Dariusz L	ccfa2b6cfb	Add shape mask preview system for expansion and feather sliders ... 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.	2025-07-26 00:16:11 +02:00
Dariusz L	24ef702f16	Add custom shape mask menu with expansion and feathering ... 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.	2025-07-25 18:40:21 +02:00
