fixed the persistent shape preview bug where blue dashed lines would remain visible even when the user was no longer interacting with the slider. The issue was caused by race conditions and timing problems in the preview system.
Replaces full-canvas mask operations with getMaskForOutputArea() for significant performance improvements when processing masks for the output area. Refines shape mask removal and application logic to ensure correct mask state when changing expansion values or custom shapes, including auto-removal and re-application of masks. Adds throttling to shape preview rendering for better UI responsiveness. Improves mask removal to eliminate antialiasing artifacts and updates SAM mask integration to use correct output area positioning.
Refactors how custom output area shapes interact with extensions, ensuring the shape's position and mask application remain consistent when extensions are toggled. Moves output area shape logic to CanvasInteractions, tracks original shape position, and updates all rendering, IO, and mask operations to use the correct coordinates. Improves mask chunk clearing and adds chunked mask application/removal for shape masks, ensuring correct behavior with expansion and feathering.
Output area bounds are now positioned relative to the world, not always at (0,0), and are updated to match custom shape placement. Rendering and extension logic have been updated to respect the new bounds, and the mask tool now adjusts to the output area position. Also sets log level to DEBUG for development.
This update introduces a unified output area bounds system, allowing the output area to be extended in all directions independently of the custom shape. All mask and layer operations now reference outputAreaBounds, ensuring correct alignment and rendering. The mask tool, mask editor, and export logic have been refactored to use these bounds, and a new UI for output area extension with live preview and tooltips has been added. The code also improves logging and visualization of mask and output area boundaries.
Consolidates shape mask controls into a styled container, improves UI logic for showing/hiding sub-options, and updates slider initialization to reflect current values. Mask removal now always uses a hard-edged shape, even if feathering was previously applied, ensuring complete erasure of feathered areas. The mask application logic also clears the maximum possible mask area before applying the new mask to prevent artifacts from previous slider values. Checkbox and slider labels are updated for clarity.
Implements a real-time blue outline preview when adjusting the expansion and feather sliders in the custom shape mask UI. The preview updates dynamically while dragging, and applies the mask only on mouse release. Adds a viewport change listener to keep the preview in sync during zooming or panning. Refactors mask expansion/contraction to use fast morphological operations for sharp edges and updates mask drawing to handle holes correctly.
Introduces a CustomShapeMenu UI component for managing custom output area shape masks, including options for auto-applying the mask, expansion/contraction, and feathering. Updates Canvas and MaskTool to support these new mask operations, and ensures the menu is shown or hidden based on shape presence. Adds distance transform-based algorithms for accurate mask expansion and feathering.
