Stroke (outline) dash array of the marker.

`Protected`_strokeWidth

_strokeWidth: number = 0

defaultSize

defaultSize: ISize = ...

The default marker size when the marker is created with a click (without dragging).

height

height: number = 0

Marker height.

left

left: number = 0

x coordinate of the top-left corner.

`Optional`notes

notes?: string

Additional information about the marker.

Generally, this isn't used for anything functional. However, in a derived type it could be used for storing arbitrary data with no need to create extra properties and state types.

`Optional`onSizeChanged

onSizeChanged?: (textMarker: TextMarker) => void

Callback to be called when the text size changes.

padding

padding: number = 2

Text padding from the bounding box.

rotationAngle

rotationAngle: number = 0

Marker's rotation angle.

stage

stage: MarkerStage = 'normal'

Most markers are created immediately after the user clicks on the canvas (normal). However, some markers are only finished creating after additional interactions (creating).

textBlock

textBlock: TextBlock = ...

Text block handling the text rendering.

textBoundingBox

textBoundingBox: DOMRect

Text's bounding box where text should fit and/or be anchored to.

`Static`title

title: string = 'Text marker'

Marker type title (display name) used for accessibility and other attributes.

top

top: number = 0

y coordinate of the top-left corner.

`Static`typeName

typeName: string = 'TextMarker'

It's important to set this in each derived class. This value is used to identify marker types when restoring marker state and other scenarios.

width

width: number = 0

Marker width.
