The SetNodes2 method sets the node positions and colors for a color spectrum file. This method is the same as the SetNodes method, except it takes the pointer to the array. VB users may want to call this method instead of SetNodes. Note: Golden Software does not officially support VB.
Syntax
object.SetNodes2( Positions, Colors )
|
Parameter |
Type |
Description |
|
Positions |
Array of Doubles |
required; node positions from 0.0 to 1.0 |
|
Colors |
Array of Longs |
required; node colors |
Remarks
The first element in the Positions array must equal zero, and the last element must equal 1.0. Positions and Colors must have the same number of elements (at least two). VB users can use ReDim to set the array size to the used size if necessary.
Example
This example demonstrates how to create a custom color spectrum file.
Dim Positions(6) As Double
Positions(0)=0.0
Positions(1)=0.1
Positions(2)=0.25
Positions(3)=0.5
Positions(4)=0.75
Positions(5)=0.9
Positions(6)=1.0
Dim Colors(6) As Long
Colors(0)= mvColorBlack
Colors(1)=mvColorBlue
Colors(2)=mvColorGreen
Colors(3)= mvColorYellow
Colors(4)= mvColorOrange
Colors(5)=mvColorRed
Colors(6)= mvColorWhite
ColorSpectrum.SetNodes2(Positions:=Positions, Colors:=Colors)
