Properties

antiAlias

antiAlias: boolean = true

Rendering hint for configuring the canvas.

boundingBox

boundingBox: null | Rectangle = null

Contains the bounding box of the shape, that is, the smallest rectangle that includes all pixels of the shape.

bounds

bounds: null | Rectangle = null

Holds the Rectangle that specifies the bounds of this shape.

cursor

cursor: string = ''

dialect

dialect: null | string = null

Holds the dialect in which the shape is to be painted. This can be one of the DIALECT constants in Constants.

direction

direction: DirectionValue = DIRECTION.EAST

endArrow

endArrow: string = NONE

endSize

endSize: number = 1

fill

fill: string = NONE

fillOpacity

fillOpacity: number = 100

flipH

flipH: boolean = false

flipV

flipV: boolean = false

glass

glass: boolean = false

gradient

gradient: string = NONE

gradientDirection

gradientDirection: DirectionValue = DIRECTION.EAST

image

image: null | ImageBox = null

imageSrc

imageSrc: null | string = null

indicator

indicator: null | Shape = null

indicatorColor

indicatorColor: string = NONE

indicatorDirection

indicatorDirection: DirectionValue = DIRECTION.EAST

indicatorGradientColor

indicatorGradientColor: string = NONE

indicatorImageSrc

indicatorImageSrc: null | string = null

indicatorShape

indicatorShape: null | typeof Shape = null

indicatorStrokeColor

indicatorStrokeColor: string = NONE

isDashed

isDashed: boolean = false

isRounded

isRounded: boolean = false

isShadow

isShadow: boolean = false

minSvgStrokeWidth

minSvgStrokeWidth: number = 1

Minimum stroke width for SVG output.

node

node: SVGGElement

Holds the outermost DOM node that represents this shape.

oldGradients

oldGradients: GradientMap = {}

opacity

opacity: number = 100

originalPointerEvents

originalPointerEvents: null | boolean = null

outline

outline: boolean = false

Specifies if the shape should be drawn as an outline. This disables all fill colors and can be used to disable other drawing states that should not be painted for outlines. Default is false. This should be set before calling .

overlay

overlay: null | CellOverlay = null

pointerEvents

pointerEvents: boolean = true

Specifies if pointer events should be handled. Default is true.

points

points: (null | Point)[] = []

Holds the array of that specify the points of this shape.

preserveImageAspect

preserveImageAspect: boolean = false

rotation

rotation: number = 0

scale

scale: number = 1

Holds the scale in which the shape is being painted.

shapePointerEvents

shapePointerEvents: boolean = false

Specifies if pointer events outside of shape should be handled. Default is false.

spacing

spacing: number = 0

startArrow

startArrow: string = NONE

startSize

startSize: number = 1

state

state: null | CellState = null

Optional reference to the corresponding .

stencil

stencil: null | StencilShape = null

Holds the StencilShape that defines the shape.

stencilPointerEvents

stencilPointerEvents: boolean = false

Specifies if pointer events outside of stencils should be handled. Default is false. Set this to true for backwards compatibility with the 1.x branch.

stroke

stroke: string = NONE

strokeOpacity

strokeOpacity: number = 100

strokeWidth

strokeWidth: number = 1

style

style: null | CellStateStyle = null

Optional reference to the style of the corresponding .

svgPointerEvents

svgPointerEvents: string = 'all'

Specifies if pointer events should be handled. Default is true.

svgStrokeTolerance

svgStrokeTolerance: number = 8

Event-tolerance for SVG strokes (in px). This is only passed to the canvas in createSvgCanvas if pointerEvents is true.

Default

8

useSvgBoundingBox

useSvgBoundingBox: boolean = true

Allows to use the SVG bounding box in SVG. Default is false for performance reasons.

verticalTextRotation

verticalTextRotation: number = 0

visible

visible: boolean = true

Specifies if the shape is visible. Default is true.

Methods

addPoints

  • addPoints(c, pts, rounded?, arcSize, close?, exclude?, initialMove?): void

  • Paints the given points with rounded corners.

    Parameters

    • c: AbstractCanvas2D
    • pts: Point[]
    • rounded: boolean = false
    • arcSize: number
    • close: boolean = false
    • exclude: number[] = []
    • initialMove: boolean = true

    Returns void

afterPaint

apply

  • apply(state): void

  • Applies the style of the given to the shape. This implementation assigns the following styles to local fields:

    • <'fillColor'> => fill
    • <'gradientColor'> => gradient
    • <'gradientDirection'> => gradientDirection
    • <'opacity'> => opacity
    • Constants#STYLE_FILL_OPACITY => fillOpacity
    • Constants#STYLE_STROKE_OPACITY => strokeOpacity
    • <'strokeColor'> => stroke
    • <'strokeWidth'> => strokewidth
    • <'shadow'> => isShadow
    • <'dashed'> => isDashed
    • <'spacing'> => spacing
    • <'startSize'> => startSize
    • <'endSize'> => endSize
    • <'rounded'> => isRounded
    • <'startArrow'> => startArrow
    • <'endArrow'> => endArrow
    • <'rotation'> => rotation
    • <'direction'> => direction
    • <'glass'> => glass

    This keeps a reference to the
