objects
  leaked with every capture.
• Settings were not written atomically; a damaged file or one from a newer version was replaced by
  defaults without a backup; unknown fields were dropped; importing skipped validation and accepted
  network (UNC) paths.
• Notifications were invisible while the app was in the tray; the Import / Export buttons did
  nothing; "Start minimized" was ignored; the app had no icon.
• A second Windows user running the app filled the log with warnings; the foreground-window
  watcher could crash on exit.
• "Install update" ended the process without saving settings or removing the tray icon, and
  release notes never reached the Update page.
• File names now avoid reserved device names (CON, NUL, …), invisible bidirectional and
  zero-width characters, and names that are too long.
• Settings missing from the settings file — such as options added by an update — were turned off
  or set to zero instead of taking their default values.

Removed

• WinUI 3 / Windows App SDK, SharpHook, WMI, Stateless, ImageSharp and System.IO.Abstractions.
• "Auto-switch target on Alt+Tab": the Window hotkey captures the window in front unless you lock
  one on the Dashboard.
• The list of social profiles in About; other channels are listed at https://poli0981.dev/links.

Project

• Required pull-request checks: build and tests (with coverage), formatting, dead code, vulnerable
  and incompatibly licensed dependencies, a smoke test of the published app, end-to-end UI tests,
  PR title, dependency review, workflow lint and documentation links. CodeQL (extended queries), OpenSSF Scorecard and
  SonarCloud also review every change.
• Releases ship a CycloneDX SBOM, SHA-256 checksums and GitHub build-provenance attestations, and are
  published as drafts first.
• About and the documentation list the project contacts: contact@poli0981.dev and
  https://poli0981.dev/links.

Downloads

• CaptureImage-win-Setup.exe — installer (per-user). Windows 11 22H2 or later; installs the .NET 10 Desktop Runtime if it is missing.
• CaptureImage-win-Portable.zip — extract-and-run build without installer (needs the .NET 10 Desktop Runtime).
• *-full.nupkg, releases.win.json — update feed used by the in-app updater.
• SHA256SUMS.txt, *-sbom.cdx.json — checksums and CycloneDX SBOM.

Verify the download

The installer is not code-signed yet, so Windows SmartScreen shows "Unknown publisher".
Check the checksum or the build-provenance attestation before running it:

Get-FileHash -Algorithm SHA256 .\CaptureImage-win-Setup.exe   # compare with SHA256SUMS.txt
gh attestation verify .\CaptureImage-win-Setup.exe --repo poli0981/captureimg
