The canvas was getting corrupted to a small strip because of confusion
between two different dimension types:
- Output area dimensions (logical working area, e.g. 512x512)
- Display canvas dimensions (actual pixels shown on screen)
Root cause: Setting canvas.width/height attributes to match output area
while also using CSS width:100%/height:100% created conflicts. When
zooming or reloading, wrong dimensions would be read and saved.
Fix: Remove canvas element width/height attribute assignments. Let the
render loop control display size based on clientWidth/clientHeight.
Keep output area dimensions separate.
This prevents the canvas from being saved with corrupted tiny dimensions
and fixes the issue where canvas would only show in a small strip after
zooming or reloading workflows.
Enhanced LayerForge input handling to strictly separate image and mask loading based on connection type. Images now only load when allowImage=true and masks only when allowMask=true, preventing unintended cross-loading between input types.
Implemented dynamic brush cursor with visual feedback for size (circle radius), strength (opacity), and hardness (solid/dashed border with gradient). Added overlay canvas system for smooth cursor updates without affecting main rendering performance.
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.
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.
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.
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.
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.
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.
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 'visible' property to layers and updates all relevant logic to support toggling layer visibility. Adds visibility toggle icons to the layers panel using a new IconLoader utility, with SVG and fallback canvas icons. Updates rendering, selection, and batch preview logic to respect layer visibility. Also improves blend mode menu UI and ensures new/pasted layers are always added on top with correct z-index.
Introduces ShapeTool to allow users to define custom polygonal output areas by holding Shift+S and clicking to add points. The selected shape is used to crop and mask images and layers, and is visualized on the canvas. Updates Canvas, CanvasIO, CanvasInteractions, CanvasLayers, CanvasRenderer, and types to support shape-based output areas, including shape-aware import, export, and rendering logic.
Adds the willReadFrequently: true option to all getContext('2d') calls on temporary canvases in Canvas, CanvasLayers, and SAMDetectorIntegration modules. This improves performance for frequent pixel data reads, addressing potential browser optimization issues.
Replaces setPreviewVisibility(false) with direct assignment to previewVisible in Canvas and Canvas.ts. Adds initialization of preview state based on widget value in CanvasView and CanvasView.ts to ensure correct preview visibility on widget creation.
Replaces the local auto-refresh toggle with a node widget property 'auto_refresh_after_generation' in both JS and TS Canvas classes. Updates Python CanvasNode to include this property in the required config and removes 'hidden' from 'trigger' and 'node_id'. This change centralizes auto-refresh state in the node widget for better consistency and UI integration.
