# Changelog

All notable changes to imajViewer are documented in this file.

## [Unreleased]

## [1.7.2] - 2026-10-25

### Fixed
- Rotating sometimes vanished before saving: the right-button double-click reset was
  detected on button *down* against the previous down time and position, so two rotate
  drags started quickly at nearly the same spot were treated as a double click — all
  effects (rotation included) were wiped and the second drag was ignored, so `Ctrl+S`
  saved an unrotated crop. A double click is now only counted for actual clicks
  (movement ≤ 4 px, decided on button up), a drag breaks the chain, and
  `pointer up` is matched by pointer id so a left-drag pan never counts as a click.

## [1.7.1] - 2026-10-25

### Added
- Zoom percentage badge at the bottom center, between the previous/next buttons: shown
  together with the hover controls, translucent background, live while wheeling
  (100% = one image pixel per screen pixel), recomputed on fill/fit toggle, image
  change and window resize.

### Changed
- Image header parsing (pixel size without decoding) moved from the viewer screen into
  `lib/services/image_header.dart`; the settings file-properties panel and the zoom badge
  use the same code.

## [1.7.0] - 2026-10-20

### Added
- Settings dialog shows the app version next to the name.
- Fine zoom: `Ctrl`+wheel zooms 1% per step (plain wheel stays 10% per step).
- Settings shortcut list completed: `Ctrl+O` (open), `Esc` (exit fullscreen), scroll/zoom,
  `Ctrl`+scroll fine zoom, left-drag pan, double right click (reset effects).

### Changed
- README: zoom feature line and shortcut table updated to match.

## [1.6.3] - 2026-10-20

### Fixed
- `SIGSEGV` while resizing the window. The GTK embedder's OpenGL compositor uploaded the frame using
  the window's new dimensions while its pixel buffer still held the previous size, so `memcpy` read
  past the end of the buffer (`engine/.../linux/fl_compositor_opengl.cc`). Fixed upstream in
  flutter#187626, which is not part of Flutter 3.44.7 — the Linux build now uses Flutter 3.47.7,
  where the compositor derives the texture size from the framebuffer itself.

## [1.6.2] - 2026-10-14

### Changed
- Crop save JPEG quality raised from 93 to 95.

## [1.6.1] - 2026-10-14

### Fixed
- Horizontal flip shortcut (`Ctrl+R`) never fired when the keyboard layout resolves the R key to a
  different logical key (reported with a Turkish/remote-desktop setup where the R key arrives as
  logical `T`). The shortcut now matches the physical R key position as well.

## [1.6.0] - 2026-10-14

### Added
- Horizontal flip (`Ctrl+R`): mirrors the image left-right about the viewport centre and clears
  the active effects (same reset as double right click); pressing `Ctrl+R` again restores the
  original orientation. Zoom/pan are kept.
- Crop save (`Ctrl+S`) now bakes the flip into the output as well, so the saved JPEG matches
  the mirrored view (also in combination with rotation).

## [1.5.0] - 2026-10-12

### Added
- Fill/fit mode (double-click) is now persisted in `window.json` and restored on the next launch
  and when switching images, instead of always resetting to fill.

## [1.4.2] - 2026-10-12

### Fixed
- Crop save dropped the blue channel's brightness/contrast offset (matrix index `m[13]`, the
  alpha coefficient, instead of `m[14]`), so saved JPEGs came out with a color cast whenever
  brightness or contrast was applied. Saturation/rotate were unaffected.

## [1.4.1] - 2026-10-11

### Fixed
- Crop save always writes JPEG (previously kept the source extension, e.g. PNG) — quality 93
- Crop save with rotation now saves the rotated view 1:1 instead of an unrotated bounding box

## [1.4.0] - 2026-10-11

### Added
- Crop save: saves the visible area at original resolution as JPEG quality 90 — title bar save button or Ctrl+S
  - Output name: original name + `_HHmmss` time suffix (e.g. `photo.jpg` → `photo_143025.jpg`)
  - If a file with the same name exists, nothing is written and a warning is shown
  - Active color effects (contrast/saturation/brightness) are baked into the output
  - With rotation active, the bounding box around the visible area is saved

## [1.3.2] - 2026-08-28

### Fixed
- Window position/size persistence under Wayland — forces X11 backend (XWayland) when an X server is available

## [1.3.1] - 2026-08-14

### Fixed
- Aspect ratio distortion on image switch — downsample now uses `ResizeImagePolicy.fit` (was `exact`, which forced 2048×2048 square and stretched non-square images)

## [1.3.0] - 2026-08-14

### Fixed
- `_imageSize` now resets on image switch (wrong swap threshold on navigation)
- Downsample now caps both dimensions, not just width (tall images no longer full-res decode)
- Image size listener leak in `loadingBuilder` — replaced with single `_readImageSize`
- Old downsample provider now evicted on full-res swap
- Removed `imageCache.clear()` that also dropped the live image (gallery flash)

## [1.2.0] - 2026-08-14

### Added
- Downsampling: large images decode at max 2048px on first load (RAM ~1.6MB)
- Full-res swap: zooming in past 1.5x stretch swaps to original resolution
- Internationalization: Turkish + English, auto-detected from system locale
- Zoom decodes at original resolution while zooming in (crisp details)
- Max zoom increased to 20x

### Fixed
- RAM leak on image switch — old providers now evicted + `ImageCache.evict()`
- Black screen flash during zoom (gapless playback)

### Changed
- App ID `com.example.imajviewer` → `com.softmediadesign.imajviewer`
- CI now runs `flutter analyze` and `flutter test` on every push
- `pubspec.yaml` description in English (open-source ready)

## [1.1.0] - 2026-08-06

### Fixed
- `Ctrl+Q` now closes the window reliably (`onKeyEvent` rework)
- Pan freeze regression on effect-applied images (root cause analysis)

### Added
- Navigation arrows (visible on hover)
- Settings window: folder sorting by time/name, print, shortcut info
- Print support (printing package, A4 fit)
- Title bar hover transparency
- Shader warmup — right-click effects no longer stutter on first use

## [1.0.1] - 2026-07-27

### Fixed
- Zoom/pan issues on large images
- Image provider memoize — repeated opens no longer reload from disk

### Changed
- Version now sourced from `pubspec.yaml` (single source of truth)

## [1.0.0] - 2026-07-22

### Added
- Initial release: ultra-lightweight image viewer
- Formats: PNG, JPEG, JFIF, WebP, BMP, GIF, WBMP
- Pan (left drag), zoom (wheel, cursor-centered), fill/fit toggle (double click)
- Contrast / saturation / brightness / rotate gestures
- Drag & drop, window position memory, set-as-default-viewer
- Linux (.deb) and Windows (setup.exe) installers
