## 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
