Add2DShapePointArray

Introduced

v3.0

Description

Adds an array of points to a 2D shape (mask shape).

The difference between this command and the Insert2DShapePoint command is that you use Add2DShapePointArray to define the original set of points while creating the shape, but Insert2DShapePoint adds points to an existing shape after it has been created.

Note: You can add points using either the Add2DShapePoint or Add2DShapePointArray commands.

Scripting Syntax

Add2DShapePointArray( [Shape], points );

Parameters

Parameter Type Description
Shape String Parameter path name for the shape where you are defining the point(s).

Default Value: Current selection.

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

points Array of Doubles Specifies the position of the new point as a 1-dimensional array of x,y values.

Examples

VBScript Example

'

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

' ColorCorrect operator in the FxTree.

'

' 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

' Print out the RGB values

getRGBValues oRotospline

' Set new values and print out the new results

setRGBValues oRotospline, 2, 3, 5

getRGBValues oRotospline

' ---------------------- FUNCTIONS ----------------------------------

function getRGBValues( in_roto_name )

	' Get the RGB Values from the rotospline shape

	vRed = GetValue( oRotospline & ".Red", 1 )

	vGreen = GetValue( oRotospline & ".Green", 1 )

	vBlue = GetValue( oRotospline & ".Blue", 1 )

	Application.LogMessage "The RGB values for the " & oRotospline _

			& " are: " & vRed & ", " & vGreen & ", " & vBlue

end function

function setRGBValues( in_roto_name, in_R, in_G, in_B )

	SetValue oRotospline & ".Red", in_R

	SetValue oRotospline & ".Green", in_G

	SetValue oRotospline & ".Blue", in_B

end function



' ------------------------ OUTPUT -----------------------------------

' Output of above script:

'INFO : "The RGB values for the FxTree.ColorCorrect_Image.ColorCorrect.GarbageShapes.Bezier are: 1, 1, 1"

'INFO : "The RGB values for the FxTree.ColorCorrect_Image.ColorCorrect.GarbageShapes.Bezier are: 2, 3, 5"
