    • getAdjustedBottomLeftModelCoordinates

      public javafx.geometry.Point2D getAdjustedBottomLeftModelCoordinates()
      Returns the bottom-left corner coordinates of the visible area in model space, adjusted for both the palette offset and ruler dimensions. This method:
      • Accounts for the horizontal palette offset (right side of palette)
      • Maintains original vertical position (no vertical offset)
      • Reflects current zoom level for accurate coordinate calculation
      The adjusted coordinates represent the starting point (minimum X and Y values) of the visible content area after excluding:
      • The palette width on the left side
      • The horizontal ruler height at the top
      Returns:
      Point2D representing adjusted bottom-left coordinates in model space, where:
      • X: Original X + (palette width / current zoom)
      • Y: Original Y coordinate (unmodified)

    • getAdjustedVisibleAreaModelSize

      public javafx.geometry.Point2D getAdjustedVisibleAreaModelSize()
      Returns the visible area dimensions in model space, adjusted for both the palette offset and ruler dimensions. This method:
      • Subtracts the palette width from horizontal visibility
      • Maintains full vertical visibility height
      • Accounts for current zoom level for accurate dimension calculation
      The returned dimensions represent the visible content area after excluding:
      • The palette width on the left side
      • The horizontal ruler height at the top
      Returns:
      Point2D representing adjusted visible area dimensions in model space, where:
      • X: Visible width - (palette width / current zoom)
      • Y: Full visible height (unmodified)

      public void resize(double width, double height)
      Overrides:
      resize in class javafx.scene.layout.Region

    • setRulersVisible

      public void setRulersVisible(boolean visible)
      Sets the visibility state of both rulers (horizontal and vertical) and the associated grid. When set to true:
      • Horizontal ruler becomes visible at the top of the content area
      • Vertical ruler becomes visible on the left side of the content area
      • Grid lines aligned with ruler ticks become visible
      • Ruler positions are recalculated to account for current palette width
      When set to false:
      • All ruler components are hidden
      • Grid lines are immediately removed
      Parameters:
      visible - true to show rulers and grid, false to hide them

    • isRulersVisible

      public boolean isRulersVisible()
      Returns the current visibility state of the rulers and grid.
      Returns:
      true if rulers and grid are currently visible, false if hidden

    • setRulerOffset

      public void setRulerOffset(double offset)
      Sets the horizontal offset for rulers to accommodate external components (typically a palette). This method:
      • Adjusts both horizontal and vertical ruler positions
      • Triggers immediate ruler repositioning and redraw
      • Updates grid calculations to match new layout
      • Maintains ruler/grid alignment with content area
      The offset represents the horizontal space (in pixels) that should be reserved on the left side of the canvas before the content area starts.
      Parameters:
      offset - Horizontal space in pixels to offset rulers from left edge. Must be ≥ 0. Typical value equals palette width.

    • setTileLayerShape

      public void setTileLayerShape(com.amalgamasimulation.animation.shapes.shapes2d.GroupShape groupShape)
      Sets the tile layer content from a GroupShape
      Parameters:
      groupShape - the shape container to render as the tile layer

    • setTileLayerVisible

      public void setTileLayerVisible(boolean visible)
      Controls the visibility of the tile layer
      Parameters:
      visible - true to show the tile layer, false to hide

    • getTileLayerSiblingsPoints

      public Set<Point> getTileLayerSiblingsPoints(double x, double y)
      Retrieves all distinct endpoints of line segments located in the tile containing the specified point and its eight neighboring tiles.

    • isTileLayerVisible

      public boolean isTileLayerVisible()
      Gets the current visibility state of the tile layer
      Returns:
      true if the tile layer is visible, false if hidden

    • getTileLayerModelBounds

      public double[] getTileLayerModelBounds()
      Union of visible surface raster tile bounds in model space ([minX, minY, maxX, maxY]), or null when the tile layer is hidden or has no loaded tiles.
