Mark Shot v0.1.29

Features & Enhancements

• Independent Magnifier Frame Resize: The magnifier annotation now exposes resize handles on both the inner source viewfinder and the outer lens. Rectangle lenses get 8 corner/edge handles per frame; circular lenses get 4. Resizing either frame keeps magnifierScale constant by scaling the other frame proportionally, so the loupe ratio is preserved no matter which side the user grabs. The drag/translate logic moves into a dedicated shot_window_magnifier_drag.cpp to keep the annotation editing pass small and the resize flow self-contained.
• Rectangle Highlight & Invert Styles: The rectangle tool gains a style selector with three modes:
  • Stroke: existing outlined or filled rectangle with optional rounded corners.
  • Highlight: marker-pen overlay using CompositionMode_Multiply with a semi-transparent fill, mirroring the highlighter look but bound to a rectangle.
  • Invert: inverts the RGB pixels covered by the rectangle, with the outline stroke kept as a visual cue.
    The fill toggle and corner radius slider are hidden when Highlight or Invert is active, since those styles do not consume filled or cornerRadius.
• Persisted Annotation Tool Defaults: Tool defaults now survive across sessions through a dedicated state file at ~/.config/mark-shot/annotation-state.json. The persisted snapshot covers active color and opacity, text background color, per-tool widths (pen / shape / number / mosaic block / laser), rectangle fill / corner radius / style, magnifier scale and lens shape, arrow / highlighter / number badge styles, and text font family. Writes go through QSaveFile for atomic commits, triggered immediately after every default-changing entry point so a crash never leaves the file half-written. The state is loaded before UI construction so the toolbar reflects the saved defaults from the very first paint.

Bug Fixes

• Annotation Width State Consistency: Unified the standard stroke width used by Pen, Line, Arrow, Laser, Rectangle, and Ellipse tools while keeping Highlighter width, Number size, Text size, and Mosaic granularity independent. Mouse wheel and slider adjustments now flow through the same state update path, selected-object width changes persist correctly, and high-frequency width edits are debounced before writing history or disk state.
• Translation Target Language Controls: Added a target language selector to the OCR result floating panel and the pinned image context menu. The selector now uses a stable custom dropdown affordance, saves translation.targetLanguage, and clears stale pinned-window translation overlays when the target language changes.
