- Implement auto_orient_from_exif() that reads EXIF Orientation tag
and applies the correct rotation/flip for all 8 EXIF orientations
- Add aspect ratio lock toggle to resize step Width/Height mode
- When lock is active, changing width auto-calculates height from
the first loaded image's aspect ratio, and vice versa
- Uses recursive update guard (Cell<bool>) to prevent infinite loops
- Add rotate_watermark_image() using imageproc rotate_about_center
for 45/-45 degree rotations and image::rotate90 for 90 degrees
- Add render_text_to_image() helper that renders text to a
transparent buffer for rotation before compositing
- Apply rotation to single text, tiled text, single image, and
tiled image watermark modes
- Fix tiled image watermark to use actual overlay dimensions
(which change after rotation) instead of pre-rotation values
- Move watermark step after compress in processing pipeline to match
design doc order (resize, adjustments, convert, compress, metadata,
watermark, rename)
- Implement selective EXIF metadata stripping for Privacy and Custom
modes using little_exif tag filtering (GPS, camera, software,
timestamps, copyright categories)
- Add case conversion support to rename (none/lower/upper/title)
- Add regex find-and-replace on original filenames
- Wire case and regex controls in rename step UI to JobConfig
- Add regex crate dependency to pixstrip-core
Support {date}, {exif_date}, {camera}, and {original_ext} in rename
templates. Reads DateTimeOriginal and Model from EXIF metadata via
little_exif when these variables are used in templates.
Each ExpanderRow now remembers its expanded state between sessions
using a per-section key stored in SessionState. Replaces the global
detailed_mode toggle with granular per-section persistence.
Wire tiled, margin, and scale UI controls to JobConfig and pass
through to WatermarkConfig. Add tiled text and image watermark
implementations that repeat across the full image. Add font family
filesystem search for named fonts. Add WatermarkRotation enum.
PNG files now embed pHYs chunk for DPI when output_dpi is set, matching
the existing JPEG DPI support. Also fixed FontDialogButton signal handler
to properly unwrap the Option<FontDescription>.
Font picker using GTK FontDialog/FontDialogButton lets users choose
any installed system font for text watermarks. The selected font family
is passed through the processing pipeline and used to find the matching
font file on disk.
- Add output_dpi field to EncoderOptions
- Set JFIF pixel density header in JPEG output when DPI > 0
- Wire output_dpi from ProcessingJob through to encoder in both
parallel and sequential execution paths
- New settings page: Watch Folders with add/remove/edit controls
- Each watch folder has: path, linked preset dropdown, recursive toggle,
active/inactive switch, and remove button
- Watch folder config persisted in AppConfig
- Empty state message when no folders configured
Semi-transparent dialog-based tour with 6 stops covering step
indicator, workflow selection, image adding, navigation, menu,
and a final ready message. Skippable at any time. State persisted
via tutorial_complete flag in AppConfig.
Add output_dpi field to JobConfig, ProcessingJob, and Preset.
Connect the DPI SpinRow in the resize step's advanced options to
update the config value.
Implements actual extension file creation for Nautilus (Python
extension), Nemo (.nemo_action files), Thunar (custom actions XML),
and Dolphin (KDE service menu .desktop). Each extension creates a
"Process with Pixstrip" submenu with all presets listed. Toggle
switches in welcome wizard and settings now call install/uninstall.
- Play system notification sound via canberra-gtk-play when enabled
- Implement preserve_directory_structure in output_path_for to maintain
relative paths from input directory in output
- Add history_max_entries (default 50) and history_max_days (default 30)
to AppConfig
- Add prune() method to HistoryStore that removes old entries by age
and count limits
- Call prune after each history entry is added in the GUI
- Preserve history settings through settings dialog save/load cycle
- Add ResizeAlgorithm enum (Lanczos3/CatmullRom/Bilinear/Nearest) to core
- Thread algorithm selection from UI ComboRow through ProcessingJob to resize_image
- Add OverwriteBehavior enum (AutoRename/Overwrite/Skip) to core
- Implement overwrite handling in executor with auto-rename suffix logic
- Wire overwrite behavior from output step through to processing job
- Fix rotation/flip to apply when resize step is enabled, not just adjustments
- Add EncoderOptions struct with progressive_jpeg and avif_speed fields
- Pass encoder options through ProcessingJob to PipelineExecutor
- mozjpeg set_progressive_mode() called when progressive JPEG enabled
- AVIF encoder speed now configurable (was hardcoded to 6)
- run_processing uses CompressConfig::Custom when user overrides preset defaults
- Executor properly handles AVIF quality and PNG level in Custom mode
Track last_seen_version in session state. Show the What's New dialog
automatically when the version changes, but not on very first run
(where the welcome wizard is shown instead).
New AdjustmentsConfig with brightness, contrast, saturation, sharpen,
grayscale, sepia, crop to aspect ratio, trim whitespace, and canvas
padding. All wired from UI through to executor.
- Saturation uses luminance-based color blending
- Sepia uses standard matrix transformation
- Crop calculates center crop from aspect ratio
- Trim whitespace detects uniform border by corner pixel comparison
- Canvas padding adds white border around image
Executor now applies rotation, flip, resize, watermark, format
conversion, compression, renaming, and metadata handling. Previously
only resize, convert, and compress were active.
- Rotation: CW90/180/270 via image crate methods
- Flip: horizontal/vertical via image crate methods
- Watermark: text (imageproc + ab_glyph) and image overlay with
alpha blending, positioned via WatermarkPosition enum
- Rename: apply_simple or template-based renaming with counter
- Metadata: re-encoding strips EXIF; KeepAll copies back via little_exif
The executor now uses rayon's thread pool for parallel processing when
thread_count > 1. Progress updates are sent via mpsc channel from worker
threads. Falls back to sequential processing for thread_count = 1.
The PipelineExecutor now stores thread_count and pause_on_error
fields. When pause_on_error is enabled, the executor sets the
pause flag on failures so the user can review errors. The GUI
reads these settings from AppConfig before starting processing.
- Window size/position remembered between sessions via SessionStore
- Step indicator dots now clickable to navigate directly to that step,
with keyboard shortcut hints in tooltips
- File list in add-files dialog shows format and size per image,
header shows total count and total size
- Welcome dialog now saves skill level choice to config
- SessionState extended with window_width, window_height, window_maximized
- Welcome dialog buttons navigate between pages
- Done button closes dialog and marks first_run_complete
- Show welcome dialog on first launch only
- Add first_run_complete field to AppConfig with serde(default)
inotify-based folder watcher using the notify crate that detects new
image files, ignores non-image files, and supports start/stop lifecycle.
WatchFolder config struct for preset-linked watched directories.
Preset save/load/list/delete/import/export, config JSON persistence,
session state save/restore, and processing history log with append/clear.
All stored as JSON under ~/.config/pixstrip/.
ImageLoader: load image info (dimensions, format, file size) and pixels.
Discovery: find image files by extension, flat or recursive, single file or directory.
All 9 tests passing.
