Initializes a new
GrayScaleToDuotoneCommand class object with explicit parameters.
Syntax
Parameters
- newColor
- Array of RasterColor structures that specifies colors that will be mixed with the original gray values. If this parameter is set to null, the Color property must contain a valid color. Pass null when you want the command to create the array of colors, two colors when replacing both colors in a binary image, or 256 colors when using a custom array of colors.
- color
- Used to create an array of colors internally. This parameter is used when the NewColor structure is set to null. This parameter is ignored if the NewColor value is something other than null.
- type
- Enumeration that indicates whether colors will be mixed or replaced.

Public Sub GrayScaleToDuetoneConstructorExample()
RasterCodecs.Startup()
Dim codecs As New RasterCodecs()

Dim leadImage As RasterImage = codecs.Load("C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Master.jpg")
Dim array() As RasterColor
Dim i As Integer
ReDim array(255)
For i = 0 To 255
array(i) = New RasterColor(255, CType(i \ 4, Byte), CType(i, Byte))
Next
Dim command As GrayScaleToDuotoneCommand = New GrayScaleToDuotoneCommand(array, Nothing, GrayScaleToDuotoneCommandMixingType.ReplaceOldWithNew)
command.Run(leadImage)
codecs.Save(leadImage, "C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\Result.jpg", RasterImageFormat.Jpeg, 24)
RasterCodecs.Shutdown()
