Detailed Description

Represents the orientation of a marker.

Member Enumeration Documentation

MarkerType

enum class donner::svg::MarkerOrient::MarkerType : uint8_t

strong

For computeAngleRadians, to specify if this is the marker-start orientation.

Enumerator
Default	The default orientation.
Start	The marker-start orientation.

Type

enum class donner::svg::MarkerOrient::Type : uint8_t

strong

The type of the orientation.

Enumerator
Angle	Contains a user-provided angle.
Auto	The angle is computed from the direction vector.
AutoStartReverse	Like Auto, but for marker-start the direction is reversed.

Member Function Documentation

AngleDegrees()

MarkerOrient donner::svg::MarkerOrient::AngleDegrees ( double angleDegrees )

inlinestatic

Creates a new orientation with a user-provided angle in radians.

Parameters

angleDegrees

The angle in Degrees.

Returns

The new orientation.

AngleRadians()

MarkerOrient donner::svg::MarkerOrient::AngleRadians ( double angleRadians )

inlinestatic

Creates a new orientation with a user-provided angle in radians.

Parameters

angleRadians

The angle in radians.

Returns

The new orientation.

Auto()

MarkerOrient donner::svg::MarkerOrient::Auto ( )

inlinestatic

Creates a new orientation that computes the angle from the direction vector.

Returns

The new orientation.

AutoStartReverse()

MarkerOrient donner::svg::MarkerOrient::AutoStartReverse ( )

inlinestatic

Creates a new orientation that computes the angle from the direction vector, but reverses the direction for marker-start.

Returns

The new orientation.

computeAngleRadians()

double donner::svg::MarkerOrient::computeAngleRadians ( const Vector2d & direction, MarkerType markerType = MarkerType::Default ) const

inline

Computes the angle in radians based on the direction vector and the type of orientation.

Parameters

direction	The direction vector.
markerType	Set to MarkerType::Start if this is the marker-start orientation.

Returns

The angle in radians.
