Class: QgsCurvedLineCallout¶

Draws curved lines as callouts.

Added in version 3.20.

Class Hierarchy¶

Base classes¶

`QgsSimpleLineCallout`	A simple direct line callout style.
`QgsCallout`	Abstract base class for callout renderers.

Methods

`curvature`	Returns the callout line's curvature.
`orientation`	Returns the callout line's curve orientation.
`setCurvature`	Sets the callout line's curvature.
`setOrientation`	Sets the callout line's curve orientation.

Static Methods

create

Creates a new QgsCurvedLineCallout, using the settings serialized in the properties map (corresponding to the output from QgsCurvedLineCallout.properties() ).

Attributes

`Automatic`
`Clockwise`
`CounterClockwise`

static create(properties: Dict[str, Any] = {}, context: QgsReadWriteContext = QgsReadWriteContext()) → QgsCallout | None[source]¶

Creates a new QgsCurvedLineCallout, using the settings serialized in the properties map (corresponding to the output from QgsCurvedLineCallout.properties() ).

Parameters:

properties (Dict[str, Any] = {})
context (QgsReadWriteContext = QgsReadWriteContext())

Return type:

Optional[QgsCallout]

curvature(self) → float[source]¶

Returns the callout line’s curvature.

The curvature is a percentage value (with typical ranges between 0.0 and 1.0), representing the overall curvature of the line.

setCurvature()

Return type:: float

orientation(self) → QgsCurvedLineCallout.Orientation[source]¶

Returns the callout line’s curve orientation.

See also

setOrientation()

Return type:: QgsCurvedLineCallout.Orientation

setCurvature(self, curvature: float)[source]¶

Sets the callout line’s curvature.

The curvature is a percentage value (with typical ranges between 0.0 and 1.0), representing the overall curvature of the line.

Parameters:: curvature (float)

setOrientation(self, orientation: QgsCurvedLineCallout.Orientation)[source]¶

Sets the callout line’s curve orientation.
