Scripting: Delete2DShapePoint

Delete2DShapePoint

Introduced

v3.0

Description

Deletes a single point from a 2D shape (mask shape). This is the scripting equivalent of selecting a point on the shape in the Fx Viewer and then clicking the Delete button in the ColorCorrect property page.

Scripting Syntax

Delete2DShapePoint( [Shape], [index] );

Parameters

Parameter	Type	Description
Shape	String	Parameter path name for the shape where you are deleting the point. 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 delete. Default Value: If no value is specified for this argument, the first point in the shape is deleted.

Examples

VBScript Example

'
' This example demonstrates how to set a garbage matte mask for a 
' ColorCorrect operator in the FxTree, and then add, move, delete, 
' and key points on the existing shape.
'
' 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", _
