Scripting: Move2DShapeLHandle

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" )

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
