Move2DShapeLHandle

Introduced

v3.0

Description

Moves the left handle of a point on a Bezier 2D shape to adjust its shape. This is the scripting equivalent of clicking and dragging anywhere on the line between any two points on a Bezier shape to get the handles and then adjusting the left handle.

Note: You can also use the Move2DShapePoint command to move a point on the shape.

Scripting Syntax

Move2DShapeLHandle( [Shape], [index], [x], [y] );

Parameters

Parameter Type Description
Shape String Parameter path name for the shape whose handles you are moving.

Default Value: Current selection.

Note: If the current selection is not a valid shape, an error occurs.

index Long Specifies the index of the point to manipulate.

Default Value: If no value is specified for this argument, the left handle on the first point in the shape is moved.

x Double Specifies the new position in X for the handle.

Default Value: 0

y Double Specifies the new position in Y for the handle.

Default Value: 0

Examples

VBScript Example

'

' This example demonstrates how to set a garbage matte mask for a 

' ColorCorrect operator in the FxTree and then use the bezier handles

' to refine it.

'

' Create a new FxTree 

set oTree = CreateFxTree()

' Get the projects path for the current system

sPath = InstallationPath( siProjectPath )

set oClip = CreateImageClip( sPath & "\Pictures\noIcon.pic", "NewClip" )

' Use the clip to create a new image clip operator

set oOperator = AddImageClipFxOp( oTree, oClip )

' Add a Color Correct operator to the same tree

set oCCOp = AddFxOp( oTree, "Color Correct" )

' Connect the two operators

ConnectFxOp oOperator, oCCOp, "1" 

' Since the ConnectFxOp command does not return the new operator,

' you need to get it from the OperatorCollection on the FxTree object

for each oMember in oTree.FxOperators

	if oMember.Name = "ColorCorrect" then

		set oGBMatteOp = oMember

		exit for

	end if

next

' Adjust the HSV Offset and Gain levels so you can see the 

' results of the color correction

SetValue oGBMatteOp.FullName & ".MasterHueShift," _

		& oGBMatteOp.FullName & ".MasterOffset," _

		& oGBMatteOp.FullName & ".MasterGain", _

		Array(0, 0.820731514055631, 0.852844886888196)

' Add the 2D shape (mask shape) to the GarbageMatte and reshape it so you can see

' the shape when you open the Fx Viewer with the ColorCorrect operator selected

set oRotospline = Add2DShape( oGBMatteOp & ".GarbageShapes", "Bezier" )

Move2DShapePin oRotospline, 124.333333333333, 145.166666666667

aPointPositions = Array(56, 207, 196, 170, 179, 85, 132, 142, 108, 105, 75, 162)

Add2DShapePointArray oRotospline, aPointPositions

' Move the right handle of the first point and the left handle of the second

' point to create an arc on the top part of the shape

Move2DShapeRHandle oRotospline, , 15.0845123157596, 50.9829157526202

Move2DShapeLHandle oRotospline, 1, 15.0845123157597, 50.9829157526202
