Redesigned the positioning system for the Blend Mode menu, inspired by the "Custom Output Area" logic. The menu now anchors precisely to the top-right corner of the viewport and stays in place during panning and zooming.
Added a smart selection frame for layers that dynamically switches between solid and dashed lines depending on visibility:
Functionality:
Solid line: visible edge segments, not covered by other layers
Dashed line: covered edge segments, obscured by layers with higher zIndex and opacity > 0.1
Refactored the "Output Area Size" button to use the new setOutputAreaSize method:
Correctly sets output area size and position based on current system logic (custom shape, extensions, outputAreaBounds)
Fully functional across all editor modes
New resizing logic:
Operates relative to the current center of the output area
Output area expands or contracts around its center without repositioning
Ensures center remains unchanged as expected
This fix provides precise control over layout dimensions and aligns with user expectations across workflows.
Added a clear first point distinction when drawing a custom shape: if the mouse cursor is near the beginning of a line (the shape can be closed), the first point is drawn in yellow and larger. This allows the user to see when they can close the shape with a single click. The code has been compiled and is ready to use. The functionality works as expected.
I updated src/css/custom_shape_menu.css with new styles for a modern look and feel, and I refactored src/CustomShapeMenu.ts to use a new HTML structure for the checkboxes that works with the updated CSS. The menu should now be fully functional with the new design.
moved all CSS from src/CustomShapeMenu.ts to a new file src/css/custom_shape_menu.css and updated the TypeScript file to use the external stylesheet. This improves code organization and maintainability.
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.
Introduced a drawTextWithBackground helper to centralize and simplify text rendering with backgrounds in CanvasRenderer (JS/TS). Updated all relevant usages to use this helper. Adjusted initial viewport x/y offsets in Canvas and Canvas.ts for improved default positioning.
Refactored notification utilities for a more modern, reusable notification system and added info/success/error notifications to the background removal (matting) workflow. Removed the custom error dialog in favor of notifications, and exposed all notification types for debugging. Updated imports and cleaned up notification-related code.
Adds a modern, type-based notification UI with support for success, error, info, warning, and alert styles, including a new showAlertNotification function. CanvasState now auto-corrects the node_id widget before saving state and notifies the user if a correction occurs. CanvasView centering logic now uses the actual canvas container for more accurate viewport adjustments.
Adds logic to adjust the canvas viewport to keep content centered when entering or exiting fullscreen mode. The adjustment calculates the difference in container sizes and updates the viewport position accordingly, improving user experience during fullscreen transitions.
Implemented an ESC key handler to allow users to close the fullscreen editor mode using the Escape key. Updated the editor button tooltip and the shortcuts documentation to reflect this new shortcut.
The mask is now drawn after layers but before all preview outlines, ensuring correct visual stacking. The redundant mask rendering code after the preview outlines has been removed.
Adds logic to restore outputAreaBounds from saved state if available, or fallback to a default for legacy saves. Also ensures outputAreaBounds is included when saving state, improving consistency across sessions.
Introduced a calculateDynamicWaitTime method to determine wait time before applying a mask, scaling the delay according to the image's pixel count. This improves responsiveness and reliability for different image sizes in the mask editor integration.
Replaces all uses of alert() with showErrorNotification or showSuccessNotification for improved user experience and consistency. Refactors canvas creation to use the createCanvas utility function across multiple files, reducing code duplication and improving maintainability. Also updates layer ID generation to use generateUUID.
Moved convertToImage, createMaskFromImageSrc, and canvasToMaskImage from MaskProcessingUtils and mask_utils to ImageUtils for better modularity and reuse. Updated imports in dependent modules to use the new locations. Removed duplicate implementations from mask_utils and MaskProcessingUtils.
Replaces direct usage of document.createElement('canvas') and manual context setup with the createCanvas utility across multiple utility modules. This change improves code consistency, reduces duplication, and centralizes canvas/context creation logic. Also updates notification usage in ClipboardManager to use showNotification and showInfoNotification utilities.
Extracted image upload, mask processing, notification, and preview update logic into dedicated utility modules. Updated MaskEditorIntegration and SAMDetectorIntegration to use these new utilities, reducing code duplication and improving maintainability.
Refactors the Canvas class to rename the 'canvasMask' property to 'maskEditorIntegration' for consistency. Updates all references and import to use the new name with the .js extension.
Renamed the CanvasMask class and file to MaskEditorIntegration for improved clarity and consistency. Updated all references in Canvas and SAMDetectorIntegration to use the new name.
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.
Introduces utility methods to eliminate code duplication in chunk operations, mask creation, and shape processing. Adds universal chunk processing, chunk operation, and canvas helper methods. Refactors shape mask application and removal to use unified logic, and consolidates morphological and feathering operations for masks. Improves maintainability and readability by centralizing repeated logic.
Introduces utility methods for chunk bounds calculation, intersection, and activation for better code reuse and clarity. Refactors shape mask application and removal to consistently account for output area extensions, and centralizes chunk empty status updates. Improves chunk activation logic for mask and shape operations to enhance visibility and maintainability.
Introduces active chunk management for mask drawing, activating only nearby chunks during drawing for performance. Updates the active mask canvas to show all chunks but optimizes updates to redraw only active chunks during drawing, reducing lag. Adds LRU-style tracking and safety limits for active chunks, and improves chunk activation logic for both drawing and mask application.
Introduces helper methods to reduce code duplication and improve readability in CanvasInteractions. Mouse coordinate extraction, event prevention, zoom operations, drag-and-drop styling, and layer wheel transformations are now handled by dedicated methods. This refactor centralizes logic, making the codebase easier to maintain and extend.
Cleaned up the codebase by removing unused or redundant methods from Canvas, CanvasIO, CanvasLayers, CanvasLayersPanel, CanvasRenderer, and MaskTool. This reduces code complexity and improves maintainability without affecting core functionality.
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.
Replaces the single large mask canvas with a chunked system, where mask data is stored in 512x512 pixel chunks. Updates all mask drawing, compositing, and manipulation logic to operate on these chunks, improving performance and scalability for large or sparse masks. The active mask canvas is now a composite of all non-empty chunks, and all mask operations (drawing, setting, clearing) are adapted to the new chunked architecture.
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.
Implements a real-time blue outline preview for shape mask expansion and feather adjustments in CustomShapeMenu, providing immediate visual feedback while dragging sliders. Adds a dedicated shape preview canvas and efficient morphological operations in MaskTool for sharp, fast previews. Also synchronizes the preview with viewport changes and refines mask expansion/contraction logic for improved accuracy and performance.
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.
Introduces a 'blendArea' property to layers and UI controls for adjusting it. Implements distance field mask generation in ImageAnalysis.ts and applies the mask during layer rendering for smooth edge blending. Refactors CanvasRenderer to delegate layer drawing to CanvasLayers for proper blend area support.
