Members

clickableboolean

It is clickable or not.

dataInfoObject

The additional data with shape.

heightnumber

The drawn height, the default it the image height.

highlightStyleObject

The highlight style object can be set with the same style properties as the style's set style properties.

hoverableboolean

It is hoverable or not.

imagestring Object

The address of the image.

isHoverByRefDataIDboolean

Whether to highlight in accordance with refDataID. It is used to highlight all geometries with the same refDataID.

refDataHoverGroupstring

The group name of highlight geometries. It is valid only when refDataID is valid and isHoverByRefDataID is true. Once the property is set and is valid, geometries associated with the same data and has the same property can be highlighted.

refDataIDstring

Data ID associated with shape.（<SuperMap.Feature.Vector> ID）。

refOriginalPositionArray

Shape's reference original position, shape's reference center position. refOriginalPosition is an array, the first element represents x coordinate, and the second element represents y coordinate.

refOriginalPosition represents shape's reference center. In general, the origin of canvas is the reference position. But you can change the reference position by refOriginalPosition. e.g. refOriginalPosition = [80, 80], circle style.x = 20, style.y = 20, so the real position of the circle in canvas is [100, 100].

All position properties of shape is based on the reference center of refOriginalPosition. In other words, the position of shape in canvas is relative position on the basis of refOriginalPosition. Only when refOriginalPosition is [0, 0], the shape position is the absolute position of canvas.

The information of shape position has：style.pointList，style.x，style.y。

refOriginalPosition. The default value is [0, 0].

Default Value:

[0,0]

Create a shape. The specific shape is determined by shapeParameters.

Name	Type	Description
shapeParameters	Object	Shape parameter object,<SuperMap.Feature.ShapeParameters> child class object. Optional. If using the parameter which isn't null, shapeParameters will be assigned to the parameter value, and then use shapeParameters to create a shape; If not using this parameter, the createShape method will directly use shapeParameter to create the shape.
