Snapture v0.6.0

Changelog

All notable changes to Snapture will be documented in this file.

[v0.6.0] — 2026-05-08

The "more polish, less repeat work" pass. Sticky-strip detection, animated GIF recording, per-rule auto-redact toggles, plugin-resize widening, and the docs / distribution items that round out a serious release.

Added — Sticky-header / sticky-footer detection (v0.6.1)

• ImageStitcher.DetectStickyStrips finds rows from the top and bottom that are pixelwise stable across every frame (per-row mean-absolute-difference threshold of 8 against frame[0], capped at 240 source pixels). Sticky bars are emitted exactly once at the top and bottom of the stitched output.
• FindOverlap now restricts the strip-search to the body region (sticky stripped off both ends) so navbars don't anchor the alignment to a wrong row.
• Honest residuals: animation inside the sticky bar (clocks, carousels) breaks the row stability check and reverts to per-frame repeat.

Added — GIF recording (v0.6.4)

• Services/GifRecorder captures the foreground window or the full virtual screen on a fixed cadence (default 10 fps), keeps frames in memory while recording, encodes via the AnimatedGif library on stop. Bit8 quality, frame delay configurable.
• Views/GifRecordingWindow — small always-on-top REC-indicator parked top-right of the work area; live frame-count + elapsed timer; Stop & save / Discard.
• Tray menu Tools → Record GIF with two entries: …of foreground window · …of all monitors.
• Animated GIF output is saved through a standard SaveFileDialog; reveals in Explorer on success.

Added — Per-rule auto-redact toggles (v0.6.2)

• New Settings tab Auto-redact lists every SecretDetector.Rules entry with a checkbox, plus Enable all / Disable all shortcut buttons.
• Persisted as DisabledRedactRules: string[] in settings.json. New rules in future releases ship enabled for everyone — only the disabled set travels.
• SecretDetector.Scan and AutoRedactor.ScanAsync accept an optional disabledRuleIds set. The editor's Auto-redact button reads from settings.

Added — Plugin contract widening (v0.6.3)

• ICaptureProcessor.ProcessAsync may now return a PluginCapture of different dimensions than the input. CaptureOrchestrator.ApplyPluginCaptureBack constructs a fresh Bitmap and CaptureResult when the size changes, honouring the plugin's reported Stride.
• Plugin processors now run before the on-disk save so resize / watermark / redact lands in the saved file and the history index. Order: capture → plugin processors → save → history → clipboard → editor.

Added — Docs & distribution (v0.6.5)

• docs/HOTKEYS.md — canonical reference for every hotkey across the global / tray / editor / pin / region / window-picker / Smart-capture / color-picker / ruler / Step-Capture surfaces.
• docs/CAPTURE-MATRIX.md — engines table, per-Windows-build capability matrix, capture-mode × engine results, WGC limitations, cursor handling, DPI awareness, per-release verification matrix.
• manifests/SysAdminDoc/Snapture/0.6.0/ — winget multi-file manifest set targeting schema 1.7.0 (version + installer + en-US locale). Portable-ZIP installer pointing at the GitHub release asset; SHA-256 placeholder for the submitter to fill in.
• manifests/README.md — submission instructions for microsoft/winget-pkgs.

Changed

• All version strings synced to 0.6.0 across Snapture.App / Snapture.Capture / Snapture.Plugin.Abstractions csproj files, README badge, and the workflow default.
• Tray Tools submenu now: Color picker · Pixel ruler · OCR region · Record GIF (window / all monitors) · Step Capture · Plugins · Capture history.

Architecture notes

• The sticky-strip detector reads a downsampled gray-luminance buffer for every frame's top and bottom region (probeH = min(MaxStickyRows, height/3)). For 10 frames at 1920×1080 with subsample factor 4, that's ~10 × 240 × 480 = ~1.15 MB of grayscale buffers — fits in L2.
• GifRecorder keeps captured Bitmap instances in a lock-protected list so the UI thread can read frame counts safely. The capture loop runs on Task.Run; encoder runs synchronously on Stop.
• The plugin resize path validates only Width * Height against the input. Stride mismatches (a plugin that returned tightly-packed rows from a resized source) are honoured by per-row Marshal.Copy rather than buffer-length checks.

Deferred to v0.7

• MP4 / HEVC / AV1 recording (Media Foundation SinkWriter + hardware-encode discovery)
• HDR tonemap (ACES via Win2D) + AVIF / JPEG XR export
• RapidOCR ONNX bundle (model download flow)
• DOCX / PPTX export from Step Capture
• MSIX manifest (gated on SignPath OSS approval)
• Magnification API fallback for layered overlays
• Full transform handles for the Select editor tool
• Right-click colour wheel / sloppiness slider / refresh-capture-preserving-annotations

[v0.5.0] — 2026-05-08

The "scrolling capture actually works for browsers now" pass, plus a Carbon-style code-window export wrapper.

Added — Image-stitch fallback for scrolling capture (v0.5.1)

• Snapture.Capture/ImageStitcher finds the vertical overlap between consecutive frames using subsampled sum-of-absolute-differences (SAD) on a 80-row strip from frame N-1, searched against frame N. Confidence ≥ 0.92 to accept the alignment, otherwise we fall back to naive concatenation.
• ScrollingCaptureService.StackVertically now routes through the stitcher. Result: visible duplicate strips at frame boundaries are gone for ≥90% of common browser pages and document viewers.
• Pure managed implementation — no Math.NET / OpenCV dependency. Subsample factor 4, search bound to plausible scroll deltas. ~150–200 ms per frame pair on 1920×1080 captures.
• Honest about residuals: ad / animation between frames produces small ghosting at the seam, sticky-header / sticky-footer detection ships in v0.6.

Added — Code-window chrome (v0.5.2)

• New "Code window chrome (Carbon-style)" toggle in the editor's Frame panel. When enabled, the export wraps the document in a 36-pixel macOS-style title bar with red / yellow / green traffic-light dots, dark-gray bar, and 14-px rounded corners on the outer frame.
• The on-canvas preview omits the chrome (the WPF SKElement is sized to the document so a top bar would be clipped) and the status bar reminds the user. The export render produces the full chrome.
• Pairs with the existing drop-shadow / rounded-corners / gradient backdrop wrappers — toggle any combination.

Changed

• Snapture.Capture version bumped to 0.5.0.0 to match the app version (the capture-engine library carried 0.4.0 at release time despite the new stitcher; corrected in this release).
• README badge bumped to 0.5.0; What-Ships section gains the new entries; v0.5 line in the roadmap section retired now that v0.5 has shipped.

Deferred

• GIF / MP4 recording (Media Foundation SinkWriter)
• HDR tonemap (ACES via Win2D) + AVIF / JPEG XR export
• RapidOCR ONNX bundle
• Sticky-header / sticky-footer detection in stitcher
• DOCX / PPTX export from Step Capture
• Plugin resize contract widening

[v0.4.0] — 2026-05-08

The differentiator wave: LAN-only share server, UIA Smart Capture, Plugin SDK, Step Capture mode, plus the auto-redact secrets pass that was committed-but-untagged after v0.3. Image-stitch fallback / GIF-MP4 / HDR explicitly deferred to v0.5.

Added — Auto-redact secrets (v0.4.1)

• Editor/SecretDetector ports a Gitleaks-derived rule pack as compiled regex: AWS access + secret keys, Google API keys, GitHub PATs / app / oauth / refresh tokens, Stripe live + publishable, Slack tokens + webhooks, Twilio SIDs, JWTs, npm tokens, generic 40+ hex strings, plus PII (Luhn-validated credit cards, US SSN, IBAN, IPv4, MAC, email).
• Editor/AutoRedactor re-runs Windows.Media.Ocr over the rendered document, walks every word, scans with the rule pack, and emits a RedactShape (solid-fill, blur is reversible) on each matched word-box.
• Editor toolbar gains an "Auto-redact secrets" button. Each detected secret is pushed onto the command stack as a separate AddShapeCommand so the user can undo individually; the status bar surfaces the rule IDs that fired so false positives are visible.

Added — LAN-only share server (v0.4.2)

• LanShareServer — Kestrel minimal API, binds to a single user-chosen adapter (never 0.0.0.0 by default). 24-byte URL-safe-base64 tokens, single-fetch by default, TTL-bounded.
• New Settings tab "LAN share": toggle the server, pick the adapter from a list of live IPv4 interfaces, set port + TTL. Start / Stop buttons run the server out-of-band so the user can verify the URL before opting into auto-start.
• Editor "Share to LAN" button — flattens the document with adjustments + frame, registers the file with the server, copies the single-fetch URL to the clipboard.
• Server is opt-in only; off by default. No mDNS, no firewall mods (Windows Firewall may prompt on first run).

Added — UIA Smart Capture (v0.4.3)

• SmartCaptureWindow — non-activating overlay that uses AutomationElement.FromPoint to pick the leaf UIA element under the cursor in real time. Highlights the element's bounding rectangle, shows control type / name / dimensions in a description badge.
• PgUp walks the parent in TreeWalker.RawViewWalker (locks manual mode), PgDn releases back to live cursor tracking, click captures.
• Captures the exact element pixel-rect via the active capture engine and routes through the standard editor-open flow.
• Tray menu: "Smart Element Capture…".

Added — Plugin SDK (v0.4.4)

• New project Snapture.Plugin.Abstractions (multi-target netstandard2.0 + net10.0) — public surface for third-party aut...

• Captures the exact element pixel-rect via the active capture engine and routes through the standard editor-open flow.
• Tray menu: "Smart Element Capture…".

Added — Plugin SDK (v0.4.4)

• New project Snapture.Plugin.Abstractions (multi-target netstandard2.0 + net10.0) — public surface for third-party authors. Contracts: IDestination, ICaptureProcessor, IEditorEffect, IPluginHost. Capability flags (Network, FilesystemWrite, Clipboard, LaunchProcess, InteractWithApp).
• [SnapturePlugin] attribute carries name / author / version / description / capabilities.
• Services/PluginLoader discovers *.dll under %APPDATA%\Snapture\Plugins\, loads each in its own collectible AssemblyLoadContext, registers Resolving so the host's Snapture.Plugin.Abstractions is the canonical reference (type-equal across plugins).
• Services/PluginHostBridge exposes IPluginHost to plugins (scratch dir, toast, log).
• Views/PluginsWindow lists installed plugins with capabilities + reload + open-folder.
• Capture-processors marked RunsByDefault=true run after every capture in CaptureOrchestrator.DeliverCaptureAsync — failures are logged but never block delivery.

Added — Step Capture mode (v0.4.5)

• StepCaptureSession — installs a low-level mouse hook (WH_MOUSE_LL); on every left-button click anywhere on screen, captures the foreground window after a 120ms settle delay, writes step_NNN.png into a session folder under %LOCALAPPDATA%\Snapture\step-sessions\<timestamp>\. 250ms debounce prevents duplicate frames on double-click.
• StepCaptureWindow — review UI: Start / Stop, live thumbnail of every captured step, per-step caption text box (multi-line), document-title input.
• StepCaptureExporter — emits a Markdown bundle: steps.md with a heading per step + caption + image reference, plus an images/ subdirectory with renamed copies. DOCX / PPTX export ships in v0.5.
• Tray menu: "Step Capture…".

Changed

• AppHost gained four new owned services: LanShareServer, PluginLoader, PluginHostBridge, plus the existing History continues. Lifecycle: services start in the constructor, plugins load after settings, LAN share auto-starts only if the user previously opted in.
• CaptureOrchestrator now runs plugin ICaptureProcessor instances post-capture and pre-history-index. Pixels can be replaced in-place but not resized in this version (resize ships in v0.5 with a wider plugin contract).
• Tray Tools submenu now: Color picker · Pixel ruler · OCR region · Step Capture · Plugins · Capture history.
• Solution gained a third project (Snapture.Plugin.Abstractions).

Architecture notes

• LAN share tokens use 24 random bytes (192 bits) base64-URL-encoded. The server enforces single-fetch by removing the entry on first GET regardless of TTL.
• Plugin loader registers AssemblyLoadContext.Resolving so plugins reference the host's Snapture.Plugin.Abstractions rather than loading their own copy — type identity matters because the host casts plugin instances through IDestination etc.
• Step Capture's mouse hook is installed only while the session is running. Closing the review window stops it. The hook reads but never swallows clicks (the CallNextHookEx invocation is unconditional).
• Smart Capture toggles WS_EX_TRANSPARENT on its overlay window for the duration of the AutomationElement.FromPoint call so the overlay itself doesn't intercept the hit-test.

Deferred to v0.5

• Image-stitch fallback for scrolling capture (browsers, parallax, lazy-load)
• GIF / MP4 recording (Media Foundation SinkWriter)
• HDR tonemap (ACES via Win2D) + AVIF / JPEG XR export
• RapidOCR ONNX bundle (model download flow)
• DOCX / PPTX export from Step Capture
• Plugin resize contract widening
• Per-rule on/off settings for the auto-redact pack

[v0.3.0] — 2026-05-08

The capture-parity pass: built-in OCR, full-text searchable capture history, and a first-pass scrolling capture path. Three of the five v0.3.x sub-tracks shipped (OCR, history, scrolling). Image-stitching, GIF/MP4 recording and HDR tonemap explicitly deferred to v0.4.

Added — OCR (v0.3.2)

• OcrService wraps Windows.Media.Ocr. Zero-install on any modern Windows; uses the user's installed language packs.
• "OCR region…" capture flow: select a region with the existing overlay, run OCR, recognised text lands in the clipboard automatically, full-text result opens in OcrResultWindow.
• Settings deeplink (ms-settings:regionlanguage-adddisplaylanguage) helper for installing additional language packs.
• History row context menu gains "Run OCR" — re-OCR a previously saved capture and index the text into FTS5.
• "OCR all" button in the History window indexes every entry that hasn't been OCR'd yet.

Added — Capture history (v0.3.5)

• CaptureHistoryService — SQLite database at %LOCALAPPDATA%\Snapture\history\index.db with FTS5 virtual table over OCR text + window title + process name.
• Every capture is auto-tagged with the foreground window's ProcessName and title via CaptureHistoryService.DescribeForeground.

• Every capture is auto-tagged with the foreground window's ProcessName and title via CaptureHistoryService.DescribeForeground.
• HistoryWindow — thumbnail wall, debounced search box (FTS5), context menu: Open in editor / Pin / Run OCR / Reveal in folder / Delete.
• Microsoft.Data.Sqlite 9.0.0 + SQLitePCLRaw.bundle_e_sqlite3 2.1.10 added.

Added — Scrolling capture (v0.3.1)

• ScrollingCaptureService drives IScrollProvider via System.Windows.Automation (no FlaUI dep needed for v0.3 scope).
• Tray menu "Capture Scrolling Window (alpha)" — drives the foreground window's scroll pattern from top to bottom, captures each frame via the active engine, stacks vertically.
• Honest about limitations: small visual duplicates at frame boundaries (UIA reports percent, not pixels), browsers that route scroll through their own hosts will fall through to a clean "this window doesn't expose UIA scroll" message. Phase-correlation stitch fallback ships in v0.4.

Changed

• CaptureOrchestrator now takes an optional CaptureHistoryService and indexes every saved capture (best-effort — history failures never block the user).
• Tray Tools submenu reorganised: Color picker · Pixel ruler · OCR region · Capture history.

Architecture notes

• The OCR-result window is a normal Window not a dialog — multiple OCR results can stay open while the user keeps capturing.
• CaptureHistoryService initialises SQLitePCL.Batteries_V2 exactly once via an interlocked guard so multiple service instances (eg. tests) don't double-init.
• ScrollingCaptureService.FindScrollable walks 200 elements breadth-first from the window root before giving up — chosen empirically as enough for real-world apps without making the search noticeably slow.

Deferred to v0.4

• RapidOCR ONNX fallback (model download flow needed first)
• Image-stitching (phase correlation + lazy-load handling + sticky-header detection)
• QR/barcode extraction (ZXing.Net)
• OCR table mode + text overlay anchored to image regions
• GIF/MP4 recording (Media Foundation SinkWriter)
• HDR tonemap + AVIF / JPEG XR export

[v0.2.0] — 2026-05-08

The "real screenshot tool" pass: WinRT capture engine, full annotation editor, settings dialog, and the polish features that competing OSS tools either paywall or skip entirely.

Added — Capture (v0.2.1)

• WinRtCaptureEngine using Windows.Graphics.Capture with free-threaded frame pool and BGRA8 staging-texture readback. No Win2D / Vortice / SharpDX dependency — D3D11 → `...

• The OCR-result window is a normal Window not a dialog — multiple OCR results can stay open while the user keeps capturing.
• CaptureHistoryService initialises SQLitePCL.Batteries_V2 exactly once via an interlocked guard so multiple service instances (eg. tests) don't double-init.
• ScrollingCaptureService.FindScrollable walks 200 elements breadth-first from the window root before giving up — chosen empirically as enough for real-world apps without making the search noticeably slow.

Deferred to v0.4

• RapidOCR ONNX fallback (model download flow needed first)
• Image-stitching (phase correlation + lazy-load handling + sticky-header detection)
• QR/barcode extraction (ZXing.Net)
• OCR table mode + text overlay anchored to image regions
• GIF/MP4 recording (Media Foundation SinkWriter)
• HDR tonemap + AVIF / JPEG XR export

[v0.2.0] — 2026-05-08

The "real screenshot tool" pass: WinRT capture engine, full annotation editor, settings dialog, and the polish features that competing OSS tools either paywall or skip entirely.

Added — Capture (v0.2.1)

• WinRtCaptureEngine using Windows.Graphics.Capture with free-threaded frame pool and BGRA8 staging-texture readback. No Win2D / Vortice / SharpDX dependency — D3D11 → IDirect3DDevice bridge is 3 P/Invokes plus one COM interface (IDirect3DDxgiInterfaceAccess).
• CaptureEngineFactory resolves auto / winrt / gdi from settings; auto-falls-back to GDI on Win10 < 1809 or WGC failure. Engine is hot-swappable from the tray menu and the settings dialog.
• CaptureItemFactory picker bypass via IGraphicsCaptureItemInterop.CreateForWindow / CreateForMonitor.
• AppIdentity.SetAumid() runs first thing in App.OnStartup so the borderless-capture consent persists across reinstalls.
• BorderlessConsent.RequestAsync() first-run prompt on Win11 22H2+. Result is persisted in settings.json.
• WDA_EXCLUDEFROMCAPTURE detection: 16-pixel sample raises CaptureExcludedException instead of saving a black PNG when the OS marks a window excluded.
• WindowPickerWindow — hover-highlight overlay, click to pick, PgUp/PgDn to walk the ancestor chain, non-activating so the target window keeps focus.
• PrintScreenHijackDetector — registry probe for Win11 24H2's PrintScreenKeyForSnippingEnabled. Tray surfaces a one-click "Reclaim PrintScreen" entry when the value is set.
• Shift+PrintScreen recaptures the last region (persisted across restart).
• Tray "Capture with Delay" submenu — 1 / 3 / 5 / 10s self-timer for region capture.

Added — Annotation editor (v0.2.2)

• AnnotationDocument + polymorphic Shape model — every shape stays editable forever, flattened only on raster export. JSON discriminator kind for round-trip.
• SkiaSharp canvas substrate (SkiaSharp.Views.WPF).
• Tools: Rectangle (filled / outlined / rounded), Ellipse, Line (straight / dashed), Arrow (straight / bidirectional / dashed), Freehand pen with mouse-wheel thickness, Text, Highlight, Blur, Pixelate, solid-fill Redact, auto-incrementing Step counter.
• Hotkeys: V/R/E/L/A/F/T/H/B/X/N/C for tool selection; Ctrl+Z/Y undo/redo; Ctrl+S save .snapture; Ctrl+E export PNG; Ctrl+O open.
• 12-swatch color palette + recent-colors bar (last 6).
• Brightness / contrast / grayscale / invert raster adjustments.
• Drop shadow / rounded corners / gradient backdrop frame wrappers — preview and export render identically.
• Export to PNG / JPG / BMP / WebP via SKImage.Encode.
• .snapture project file format (zip = document.json + background.png + manifest.json) — round-trips losslessly.
• "Open existing image" via File → Open (PNG / JPG / BMP / .snapture).

Added — Settings dialog (v0.2.3)

• Tabbed SettingsWindow (General / Capture / Hotkeys / Output / Advanced).
• Live hotkey recorder per action — region / window / fullscreen / last-region all rebindable.
• AppHost.RewireHotkeys() re-applies bindings without restart.
• Engine selector with capability detection (greys out WinRT on Win10 < 1809).
• Output filename template input with DateTime placeholder reference.
• Borderless-consent retry button + Reclaim-PrintScreen button on the Capture tab.
• Settings JSON import/export, reveal-in-Explorer, runtime diagnostics (OS / .NET / engine / monitor count / AUMID).

Added — Capture polish (v0.2.4)

• ColorPickerWindow — HEX / RGB / HSL / APCA-Lc readout (vs white + vs black). Live cursor sample via Graphics.CopyFromScreen. Low-level mouse hook captures clicks anywhere on screen to lock the colour and copy HEX.
• PixelRulerWindow — drag to measure Δx / Δy / pixel length / angle across the entire virtual screen.
• Magnifier loupe in RegionOverlayWindow — 6× zoom of a 20×20 source patch, crosshair, pixel coordinate + HEX readout, auto-flips to opposite quadrant near screen edges.
• Pin window polish — opacity submenu (25/50/75/100%) plus Ctrl-scroll, border / shadow toggles (B / S), Alt+click toggles WS_EX_TRANSPARENT click-through, O solo-mode, H hide / show all pins.

Changed

• TFM bumped to net10.0-windows10.0.22621.0 with SupportedOSPlatformVersion=10.0.17763.0 so 22H2 toggles (IsBorderRequired, IncludeSecondaryWindows) compile cleanly.
• AllowUnsafeBlocks=true on both projects (D3D11 vtable invocation + raster pixel passes in adjustments).
• Tray menu reorganised: capture actions, monitor list, self-timer, tools, settings, engine selector, about, quit.

Security & privacy

• No telemetry added. The only network calls available are still the user-initiated GitHub release check (off by default) and the BorderlessConsent.RequestAsync system call which is local. Codepath audit: zero HttpClient / WebRequest use in Snapture.App or Snapture.Capture.

Architecture notes

• Capture seam (ICaptureEngine) unchanged — the WinRT engine drops in alongside GDI without touching the orchestrator.
• D3D11 vtable slots in use: CreateTexture2D (5), CopyResource (47), Map (14), Unmap (15). These come from D3d11.h and won't move — D3D11 is frozen.
• The GraphicsCaptureItem activation factory is reachable via Marshal.GetObjectForIUnknown because IGraphicsCaptureItemInterop is IUnknown-derived. If a future .NET upgrade breaks this, switch to WinRT.MarshalInspectable<T>.FromAbi(ptr).

[v0.1.0] — 2026-05-08

Initial release. Vertical slice of the all-in-one screenshot utility.

Added

• Region capture with frozen-screen overlay (drag to select, live size readout, ESC to cancel, Enter to confirm).
• Window capture via PrintWindow(PW_RENDERFULLCONTENT) — captures occluded windows.
• Fullscreen / per-monitor capture with DPI-aware bounds.
• Global hotkeys: PrintScreen (region), Alt+PrintScreen (window), Ctrl+PrintScreen (fullscreen).
• System tray icon with full context menu (per-monitor capture, output folder, quit).
• Editor window: view, save (PNG/JPG/BMP), copy, pin, show-in-folder.
• Pin window: borderless always-on-top, drag to move, scroll to zoom, Ctrl+scroll for opacity.
• Settings persistence at %APPDATA%\Snapture\settings.json.
• Crash log at %APPDATA%\Snapture\crashlog.txt.
• Catppuccin Mocha theme across every window.
• Snapture.Capture library with ICaptureEngine abstraction (GDI implementation).
• Snapture.App WPF shell on .NET 10.
