Visible Fields

Use End Settings For Start Arrow Head

name: useEndSettingsForStartArrowHead, type: Bool, default: TRUE

If checked, the settings for the end arrow head are used for the start arrow head.

End Size

name: endSize, type: Float, default: 10, minimum: 0

Sets the size of the end arrow head.

End Angle Factor

name: endAngleFactor, type: Float, default: 1

Sets an angle factor for the end arrow head.

End Rendering Style

name: endRenderingStyle, type: Enum, default: RENDERING_STYLE_LINES

Defines the rendering style for the end arrow head.

Values:

Title	Name	Description
Lines	RENDERING_STYLE_LINES	The arrow head is rendered as simple lines (open triangle).
Triangle	RENDERING_STYLE_TRIANGLE	The arrow head is rendered as a closed triangle.
Filled Triangle	RENDERING_STYLE_FILLED_TRIANGLE	The arrow head is rendered as a closed and filled triangle.
None	RENDERING_STYLE_NONE	No arrow head is rendered.

End Direction

name: endDirection, type: Enum, default: DIRECTION_MODE_STANDARD

Defines the direction mode of the end arrow head.

Note that the sign of the End Angle Factor can also be used to flip the direction of the arrow head.

Values:

Title	Name	Description
Standard	DIRECTION_MODE_STANDARD	Standard rendering.
Reverse	DIRECTION_MODE_REVERSE	The direction is reversed.
Automatic	DIRECTION_MODE_AUTOMATIC	The direction depends on the length of the vector.

Length Threshold (pixel) (endDirectionAutomaticLengthThreshold)

name: endDirectionAutomaticLengthThreshold, type: Float, default: 10

Sets a vector length threshold in pixel. If length of the vector is shorter than this threshold, the end arrow direction is reversed.

Start Size

name: startSize, type: Float, default: 10, minimum: 0

Sets the size of the start arrow head.

Start Angle Factor

name: startAngleFactor, type: Float, default: 1

Sets an angle factor for the start arrow head.

Start Rendering Style

name: startRenderingStyle, type: Enum, default: RENDERING_STYLE_LINES

Defines the rendering style for the start arrow head.

Values:

Title	Name	Description
Lines	RENDERING_STYLE_LINES	The arrow head is rendered as simple lines (open triangle).
Triangle	RENDERING_STYLE_TRIANGLE	The arrow head is rendered as a closed triangle.
Filled Triangle	RENDERING_STYLE_FILLED_TRIANGLE	The arrow head is rendered as a closed and filled triangle.
None	RENDERING_STYLE_NONE	No arrow head is rendered.

Start Direction

name: startDirection, type: Enum, default: DIRECTION_MODE_STANDARD

Defines the direction mode of the start arrow head.

Note that the sign of the Start Angle Factor can also be used to flip the direction of the arrow head.

Values:

Title	Name	Description
Standard	DIRECTION_MODE_STANDARD	Standard rendering.
Reverse	DIRECTION_MODE_REVERSE	The direction is reversed.
Automatic	DIRECTION_MODE_AUTOMATIC	The direction depends on the length of the vector.

Length Threshold (pixel) (startDirectionAutomaticLengthThreshold)

name: startDirectionAutomaticLengthThreshold, type: Float, default: 10

Sets a vector length threshold in pixel. If length of the vector is shorter than this threshold, the start arrow direction is reversed.
