' This example demonstrates how to set a garbage matte mask for a 
' ColorCorrect operator in the FxTree, scale it, change the position
' of its center and then rotate it around the new center.
'
' 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," _

' 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
