• right means that the lines of label text are aligned to the right of the label bounds.
• center means that the center of the label text lines are aligned to the center of the label bounds.

Note that this value does not affect the positioning of the overall label bounds relative to the vertex. To move the label bounds horizontally, use labelPosition.

This defines if the direction style should be taken into account when computing the fixed point location for connected edges. See also direction.

Set this to false to ignore the direction style for fixed connection points.

For vertex, this defines the rounding factor for a rounded vertex in percent. The possible values are between 0 and 100. If this value is not specified, then constants.RECTANGLE_ROUNDING_FACTOR * 100 is used.

• Rhombus
• Swimlane
• Triangle

For edge, this defines the absolute size of the rounded corners in pixels. If this value is not specified, then LINE_ARCSIZE is used.

See also absoluteArcSize.

The possible values are empty or fixed. If fixed is used, the aspect ratio of the cell will be maintained when resizing.

This specifies if a cell should be resized automatically if its value changed. This is normally combined with resizable to disable manual resizing.

The type of this value is a space-separated list of numbers that specify a custom-defined dash pattern. Only relevant if dashed is true.

Dash styles are defined by the length of the dash (the drawn part of the stroke) and the length of the space between the dashes.

The lengths are relative to the line width: a length of 1 is equal to the line width.

See also dashed and fixDash.

This specifies if a cell can be deleted.

Generally, and by default in maxGraph, gradient painting is done from the value of fillColor to the value of gradientColor. If we take the example of 'north', this means that the fillColor color is at the bottom of paint pattern and the gradientColor color is at the top, with a gradient in-between.

This value only applies to vertices. If the shape is swimlane, a value of false indicates that the swimlane should be drawn vertically, true indicates that it should be drawn horizontally. If the shape style does not indicate that this vertex is a 'swimlane', this value only affects whether the label is drawn horizontally or vertically.

The possible values are any image URL.

This is the path to the image that is to be displayed within the label of a vertex. Data URLs should use the following format: data:image/png,xyz where xyz is the base64 encoded data (without the "base64"-prefix).

The label alignment defines the position of the label relative to the cell.

• left means that the entire label bounds is placed completely just to the left of the vertex.
• right means that the label bounds are adjusted to the right.
• center means that the label bounds are vertically aligned with the bounds of the vertex.
• ignore means that there is no alignment

The possible range is 0-100.

Defines if the connection points on either end of the edge should be computed so that the edge is vertical or horizontal if possible and if the point is not at a fixed location. The computation of the connection points involves the perimeter.

This is used in Graph.isOrthogonal, which is in charge of determining if the edge terminals should be orthogonal.

If the orthogonal property is not explicitly set but the edgeStyle belongs to one of the "orthogonal" EdgeStyle connectors, for example when using EdgeStyle.SegmentConnector or EdgeStyle.EntityRelation, the Graph.isOrthogonal method which also returns true.

Use this style to specify if loops should be routed using an orthogonal router. Currently, this uses EdgeStyle.OrthConnector but will be replaced with a dedicated orthogonal loop router in later releases.

This value specifies how overlapping vertex labels are handled.

• A value of 'visible' will show the complete label.
• A value of 'hidden' will clip the label so that it does not overlap the vertex bounds.
• A value of 'fill' will use the vertex bounds.
• A value of 'width' will use the vertex width for the label.

See Graph.isLabelClipped.

Note that the vertical alignment is ignored for overflow filling and for horizontal alignment.

This defines the perimeter around a particular shape.

For PerimeterFunction types, some possible values are the functions defined in Perimeter.

Alternatively, use a string or a value from PERIMETER to access perimeter styles registered in StyleRegistry. If GraphView.allowEval is set to true, you can pass the PerimeterFunction implementation directly as a string. Remember that enabling this switch carries a possible security risk

WARNING: explicitly set the value to null or undefined means to not use any perimeter. To use the perimeter defined in the default vertex, do not set this property.

This is the distance between the connection point and the perimeter in pixels.

• When used in a vertex style, this applies to all incoming edges to floating ports (edges that terminate on the perimeter of the vertex).
• When used in an edge style, this spacing applies to the source and target separately, if they terminate in floating ports (on the perimeter of the vertex).
